High Dynamic Range Photography

Camera sensor technology has come a long way in recent years but the one thing a camera can't do is to record what the human eye sees. In terms of light's dynamic range, sensors fall short in their ability to record detail in both the whites and blacks of an image at the same time unlike the human eye. Estimates suggest that the human eye can see anywhere between 10-14 f-stops of dynamic range whereas a camera sensor is about 8-11 f-stops. Each yearly improvement in sensor technology brings the camera's dynamic range closer to human sight albeit very slowly.

It's for this reason that in high contrasting landscape shots depending on which exposure mode the camera is set to and where in the image you have the horizon, the result will be either a blown out white sky with no detail and a well exposed foreground or visa versa.

Exposed for the foreground - blown out sky

Exposed for the sky - under exposed foreground

Always shooting in RAW for the best image quality, once the highlights in a sky have been blown out there's no chance of recovering any detail but there is the possibility of recovering detail from the foreground of an under exposed RAW image to create an acceptable single shot image. The solution that I prefer while the camera is already on a sturdy tripod is to simply take an extra shot and create a three shot HDR (high dynamic range) photograph. 

The first two photographs above are unprocessed RAW images out of camera while the finished photograph of Llyn Dinas in Snowdonia (below) is a three shot HDR with the exposure "averaged" out in HDR software. The result is dramatic with detail in both the sky and the shadows. The photograph has punch. 

Three shot HDR of Llyn Dinas in Snowdonia

The other way of overcoming these restrictions in dynamic range is by using a graduated neutral density filter on a filter holder screwed onto your lens. The "Grad ND" is darker on the top half of the glass filter with the lower half clear and it's designed to balance out the exposure in landscape photography but there is a drawback. They're fine for straight horizons but what about when you're photographing a horizon which are undulating such as mountains, trees or a cityscape full of buildings?

I gave up on "Grad ND" filters many years ago for landscape photography because they're expensive, cumbersome and slow to use and I find the technique of taking multiple exposures and blending them together to be more convenient when shooting and flexible when post processing. If I take five or seven bracketed shots of a scene with the cameras multi metering set to 0 in the viewfinder I can choose in post processing to use a single image to process or any number of them together as a HDR photograph. Shooting a series in burst mode takes a split second and card storage is cheap. Any unwanted shots can be deleted when on the computer.

The biggest drawback to capturing multiple exposures for creating HDR images is movement within the image. Modern HDR software is very adept at correcting "ghosting" in post processing. Often a five shot series of bracketed images in burst mode will be over in a split second and the software can handle minor movement well.

Pseudo HDR - Below Aber Falls

Sometimes the movement between shots will be too much for software to handle. In that case a method that I sometimes use to overcome movement is to create a "pseudo" HDR from a single image.

Shooting in RAW, take a shot with a well balanced exposure. You can adjust the exposure slider in your RAW converter to overexpose the shot by 2 stops and save, underexpose by 2 stops and save, then blend the three images together as a pseudo HDR. This technique was used on Below Aber Falls (above) one of my first HDR photos and it's brought out detail in both the moving water and the rocks many of which were in shadow. 

The modern technique is tone mapping a single image in HDR software. Tone mapping is a technique used to map one set of colours to another to approximate the appearance of HDR images.

Three shot HDR - Tower of London

Creating a HDR image is an ideal way of dealing with difficult lighting in any setting. The photograph of London Tower (above) was taken in a very dark room lit only by the window. It was impossible to capture detail in the shadows of the furniture and the sun filled window in a single shot. This was achieved with a three shot burst bracketed at +-2EV either side of 0EV and processed in Photomatix Pro HDR software. The camera was hand held and braced against a wall for stability.

Three shot HDR - Dunham Massey

The same technique and settings were used to capture this photograph of Dunham Massey (above) with light streaming through a window. In fact I've used HDR photography to capture more interior scenes than landscapes due to them only being lit by natural light with a flashgun being barred from use or the building being too vast for flashgun light.

Three shot HDR - Lady Lever Art Gallery

Three shot HDR - Lady Chapel, Anglican Cathedral Liverpool

When you have the ability to use a tripod as in the shots of Lady Lever Art Gallery, Wirral and the Anglican Cathedral, Liverpool then shooting in HDR is the way to go but how many bracketed shots do you need to produce a good HDR image?

I've read articles claiming that three shots bracketed at +-2EV is sufficient and this is the method that I've mostly used and that I'm satisfied with. I've also read articles that claim that the more bracketed shots you take the greater the detail in the finished photograph and I've shot HDR images using five, seven and nine bracketed images on occasion. 

Five shot HDR - One Careful Owner

The photograph of One Careful Owner (above) taken on the Dee Estuary at Lower Heswall is a five shot HDR bracketed at +-1EV. Is there any more detail compared to a three shot image producing the same dynamic range? It's very hard to tell.

So what software do I use to produce HDR photographs. In my early days I used Photomatix Pro which is available to try and purchase. My software of choice for several years has been Aurora HDR by Luminar. It's very powerful with a huge range of sliders to produce the HDR look that you prefer. 

Photographs produced as HDR's have a certain "look" which doesn't appeal to everyone. At worst they can look grungy, but at their best they will have punch and a wow factor but care is needed in toning down a processed image to make it look more natural as the colours can often be overpowering. Every camera has the settings to produce HDR photos. Some even have the ability to do it "in camera" All you need is a tripod or steady hand and the software. Have fun.

Picfair Prints and Digital Downloads

Covid-19 has hit the local Wirral art scene extremely hard. Naturally under these difficult circumstances, art fairs, art events, shops and museums have either cancelled their planned events for 2020 or sadly closed down permanently and it's uncertain when things will get back to normal.

For me, one of the joys of taking photographs has always been watching them sell as prints and gift cards at local fairs or showing them in exhibitions. Talking to members of the public about my photography across an art fair stall was a lot of fun. Having them stored on a hard drive and not viewed at all is an incredibly sad prospect.

To compensate for Covid-19 restrictions and to get my work out there and seen, this blog is a big help, but I've also enlisted the help of Picfair. Picfair is a stock photography website that also provides a print on demand service. As well as being able to sell licenced images, Picfair offers a small range of Giclee prints, framed prints and canvass wrap options to a potential buyer. 

For a small £50 per year membership fee I've been able to build my own website hosted by Picfair to showcase my best photography under the name of George Evans Photography


Selling photography online is extremely difficult and I'm not expecting to make a fortune. In fact I'd be amazed if I'm able to get the £50 membership fee back in sales but linked to this blog it's a small price to pay to get an unlimited number of my wider images seen by the public. The blog can only do so much.

To date there are over 130 of my best photographs hosted on my new Picfair website with more being added weekly. Images can be viewed in albums from the drop down menu in the top left corner of the homepage. Of course there is no compulsion to buy or licence an image if you do visit but if you do then I hope that you find the pricing reasonable and comparable to my art fair prices. 

The reason for this new venture is to provide an opportunity to those who normally enjoy my photography but due to Covid-19 are now are unable to purchase locally, an outlet to owning a print. If you're not in the need for wall art then I sincerely hope that you get enjoyment out of simply visiting George Evans Photography and viewing the images. It won't cost you a penny. Thank you for your support.

Brimham Rocks

I've been photographing in infrared for 15 years starting off with the Sony F717 bridge camera with an R72 filter attached and experience has taught me that the best infrared photographs are a combination of foliage and hard landscaping in the form of water, rocks, buildings, fences etc. to prevent the problem of wall to wall whiteness where there's no contrast and no focal point for the eye to rest on. Hard landscaping as a stage set to show off the white foliage of infrared is in my opinion the best look for landscapes.

With that philosophy in mind I enjoyed an afternoon at the National Trusts Brimham Rocks in October 2018. Brimham Rocks, is a 184 hectare biological site of Special Scientific Interest on Brimham Moor in the Nidderdale Area of Outstanding Natural Beauty, 8 mls north west of Harrogate, North Yorkshire. 

Lone Tree at Brimham Rocks - 720nm channel swapped

Brimham Rocks have been sculptured by the ice, wind and rain of nature for thousands of years but many of the formations could easily be mistaken for Henry Moore art work occasionally peppered with lone trees rooted in shallow crags. This makes them a wonderful subject for photography whether it's infrared or traditional colour photography. 

720nm infrared - channel swapped

720nm infrared - channel swapped

During this visit all of my shooting was done with a Sony A6000 which has been permanently converted to the 720nm standard wavelength of infrared. The 720nm wavelength produces weak colour in the red and blue channels only. With the correct white balance set to green grass, the colours straight out of camera have a brown sky. Some of these images have been channel swapped to produce a blue sky as above, one has been processed with the colours straight out of camera with a brown sky and many were processed as traditional monochrome images. My go to lens for these infrared photographs was the excellent Zeiss 12mm f2.8 Touit which captures very sharp images without any hotspots.

720nm infrared - out of camera colour

Traditional "fine art" infrared photography has always been in monochrome. Producing infrared images has alway been a creative post processing exercise and there are 101 ways to process any Raw image but I've been slowly moving away from false colour towards the more traditional monochrome since this visit to Brimham Rocks. Does monochrome work better? That's subjective and a matter for your personal taste.

The weak Autumn light wasn't perfect for infrared and I've had to do some dodging of the highlights as a result to brighten and enhance the white foliage but the bonus was there were very few visitors to the site on the day which gave me free reign to shoot without being disturbed. I'd love to return during the Summer months when I expect the results and the atmosphere captured in the images will be very different.

Threlkeld Quarry and Mining Museum, Cumbria

The Lake District National Park in Cumbria is well known for its beautiful landscapes, picturesque lakes and green mountains. It's a year round draw for photographers from across the UK. In fact there seems to be more photographers in the National Park during the Winter months attempting to capture moody landscapes than during any other season but there's more to photography in the Lake District than landscapes.

In May 2017 I visited the Lake District with thirteen other members of Hoylake Photographic Society for a long weekend staying at the Field Study Center at Blencathra outside Keswick. On our first day at Blencathra the weather was grey with no interest at all in the sky making it unsuitable for good landscape photography. The best advice I've received from top landscape photographers over the years is, "If the sky isn't adding anything to the image then leave it out and shoot detail instead" and that's what I did.

Our group had made a list of interesting places to visit during our long weekend as each had their own photographic interests and on the list was the Threlkeld Quarry and Mining Museum which was only a few miles from our base just off the main A66 road into Keswick so a group of us decided to spend a few hours there before moving on and it proved to be a good decision. 

Opened in the 1870's to provide ballast to the railway industry the Threlkeld Quarry was closed in 1992 and it's become a museum largely run by volunteers. The extensive grounds are a home to vintage mining machinery, there's a narrow gauge steam railway, tours underground and a small museum. 

If there's one thing photographers love it's rot and decay whether it's in buildings, boats or vehicles and Threlkeld had plenty of detail to capture on a grey sky day. 



It was a good test of your photographers "eye" wandering around the derelict cranes and trucks picking out good compositions of flaking paint, cogs and rust. Two hours went by in a flash. When you're on a trip with a group who are car sharing there's always a compromise to be made and you have to move on to another location agreed by the group so time was limited. Another disadvantage of travelling as a group from the same photo society is that you're all taking the same photographs unless like me you're the only infrared photographer.

                   "Why capture what everyone else is shooting when you can shoot in infrared"

Having spent two hours photographing in colour I was told that the group were leaving in 15 minutes. I always take two cameras on a trip and I was using a Sony A6300 mirrorless and a Sony A6000 infrared converted camera. The A6000 had been permanently converted to the 590nm "Super Colour" wavelength of infrared and these shots taken at Threlkeld were captured with a B+W 0.93 infrared filter on the lens converting it to 830nm pure monochrome only infrared.



On the day the light was bright but with an overcast sky giving soft even light with no harsh shadows which was ideal for these infrared photographs. There are times when you want to highlight the strong colours in an image and there are times when the simplicity of monochrome infrared is best. Nature reclaiming these derelict machines would have been lost in a colour photograph.




When people think of infrared they envisage rolling landscapes with fluffy clouds and white foliage on trees but infrared is best when there's hard landscaping, bodies of water or inanimate objects to give contrast to the white otherwise the image can be a total white out with no focal point. Threlkeld was the perfect subject for infrared.

 


Shooting infrared in 830nm wavelength of light results in slow shutter speeds and a tripod is recommended but I didn't have much time so these were all taken hand held. Neither the A6000 or the lens had stabilisation and luckily there was no wind at all so a steady hand and controlled breathing helped to get theses sharp images. As I'd already been around the site shooting in colour I already knew the shots to get in infrared and I was able to achieve what I wanted in the 15 minutes before we moved on. It was a good start to an enjoyable weekend.

RSPB Burton Mere Wetlands

A month ago I bought myself a long lens (the Sigma 150-600mm Contemporary) with the intention of broadening my photography in to wildlife and sports. I'm lucky in that the Wirral Peninsula with a coastline on three sides is a haven for wildlife and there are some important protected habitats around the coast for anyone interested in bird photography. One such habitat is the RSPB Burton Mere Wetlands at Burton in South Wirral.

The wetlands are about four miles from my home and it has been a favourite location for my infrared landscape photography in the past but I've never had a lens long enough to capture the wildlife there until now so today I took the Sigma 150-600mm lens out for the day to put it through its paces. During the visit to the wetlands I also took the opportunity to sign up as a member of the RSPB.

I was warned before joining that it was the quietest time of the year for the wetlands as most of the feathered visitors arrived during the Winter months and they were true to their word. There were wild flowers, butterflies and dragonflies galore but I had the wrong lens with me for those subjects and the few ducks and geese on the water were too far away for even a 600mm lens. With the hides and some paths closed due to Covid-19 restrictions there were no real opportunities to get up close enough for photography. I met a group of twitchers who were watching a Peregrine Falcon circling around a group of geese on water in the distance but they were too small to photograph.

That's wildlife photography in a nutshell. Wildlife rarely comes out and poses for you. You have to research its behavior, be patient and have a little luck but I'm not deterred. My next visit as a new RSPB member will be with an infrared camera to capture the beauty of this site as I wait for opportunities to shoot with the long lens.

As I've no wildlife to show you from today's visit, I'll leave you with some infrared photographs that I've taken at Burton Mere Wetlands over the years. I'm lucky to have two reasons to visit in the future.

Going Long Again

I've been an amateur photographer for 17 years starting off with a Sony F717 bridge camera before buying my first DSLR, the Minolta5D with in body stabilisation. When I upgraded to my first Sony DSLR (Sony A700) I purchased a Sigma 170-500 f5-6.3 super zoom lens. It had no stabilisation which wasn't a problem as the A700 was stabilised and the performance was average but I wasn't a competitive club photographer in those days and used it to capture air shows and some wildlife simply for my own pleasure. 

The big drawback was the size and weight of the lens as it wouldn't fit in my camera bag so after a year I sold it and bought the more practical Sony 70-300 f4.5-5.6 SSM. I was heavily into macro flower photography at that time and this new lens was wonderfully sharp with fast auto focus and the minimum focus distance of around 3 feet made it ideal for flower photography and indeed some of my best flower photographs have been taken with this lens.

Sony 70-300 f4.5-5.6 SSM

Switching camera systems is always stressful and expensive. Sony started putting all of their R&D into their new E mount mirrorless system and their A mount was being neglected so I made the difficult decision and switched to the E mount mirrorless system to be future proof. I sold the A700 and all of my A mount lenses bar the Tamron 90mm f2.8 macro and purchased a Sony A7mk2 and 70-200mm f4 lens. It's a terrific lens but the focal length of my photography was getting shorter every year and I missed the longer length in my lens line up. The problem was there was nothing longer in the E mount for years.

The Covid-19 lock down has given me the chance to think about my photography and it's future direction. I've only been photographing flowers in my garden for the past three months and I felt that I needed to broaden my range of photography to wildlife, nature and sport once the virus has receded and life has got back to some sort of normality. That meant purchasing another super zoom lens.

It's taken a long time for Sony and third party lens makers Sigma and Tamron to supply a good range of lenses for the Sony E mount. Wide angle primes and mid range zooms dominate the lens line up. Sony had brought out the Sony 100-400 (£2,300) but the super zoom range was sadly missing. 

This Spring Sony released the Sony 200-600 f5.6-6.3 G lens (£1,700) to fantastic reviews but when searching Youtube for reviews I stumbled across videos testing the Sigma 150-600 f5.6-6.3 Contemporary lens with the Sigma MC11 (Canon EF - E mount) adapter on E mount mirrorless cameras. My camera is the Sony A6400 APSC mirrorless camera.

The reviews on the Sigma 150-600mm Contemporary lens were excellent for a lens priced at only £749. The MC11 adapter brought the package to £970 and my choice of super zoom lens to buy was made. Is the Sony 200-600 mm a better lens? Yes it is, but for an occasional wildlife photographer like myself the financial saving is significant. 

During testing I've found the Sigma 150-600mm auto focus to be quick and accurate and the images to be sharp if you understand the limits of shooting hand held at 600mm (900mm on my APSC crop sensor camera) There are also two custom mode settings for the auto focus and stabilisation. These can be set to your preferences depending on your type of shooting using the Sigma USB dock which I've also purchased.

Below are my first test shots using my new lens. They were all taken hand held from 150 - 600mm and have had minimal processing. When you consider that the 600mm range is a whopping 900mm on my APSC camera, I'm extremely happy with the image quality and I have a few candidates for club competition through testing alone.

At the moment we're still in semi lock down. Sports are only just re-starting again while many nature reserves are still closed. I'm looking forward to the challenge of wildlife and sports photography that I've been neglecting over the years. It should be fun.

Adendum: Two weeks after purchasing a Canon version of the Sigma 150-600mm Contemporary, Sigma released their first zoom lens for the Sony E mount system and not before time. The Sigma 100-400mm f5-6.3 (£899) is getting excellent reviews on Youtube. Tamron are sure to follow soon.

Lock Down Flowers

It's been a very frustrating 2020 for many Wirral photographers. The New Year brought a constant string of Atlantic storms which hit the coastline hard where I live testing only the bravest of photographers resolve. As soon as Spring arrived, the storms receded and we were hit with a virus from the Far East in the form of Covid-19. 

Of course the virus has caused the closure of every public garden, sporting and social event and has restricted our movements to essential travel only which has been equally frustrating. Wales has closed it's border preventing any landscape photography in the Snowdonia National Park which is only a 2 hours drive away.

As I'm in a vulnerable category for Covid-19 infection due to my age, I've taken the UK Government's lock down advise seriously and diligently to protect the NHS and only ventured out briefly to walk our dog and to shop. For that reason I've had to be content with photographing flowers in my garden as they've emerged in the warm Spring weather.

Tradescantia
Tradescantia

My garden has been given a major makeover which starting last Autumn with the division of established perennials. The work has continued this year with the felling of an ailing tree at the bottom of the garden to let in more light to give existing plants a chance to grow. With more ground water and food available this area has been extensively re-planted with shrubs and woodland plants giving me more subjects to photograph during the year. With nowhere to go the work has taken up most of my free lock down time.

Iris
Iris

I spent the Winter months creating my own textures to use in the post processing of the flowers and I use them whenever one fits the subject as in the Iris above but there are times when I have to resort to using the excellent textures of Kathleen Clemons to get the painterly effect that I love and which is a feature of her beautiful photography. Putting the right texture and flower subject together is the most difficult part of creating textured flowers. 

Arum Lily

As Spring changes into Summer I'm finding new subjects to photograph in the garden almost every day but I'm impatient for the re-opening of my local gardens at Ness Botanic Gardens on the Wirral Peninsula and Bodnant Gardens in Conwy, Wales in July. The seasons are brief and flowers need to be photographed in their peak condition. Miss a week and flowers can quickly go over resulting in a missed opportunity for another 12 months. My aim during the second half of 2020 when released from Covid lock down will be to capture enough quality flower images to keep me busy post processing during the long dark Winter months.

Journey Through My Garden In Infrared

I've been a digital infrared photographer for 15 years and for most of those years the cameras that I've had converted have had the ability to record infrared video but the record button has never been touched. It's not that I'm adverse to shooting video, it's just that I concentrated all of my time to learning how to get the best results from infrared stills.

Before taking up photography 15 years ago my family had to get used to having a Canon camcorder following them around on family days out, holidays and during Christmas. We look back on those short presentations of my two girls growing up from 5 yrs old to teenagers and wonder where the time has gone. Shot on Hi8 tape on "Auto" with wind noise from the built in "Mic" and the background click, click of the auto focus, those short cheesy presentation always bring a smile to our faces no matter how many times they've been viewed.

Photography records a split second moment in time and the results when done well can be very powerful, whereas video records a persons personality and character, the way they walked, spoke and laughed, their interactions with others as well as the clothes they wore and their surroundings.

For Christmas 2019 I bought myself a DJI Ronin SC gimbal to steady my Sony A6400 colour camera with the intention of shooting family videos again of my grandchildren growing up, but this time in 1080p HD and 4k video. For audio I bought a Rode external mic and a dead cat remembering how the wind noise and auto focus noise of old would ruin the finished masterpiece. The full days footage of our extended family's Christmas Day was reduced down to a 10 minute cheesy presentation in HD and is preserved for posterity for my grandchildren to look back on when they're adults.

For a few years I've been thinking of trying some short videos shot in infrared spurred on by watching some excellent footage on Vimeo. The purchase of the gimbal coupled with the right weather conditions this Spring gave me the opportunity to experiment with the 1080p HD video quality of my Sony A6000 720nm wavelength converted camera. Wanting to shoot video in pure monochrome I added a B+W 0.93 filter to the lens allowing me to record in the 830nm wavelength of pure monochrome infrared. 

The finished test video "Journey Through My Garden In Infrared" was shot during the Coronavirus lock down and is available to view on Vimeo. The video is just over 2 minutes long. I'm certainly not a talented videographer and it's difficult to make a trip through my garden look interesting but I'm very pleased with this test of image quality and sharpness of 830nm video. 

The captured footage was processed using Corel Videostudio Ultimate 2020 and the naff music came bundled with the software. The footage in the finished video was recorded at 50fps allowing me to slow down the speed to 25fps and the contrast has been enhanced. Apart from those simple adjustments it was a case of cutting and pasting footage together with transitions linking them together. I'm encouraged enough by the results to find a more interesting and challenging project, perhaps street video, once the Coronavirus crisis is over and Great Britain starts to get back to normal.

Faux Colour Infrared Using Nik Viveza

I've been photographing in digital infrared for 14 years starting with the Sony F717 and an R72 filter progressing to permanently modified Sony A6000 mirrorless cameras in the 720nm standard and 590nm super colour wavelengths of light.

The 720nm standard wavelength of light (being on the edge of the colour spectrum of light visible to the human eye) captures some weak colour in the red and blue colour channels which you can use for faux colour infrared images. The standard practice for faux colour infrared photography has always been to swap the red and blue colours using the "channel mixer" to give your image a blue sky.

Birkenhead Park Boathouse - 720nm infrared channel swapped

The 590nm super colour wavelength of light is closer to the colour spectrum giving you a mix of the colour spectrum and infrared light. As an infrared photographer this gives you more creative options for coloured infrared as you now have some colour in the Red, Yellow, Blue and Cyan channels. You can swap colour channels as before and adjust the hue and saturation of each colour individually to produce a psychedelic world of faux colour.

Bodnant Hall, Wales - 590nm infrared channel swapped

Bodnant Gardens Terrace - 590nm super colour infrared

As you can see from the images above taken with a Sony A6000 720nm standard infrared camera and a Sony A6000 590nm super colour infrared, the latter captures more colour to play with in post production. Can you go further? Yes you can.

Nik Viveza

Last year I stumbled on a Youtube tutorial hosted by the Master of infrared photography Mark Hilliard in the United States on creating faux colour infrared images using Nik Viveza 2. The technique allows you to use the software's U-point technology to selectively colour foliage. Place a control point on the foliage of a tree and you can change the hue, saturation, warmth, brightness to colour the foliage in pastel shades. It works with all wavelengths of infrared except 830nm pure infrared which has no colour recorded in the image to be used by Viveza.

Birkenhead Park Boathouse - 720nm infrared processed using Nik Vivessa2
The photograph above is a standard 720nm infrared image, channel swapped to produce a blue sky and finished using Nik Viveza 2 to selectively colour the foliage. This technique gives the photographer far more options in this wavelength. However, the 590nm super colour wavelength produces far more dramatic results as it has more colour recorded in the infrared image and you can be as bold or as subtle as you wish.

Biddulph Grange - 590nm infrared processed using Nik Vivessa 2
I've only just got started in post processing infrared images using Nik Vivessa 2. The reason I love infrared photography is that it challenges you to push the boundaries and be creative from faux colour to monochrome fine art photography in 830nm pure infrared.

Videography

Before taking up photography I always had a consumer camcorder in my hand recording my family growing up. Christmas, birthdays, Summer day's out and family holidays the camcorder was always in my hand. As young children my two daughters didn't mind having a camcorder pointed at them and sometimes they used it themselves but as they grew into teenager's they naturally started to rebel and the recording became less frequent and eventually stopped altogether.

Looking back now at those short grainy home movies shot in a homely often cheesy style brings a lump to the throat and they are enjoyed and cherished by all of the family. A photograph captures a fleeting moment in time but video captures the personality of those being filmed, how they talked, moved, their sense of humour and their character. As well as recording the innocence and fun of my daughters growing up, older family members who are sadly no longer with us are now on disc. Those recordings are an important family record to show to my grandchildren as they grow up.

The video stopped at about the same time that my interest in photography started. Most of the digital cameras that I've owned during the last 14 years have had the ability to record video but incredibly I've never used it. Cameras nowadays are designed to produce terrific video footage as well as photographs. I've owned cameras producing 1080p HD video and my main camera, the Sony A6400 records excellent 4k video footage as well as 1080p HD in super slow motion. My infrared camera records video in 1080p HD and I can't wait to get arty with infrared video.

I recently received the good news that my fourth grandchild is due in May 2020. By taking photographs of my grandchildren and family and ignoring the video capabilities of these excellent cameras I'm missing out on something important and enjoyable.

My cameras don't have image stabilisation built in and neither do my prime lenses. Camera shake really is a video killer so I took the decision before Christmas to purchase a gimbal to shoot good quality smooth video instead of buying myself another lens.

The DJI Ronin SC gimbal is perfect for the Sony mirrorless system. It was delivered two weeks before Christmas giving me some time to learn how to set it up and use it, balance the camera and shoot some test footage before the big day.

With a cheap Rode external mic on the camera hot shoe I shot video all Christmas Day with my whole family present for dinner. The 4k footage was flawless with the camera in P auto mode and family members old and young are now immortalised in the way they walked, talked, laughed and showed off their personality. The challenge now is to learn again how use new software to put that footage together into a short record of the day. It's going to be fun learning the video side of the camera during 2020.

Photography is still very important and it isn't being put to one side. I'm just adding new skills to my bow and getting more bang for bucks out of the other 50% my cameras.

Samyang 8mm f3.5 Fisheye Lens

I'm always looking for ways in which to help me to be more creative with my photography straight out of camera. This can be done by using a different perspective, using slow shutter speeds, voluntary camera movements, creative blurring, etc. Another way is to use lenses to aid creativity such as the Lensbaby range of "art" lenses.

A lens in my bag that I've used creatively for a number of years now is the Sony "A mount" Samyang 8mm f3.5 fisheye lens. The lens gives a 180-degree field of view and the edges of the frame are distorted, which is handy where exaggerated perspective and an extreme field of view is needed.

The lens is extremely easy to use. There are no electronics in the body so aperture and focus is manual only. Simply set the aperture to f3.5, set the focus distance to 1 meter and everything from two foot to infinity is in sharp focus leaving you free to compose your image and shoot away. A bonus of a fisheye is the ability to capture good images in low light at slow shutter speeds hand held if you are careful. It's a very forgiving lens and a lot of fun to use. Because there are no electronics the lens is cheap and can be bought for around £250 depending on the mount. All of the photographs in this post were taken with the lens.

At the National Waterways Museum at Ellesmere Port, Wirral I had no room to step back to widen the view but the 180-degree view of the fisheye lens allowed me to get a shot and capture something different at the same time.

A fisheye lens lends itself well to architecture where space is tight but also where you want to display the majesty of a building. I've used it to great effect inside a number of impressive buildings.

Liverpool Central Library
Use the camera in portrait mode as with the above photograph of Liverpool Central Library you can capture an 180-degree view of the floor and ceiling in the same shot. Likewise the shot below of the central spiral staircase of the Museum of Liverpool life is accentuated by the distortion created at the edges of the images.

The extreme field of view pushes detail and points of interest into the far distance so getting up extremely close to foreground interest and letting the middle ground fall away into the distance can be effective. Fortunately the minimum shooting distance of this lens is 12 inches which was used in the above photograph. The biggest problem with a fisheye lens is keeping your feet or your shadow out of the shot.

When you do want to show the majesty of a scene then get up high and use the fisheye lens distortion to your advantage as in the above photograph taken from the dome of St Pauls Cathedral in London.

For me the bonus of the Samyang fisheye lenses are their suitability for infrared photography. They produce sharp images with no hotspots. The only problem of course with a lens this wide is keeping flare out of your shot.

The fisheye effect doesn't suit every situation or every photographer but the Samyang fisheye lens is a cheap creative lens to have in your bag. I've now switched from Sony A mount to an E mount mirrorless camera and the first lens I bought was the Samyang 8mm f2.8 fisheye 11 which is even sharper and smaller than the early A mount version used to capture these images.
