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.

Good Morning All We have just come back from a week in Northumberland, staying at Newbiggin by the sea. I took plenty of coastal photographs including many of the area's wildlife. Last week while I was away it was the monthly print competition. There is a blog on the website as well as all the results on the competition page. I really just need to congratulate Dave Turner who won both the subject and Open competition. I am not sure if Wednesday night's studio evening is going ahead yet but will let you know. Entries for the local competition, Local Events and Open need to be sent to Harry by midnight next Sunday. We judge this competition in house; I am happy to judge one subject if anyone else would like to judge the other subject? Regards Graham

We held a print competition at our meeting last night with the categories of "Curves" and "Open". Our judge for the evening was the very competent, and accomplished Diane Seddon. Diane gave excellent critique of the prints, and one of the main themes that Diane highlighted was the presentation of the prints, siting print sizes, mount sizes, mount colours, and more thoughtful cropping of images selected for printing. Definitely food for thought, and addressing those issues will improve members points scoring in future competitions. All the prints submitted into this competition were of a very high standard, however, it was Dave Turner who swept the board with 1st, and 2nd placing in the "Open" category, and 1st, 2nd, and 3rd placing in the "Curves" category, it was a well deserved placing with some stunning prints. The Competition page of our website has been updated with the full results. Thanks to Diane Seddon for judging the competition, and Dave Mann for the refreshments.

Dave Turner, and I attended the LPA Fosters Challenge at Nettleham. The judge for the competition was Sue Wilson from Clay Cross. Axholme took first place with 19 points, Grimsby 2nd, and Cleethorpes 3rd. Louth was awarded 13 points, consisting of: Damselflies Mating – Graham Harrison 4pt Saltwick Bay – Tony Gaskins 4pt The Thinker – Keith Rossington 3pt Muted Swan – Harry Kerman 1pt Pier Number 9 – Dave Turner 1pt It was an interesting competition with some amazing images, a big thank you to Dave Turner for selecting the prints and submitting our entry into the competition.

Good Morning All Last week at the club member Chris Birchmore took us back in time with old photographs and a very interesting talk on one of Louth's old shops Platts stores. Platts stayed traditional for many years but as like most of the old shops eventually disappeared along with it's upside down sign. There is a blog on our website as well to look at. This week, Wednesday 16th April, we will hold our Print competition with the categories of "Curves" and "Open" to be judged by Diane Seddon of Cleethorpes. Harry is also now taking entries for the local PDI competition, with the categories of "Local Events" and "Open". Regards Graham

Our member Chris Birchmore gave an illustrated talk last night titled "The Shopkeeper and his Assistant". Chris related details of his family origins, and family history in Louth, in particular his connection with Platts Provision Store in Eastgate. It was a very interesting talk which evoked many memories with those members who had themselves been raised in Louth. Many thanks Chris, the preparation, and talk was excellent.

Good Morning All With all this warm weather some insects are out and about to photograph, I took this photograph in our garden with a Sigma 105mm lens to get close in on the bee. It is another month now, so you need to think about your "Prime Time" project, if you are taking part. Last week at the club Brian McCarthy FRPS showed us his personal journey in photography, Brian takes most of his photographs in his shed building models with lighting and creating photographs that most of us would never think of. This week, Wednesday 9th April, our member Chris Birchmore who will be presenting a historical talk entitled "The Shopkeeper and His Assistant" specifically talking about a relatives memories of working for Mr. Platt the Shopkeeper. For those who have prints for the next competition, with the categories of "Curves and Open", you need to send Dave Turner a list of your entries and bring the prints in this week. Regards Graham

Good morning, All Last week we held our spring committee meeting, we discussed many topics including the new program which will be available to you all soon and did some preparation for the AGM. This week, Wednesday 2nd April, Brian McCarthy FRPS will be coming along to show us some more of his work. Brian is an ex-member of our club but has more recently been a member of Grimsby Photographic Society. You can also now start sending your print titles for the Curves and Open competition to Dave Turner. Regards Graham

This year’s project is “Prime Time”, simply one photo taken each month with the same prime lens. The resulting 12 images will be shown to members on our “Project Night” next January. Why a prime lens? Well, a lens with a single focal length, a prime lens, provides a photographer with creative options. Composition of the image when using a lens such as this is essential, a photographer must choose a subject and move around that subject to obtain the photo. Every photographer should have a prime lens in their bag, and it doesn't need to be expensive. I recently switched from Fuji cameras to the Olympus / OM Systems camera ecosystem. Now, I use the OM Systems OM-1 camera with two zoom lenses and three f/1.8 prime lenses. For the “Prime Time” project, I'll creatively use the Olympus 45mm (90mm full-frame equivalent) f/1.8 lens, this lens is typically employed for portraits. This tiny, sharp lens, which captures beautiful portraits, was bought used for £149 from a reputable dealer.

Good Morning All Last week at the club we held our PDI competition for March, with the categories of "Including the Moon" and "Open" judged by Mike Bennett. It was a very good night with some excellent photographs entered in the competitions, especially the Open. There were three twenty points awarded out of twenty photographs in each subject, Tony Gaskins had a very good night winning both the subject and the Open. All the results are on our website under competitions. The NEMPF PDI Inter - club competition went ahead recently, not so many clubs entered this year, I think there were only three LPA clubs who had entered, Louth came 11th, I'll leave it there. Thank you to Harry for organising our entry. This week, Wednesday 26th March it is a committee meeting for committee members only to attend. To keep you busy though you could prepare your prints for the next print competition, with the categories of "Curves" and "Open". Regards Graham

At our meeting last night we held our Projected Digital Image (PDI) competition with the categories of "Including the Moon", and "Open". The judge for the evening was Mike Bennett. Mike skillfully judged the 33 submitted entries in the "Open" category, providing excellent feedback on the various images. After the break Mike appraised the 18 images in the "Including the Moon" category, this had been a difficult subject for members to photograph, and was also challenging for the judge. Congratulations to Tony Gaskins for his first placements with "Moonbell, Mablethorpe" in the "Including the Moon" category, and "Dawn, Whitby" in the "Open" category. As is usual, the Competition page of the website has been updated with the top three placements in each category, and full results. Many thanks to Mike Bennett for judging the competition, and Dave Mann for providing the refreshments.
