Thinking Photography
Derek Smith • 10 January 2024
I don’t know about anyone else, but I’ve had a good week, been out with my camera, and taken some interesting photos.
As is usual for me I’ve been watching YouTube videos to learn more about photography. One of these videos by James Popsys discusses “The Exposure Myth in Photography”, looking at the postproduction of his images. Basically, his premise is that photography is an art form, and the purpose of a photograph is to draw the viewers eye into the subject of an image. Now, how many times have we heard a competition judge say, “it’s a great photo, but what am I looking at?”, James takes the view that in postproduction either the shadows can be deepened, or the highlights blown to direct the viewers eye to the subject. The video can be watched here: https://youtu.be/hH9VBrx3rnY?si=W9RV9ww9fl9ec9gC
The second video that made me think discussed the “Exposure Triangle” regarding ISO, what I didn’t appreciate was that the “Base ISO” of a camera is derived from the sensor, your camera will have a base ISO typically in the range of 80-200 ISO. When the ISO is raised the digital image amplification takes place in the processor after the image is captured. Now, many of you may have heard an audio hiss from an audio system, and with no audio input the hiss will increase as the amplifier volume is increased, this can be likened to ISO in photography, only instead of hearing the noise it can be visualised in our images, mainly in the shadows and out of focus parts of the image.
Modern cameras now are mostly ISO invariant, in that any ISO value can be used with very little degradation of our images. To underscore this point, it was interesting to read Paul Malley’s post, where he was adding noise in the editing software to create the atmosphere in the image.
To test the ISO limit of your camera I would suggest a simple test, take a photo of a high contrast subject, a label on a bottle or a tinned product, use a bright aperture such that the background is blurred, start at ISO 1600, then ISO 3200, and ISO 6400 see how much noise is generated in the shadows / background blur, this will give you assurance that higher ISO levels can be used without degrading an image. This image of a washing up liquid bottle was taken at ISO 10000.
I know that my camera can be used comfortably at ISO 6400, without degrading the image quality, this is helpful in that I can choose an ideal aperture / shutter speed combination, finally selecting the ISO to provide the correct exposure. This is different to the previously held wisdom of choosing the lowest ISO first. In variable light I find it useful to use Auto ISO, with a range of 160 – 6400 ISO, and minimum shutter speed of 1/125, when using Aperture Priority I can comfortably set my required aperture, and just ignore the ISO, it makes shooting worry free. Knowledge is power!!
Images featured here, the singer, and night shot both taken at ISO 6400, the washing up liquid at ISO 10000, and “Coffee Girl” more conventionally at ISO 400.

Our highlight competition, Print Of The Year (POTY) competition was held last night, with our judge Grahame Dunkin giving his experienced critique on the excellent images submitted. Congratulations to Dave Turner for his Monochrome image of the year: West Pier Watchtower - Whitby, and Graham Harrison for his Colour image: Hairy Shield Bug.

Good Morning All Last week we went to have a look at the Lancaster sculpture at Norton Disney, it is open for visitors at certain times and although work is still ongoing the main Lancaster is finished and a car park in place. The sculpture is full size weighing 100 tons and honours WW2 RAF crews. Last week at the club Derek Smith ran an editing night, members were asked to bring their laptops in and Derek gave us all an SD card with some images to edit and information regarding the free editing software. A different and interesting night and hopefully we all learnt something and anyone new to photography would have learnt quite a lot. Thank you Derek for running the evening. This week, Wednesday 11th February, we have one of the clubs yearly highlights, the Print Of The Year (POTY) competition to be judged by Grahame Dunkin, all the entries are now in and you should have checked the scoresheets to make sure yours are included. Dave Turner is also asking for prints to enter into the Foster Challenge and LPA Print Battles. He will ask to use prints that are in the print of the year but if you have any prints that you think would be good to enter in the two competitions please bring them and hand them into Dave Turner. The following week we are having an evening collecting everything in for our exhibition at the Louth museum, if you can sort out any prints especially local prints that could go into our exhibition please bring them in on the 18th February. Regards Graham

Last Sunday I was in Stockton on Tees working with Izzy, a favourite model of mine she enjoys cosplay, that’s dressing up as a character from Marvel, Hasbro, or film titles. This photo is of Fey, a woodland sprite, pictured against a woodland backdrop that I bought for the photoshoot. I stayed overnight at a Premier Inn, and in the morning drove to Staithes, as I had always wanted to visit this fishing village, Staithes in the February rain wasn’t much fun, and the tide was out, but I did manage to take a few photos, and I captured one for the “Water” project so I was pleased with that. I was quite surprised how vibrant the colours were in the drizzle, and misty light. Driving back over the North Yorkshire Moors in rain, and fog, didn’t allow for much photography either. Yesterday, walking along the harbour front in Bridlington the high tide, and strong winds had thrown lots of debris onto the promenade, seaweed, nets, tree branches, and cuttlefish kept council workmen busy clearing up the mess. With the right clothing, and a weatherproof camera photography can still be enjoyed even in poor conditions.

A photo editing workshop was held last night, with members bringing in their laptops, and post processing sample images. Members were able to practice processing bracketed, and focus stacked images. Simple editing tasks of cloning unwanted items from images, cropping, and resizing of images were shown. The excellent FastStone photo viewer, and editor was able to accomplish most tasks apart from developing of RAW images, this free software is a “must have” for those with Windows computers. The Affinity photo editor has now been acquired by Canva, and the changes applied by Canva have made the software very confusing to use, and on my 14” Lenovo Thinkpad, it was very difficult to view the master layer to apply adjustments. PhotoScape X is a simplistic photo editor, for all that the software was easy to use, and the RAW processing was seamless. It was an interesting evening, and hopefully members will have attained some new skills in post processing, some of the images edited are shown here.

Good morning All I did manage to get to visit Gibraltar Point last week, very few birds to photograph at this time of year but I took a few and a Grey Squirrel. Last week member Dave Mann showed us photographs from his visit to Beamish, it's a great day out and Dave went round most of it and showed us some photographs from the new 1950's town as well as the farm, pit village, town and trains. Thank you Dave, and Harry for helping out with refreshments. This week, Wednesday 4th February, Derek is running an editing night, he has sent us all information on what we could download, if you have a laptop remember to bring it along. Print of the year is fast approaching, if you are entering make sure you send Dave Turner a list of your entries with which subject they are in and bring your prints along this week. Regards Graham

Fed up with watching the rain coming down, I set out yesterday into the rain to Normanby Hall to try and get a photo for the “Water Project”, I have one potentially good image, but I always like to see if I can get something better. My OM Systems OM-1 camera, and 12-40mm Pro lens are weatherproof, but obviously I wasn’t, but really lovely to get out.

Last night Dave Mann gave an excellent talk on his visit to Beamish in May last year. Dave explored much more of the Beamish site than when I visited in April last year, Dave mentioned the difficulties of getting on some of the vintage transport around the site, I experienced the same during my visit. It's a fascinating historic working museum and well recommended for a visit. Many thanks Dave for an entertaining evening.

Good Morning All Last week at the club we had our yearly project night, last year it was one photograph a month with the same focal length, there is a full report on the evening on our blog page, but four members did last year's project with newer member Sam Collet showing photographs at the club for the first time, some excellent photographs taken in Japan. It would be good if a few more members took part this year, just one photograph a month with the subject being water. Attached is my January photograph from last year, it would work for this years project as well. This week, Wednesday 28th January, our catering manager Dave Mann will be having a week off and showing some of his photographs. His presentation will be a mixed bag of photographs. Don't forget to send Dave Turner an email with your titles for the print of the year. Entries will need bringing in on the 4th February. Regards Graham

We held our "Project Night" last night, the theme being "Prime Time", one photo each month taken over the previous 12 months, using the same focal length "prime" lens. Myself, Harry Kerman, Keith Rossington, and Graham Harrison, had each completed the project and were able to show their results as projected images at the meeting. The results of the project were very interesting, seeing how each photographer had approached the theme, and their interpretation of the project. I have posted here one image from each photographer. The evening was rounded off by one of our newer members, Sam Collett, displaying some of his images taken on a visit to Japan, his wildlife photography was stunning in detail, and quality, well done Sam.

Good morning All Last week at the club we held our monthly competition, a PDI, with the categories of "Insects" and "Open". There was a good level of entries and some excellent photography. The competition was judged by Colin Lusby of NELPS Photographic Society. The "Open" category was won by Dave Turner with an excellent landscape of Llanberis, and I managed a first place in the subject competition with a Willow Emerald Damselfly, still quite rare but I photographed this one at Bressingham Gardens Norfolk. The results and photographs are on are website under competitions. This week, Wednesday 21st January, is our project night, only four members took part, hopefully more will take part this year. The subject was "Prime Time", one photograph a month with the same focal length lens. To finish the evening, Paul Twomey is showing his mini lecture that he missed last time, and newer member Sam Collett is showing some of his work. The new project subject is Water, one photograph a month including water. There is plenty of water about at the moment, the rivers are flowing well for a start. Dave Turner will now accept your titles for Print of the year, the same subjects as the PDI of the year but with the addition of Best mono in competition as well. This is chosen by the judge from any mono print in the six subjects. Regards Graham
