Why I always shoot images in RAW file format

Derek Smith • Sep 03, 2021
I always set my cameras to shoot RAW + JPG file format for two main reasons; the first is that I can recover lost detail from the image far easier from a RAW file because the file contains all of the detail from the camera. The second reason is that the micro four thirds sensors on my Olympus cameras are 16 megapixel, or 20 megapixel, a relatively small pixel count these days, a typical JPG image from the 16 megapixel sensor is only around 8 Mb, whereas the RAW file is the full 16 Mb output from the sensor and contains all of the data.

The disadvantages of shooting in RAW are; slower load times in post-processing software, slower write to disc times within the digital camera, the SD card fills up quicker, and any lens corrections will have to be applied in the post-processing software. None of these issues are insurmountable computers have become a lot faster, SD cards are cheaper and available in larger Gb, and have faster write times than ever before, and most post-processing software these days will either have a lens correction for that particular lens, or the corrections can be applied manually.

The images shown are a real world example of what can be obtained from a RAW file, this is an image shot in a shopping arcade, straight from camera the image is very dark and has very little detail. Just 2 minutes post-processing in Skylum Luminar software has brought all the detail out with only 3 sliders, a tweak of Accent, Structure, and adjusting of the Shadows reveals the hidden detail very easily.

Good Morning All Last week at the club we had members giving 15-minute mini lectures on club outings as well as other subjects. There is a report on our website, but it was a very good evening ending in Richard Hildred showing Bromoil prints. This week, Wednesday 6th November Alan Harness will be speaking and showing PDI's, Alan is travelling quite a way to speak to us so hopefully as many members as possible will be there on the night. If you have not entered the PDI of the year, send your entry to Harry as soon as you can please. Today at 1pm we are as a club taking part in the LPA club PDI competition at Nettleham, hopefully we will have a few members attend the competition. Regards Graham

At our meeting last night, members of the Society gave a series of “mini lectures”. The topic for the evening was intended to showcase images from the summer Society outings to the nature reserves at Donna Nook, Chambers Wood, and Kirkby Gravel Pits. Unfortunately, owing to the paucity of wildlife this year at the various nature reserves the wildlife images were short on the ground, members stepped up and produced some exceptional images from over this summer. Dave Turner produced some beautiful monochrome images of grasses, and thistles from Chambers Wood. Tony Gaskins stunned with one of his trademark long exposure seascape images, followed up by atmospheric images of his trip to the isle of Harris, and a beautiful image of a Gannet inflight at Bempton Cliffs. Paul Twomey produced some excellent considered images from a visit to the National Trust properties at Quarry Bank, and Lyme Park in Cheshire. Graham Harrison as the Society President had attended all three outings found the greatest concentration of wildlife at Kirkby Gravel Pits, and this stunning image of mating damsel flies is testament to that. Chris Birchmore treated members to a selection of his images of local churches from the Open Church week, as well as photos from the Heckington Show, and steam road engines at the Driffield Showground. Last, but not least, Richard Hildred passed around some of the prints from the Bromoil Circle box, this heritage photographic print technique creates some exquisite artistic prints. It was fascinating to see the diverse skills of members of the Society, a big thanks to members who participated in the lectures making for a wonderful evening. Thanks also to Dave Mann who tirelessly provides refreshments for our evening meetings.

One of the many things that life has taught me, is to be very wary of Politician's promises; alongside this is a growing skepticism in the ability of Weather Forecasters. Knowing October, I was expecting a cool, perhaps damp day but no indication of the fog at the Coast (according to our esteemed TV forecaster). Heading south over the Wolds and then past Alford the mist was bad, turning into nasty fog patches. Chapel St Leonards, as my destination, was pretty much a white-out in parts. Yet again, I do what most photographers do and adapt as best as possible to the situation. I had committed myself to a walk along the sea front, but in setting off, with the muted colours and absence of people, I thought a moody Black & White set may present itself. I enjoy attempting to visualise a B&W scene, then trying to produce my thought on the monitor with the software. I'm nowhere near as proficient as some, but the fun is in the trying. Armed with the Canon EOS 5D iv and the 24-105 f4 L IS series lens, I shot in Manual mode, setting1/250sec and using the aperture range of f8-f10, letting the camera traverse the ISO scale in Auto ISO. I find Auto ISO a real bonus as I can establish both the depth of field I want, and the time the shutter stays open (despite the light level), to let me hand hold, having confidence that the exposure is maintained as I want, through the Auto ISO. Another clever feature (useful when mist and fog are involved) is the Canon's functionality to alter the EV in Manual mode by reassigning a Fn button, rather than compromising a change in set aperture or shutter speed. I spent about an hour walking round, hardly any people around other than a few hardy walkers taking the air and a lovely lady with a Greyhound. Any day with a camera in hand is a good day, it was also pretty much free until we called in at the Garden Centre on the way home, but that's another story... Don't be put off by the weather, where possible embrace it, there's an image out there somewhere. The visit in the mist showed me low contrast levels, muted colours and how it's nice not to be trapped by people in every scene.

Good Morning All We were away last week staying at Loftus which is about 15 miles north of Whitby. We had some very good weather which was lucky for this time of the year and visited many places on the North Yorkshire coast as well as inland. Last week at the club you watched part two of the N&EMPF Exhibition DVD, I hope you all enjoyed looking at some of the best club photography in the East Midlands. There is a report on our website blog. This coming week, Wednesday 30th, we are holding a series of mini lectures (15 mins) with photo's from this years outings, please let me know ASAP if you would like to take part. Harry is still taking entries for the PDI of the year (PDIOTY). Regards Graham

At our meeting last night we held a showing of the N&EMPF Exhibition Print DVD, as always the standard of entries was of an extremely high standard. The images demonstrated the pinnacle of photographic excellence amazing wildlife images of birds, insects, and I loved the pride of lions gazing at a herd of antelope. The stunning night time images of heritage steam locomotives were very atmospheric. As usual images of sports featured highly, but there seemed to be fewer landscape images this year. For me as a portrait photographer, I was particularly interested in several of the images shown, and wondered if I have sufficient talent to enter next year, this image of a “Beach Maiden” is possibly headed in the right direction. It was a very interesting evening.

Last week at the club we held a print competition, with the categories of "Monochrome" and "Open", there were some very good prints in both subjects and the results are on our website. I would just like to congratulate Paul Gray for first place in the open and Dave Turner for first place in the Monochrome. This week, Wednesday 23rd October, we will be showing the N&EMPF exhibition print DVD with the best prints in the East Midlands. You can also send Harry your PDI of the year entry (PDIOTY) if you wish. Regards Graham

A print competition was held last night with the categories of "Monochrome", and "Open". The judge for the evening was Jorj Malinowski who critiqued the prints in his usual competent, laconic, and humorous style. In the Monochrome section, Dave Turner was placed first with his stunning "Down to Platform 8" taken from the top of the stairs on the London Underground. For the Open section Paul Gray was rightfully awarded first place for his beautiful capture of Gannets taken from a boat off Bempton cliffs. The competition page has been updated with the full results, and the top 3 placed images in each section.

Photography is one of those hobbies where you’re constantly learning whether it’s the details of your camera, or photographic techniques. Incorrect camera settings – How many times have you been on a photo shoot and found that the photos didn’t look great when viewing them on a computer screen? Recently on a photo shoot with a model in a low light situation, I left the ISO at 160, when I should have used an ISO of 400, even though I opened the aperture to f/1.8, the shutter speed was still too low at 1/42, as a result the image appears soft, and more by accident than design the photo does have a certain aesthetic and is usable. Later in the shoot I did notice my mistake and I’ve managed to create some rather lovely images of the young lady. After reviewing my images, I’ve adjusted my camera settings to use Auto ISO with a range of 160 – 3200, and a minimum shutter speed of 1/60 which should overcome any further mistakes. Blown Highlights – This is a common mistake, and one that’s frequently brought up by judges. Photographs of birds with white plumage such as swans, and gannets in bright light can often result in blown highlights which are unrecoverable in post processing. For my portraiture work bright window lighting, open sunlight, or indoor LED lighting can result in blown highlights on the face. With the camera in Aperture Priority mode, the exposure compensation dial is your saviour, I have selected the “Live View Highlights Alert”, otherwise known as the “Blinkies” on my camera. With the correct settings on your camera turning the exposure compensation to a negative value can preserve the highlights as this image of a swan on the boating lake at Cleethorpes illustrates. Dynamic Range – Modern digital cameras have a tremendous range of dynamic range, and a lot of detail can be teased out of the shadows even from a jpg image. However, when shooting a subject against a bright sky often photographers will lose detail in the sky, even where the sky is overcast. To overcome this, use the exposure compensation dial to retain detail in the sky, your subject will appear dark, but lifting the shadows on the subject will recover all the details. This image of the steam locomotive Cranford at Ludborough straight from camera is shot at -2 EV, the sky detail is retained, the detail on the locomotive and train can easily be recovered in post processing. Composition – Possibly I should have listed this at the top of this post, as it’s one of the most important aspects of photography, together with mastering light. Creating a photographic image that tells a story, that impacts the viewer is the key to a successful photograph, and begins even before you have a camera in your hands, ask the questions: What is it you’ve seen? What’s the intent? Can the subject be viewed from another angle? Where is the light falling? For this image of St. Hybalds Church, I wanted to take this photo because of the sunlight falling on the church, and the wispy clouds in the sky. The path from the bottom left of the image leads into the photo, I allowed sufficient room at the top of the church to correct the verticals and converted the image to monochrome as I like the sky details. Cropping slightly into the image removed any distractions at either side of the church. Enjoy your hobby, and keep learning.

The LPA Battles Competition Final for 2024 was held at Nettleham Village Hall near Lincoln on Sunday, 13th October 2023. Heather Burns ( Guild of Photographers, Triple Master Craftsman, Judge, Panel Member ), judged 90 images, from 6 finalist clubs, with over half of the images scoring 17 points or more. Louth tied 4th with Axholme on 277 points, but there's no shame in our positioning in the final, because we were only 12 points behind Cleethorpes in first place on 289 points, therefore I think that we've performed very well as a club. As a group of photographers we are up there with the best in the LPA, what I believe would improve our performance in the 2025 Battles would be to pay more attention to details in our prints. As an example my portrait entry of Pearly Katey, shown here, is a good monochrome portrait of the model taken in a studio. However the large negative space to the right of the model, and the mottled backdrop reduced the score to 18 points. Other criticisms of the submitted prints from all clubs were "too tight" in the frame, and in a similar vein a subject was too close or even under the edge of the frame. Bright areas in backgrounds of the image, or a dark subject on a bright background also had points deducted, an example of this was a monochrome portrait which had a bright white button in the bottom right hand corner, very easily cloned out. The other criticism which is so easy to fix is converging verticals, one club entry was of window cleaners on the the side of an office block, and it was a well seen impactful image, but I think it might have scored more points if the window frames had been edited as verticals. With such a high standard of photography from all the clubs, it's the "impact" of the image that scores highly, and the smallest detail errors that get points deducted.

Good Morning All I spotted this on the North York’s railway, well what else would you call it? Last week at the club Grahame Dunkin gave us an excellent talk on Wales, which in the end covered four years of trips to take photographs. There is a full report on our website blog. Today (Sunday) it is the LPA Battle finals at Nettleham village hall, we have made the finals which is a good club achievement and the event starts at 12.30 and finishes at about 4.30. It would be good if a few members attend and brilliant if a lot of members attend. This week, Wednesday 16th October, at the club we are holding the monthly print competition, withe the categories of "Monochrome" and "Open" judged by Jorj Malinowski. Harry will be pleased if any more members sent some images for the LPA club PDI competition. Does any member object to their monthly and yearly PDI competition entries being used for this competition which Harry might have already? Please let me know if you do. Harry will also take your entries for PDI of the year, all the rules and categories are on our website, you may enter up to six PDI’s in the six subjects with a maximum of three per subject as you may want to enter more in one subject than other subjects. Regards Graham
