Why Remove Noise?
Paul Malley • 5 January 2024
I'm sure many of us remember the days of being frightened to put a roll of 35mm or 120 Roll Film in a Camera, that had anything above 400ISO on the side of the box? if you did, you were pretty much guaranteed to get your pictures back from Boots, 14 days later with grain the size of golf balls, hiding whatever was meant to be the focal point! Nowadays, advances in Sensor technology across Camera Manufacturers, reduces this level of electronic interference we call Noise to a minimum where it is not obtrusive (I will happily run at 10000ISO before I seek a flash gun). For the first time however, I decided to actively 'add' grain in a final output image; personally, I would offer an opinion that the subject needs to lend itself to such an activity. Here, I went out at 5pm under Pawnshop Passage in Louth during a recent heavy rain downpour. The low lighting, rain and time of day lent itself to using f4 Aperture (I couldn't set up a tripod in the Passageway as numerous people were taking cover, or transiting through). Hand held at 1/60Sec in auto-ISO gave 10000. With such a large aperture, Depth of Field was shallow. The conversion to B&W was done via my favoured Affinity Program, a lot of contrast was added, no enhancing shadow, but it still lacked a bit of bite. The final input was to add grain with a sliding scale to give a 'bitty' feel. No output sharpening was undertaken. In this instance, the image appeals to me as the feel and emotion is enhanced by the addition of the grain. A positive rather than negative addition.

Good Afternoon, All, Last week at the club we held our monthly print competition, with the categories of "Mono" and "Open", judged by Diane Seddon. It was a very good evening with Diane critiquing our prints with helpful comments on how we could improve our images as well as praise. The results are on our website but well done to David Whitehouse for best print in the mono and Dave Turner for best print in the open. This week, Wednesday 22nd October, we go back in time to before the millennium with transparency slides to be shown by Tony Gaskins, Chris Birchmore, Richard Hildred and myself. You can start sending Harry your entries for the PDI of the year, all the rules etc are on our website, but the important thing is you can enter any PDI's as long as they have never been in a PDI of the year before. There are six subjects and an overall max of six PDI's, no more than three per subject. Regards Graham
A print competition was held last night with the categories of; "Monochrome" and "Open". Diane Seddon from Cleethorpes Camera Club was the judge for the evening, Diane is very skilled, and thorough in her judging, providing useful insight, and critique of the prints. Many of her comments centered around the best cropping of an image to optimise the subject within the frame, and giving the subject "room to breathe" in the framing. Congratulations to David Whitehouse placed first in the "Monochrome" category, with his superb rendering of a face sculpture, and Dave Turner placed first in the "Open" category with his stunning print of the sunrise over Whitby Harbour. Thanks to Diane Seddon for a great evening, and as she remarked at the end of the competition all the prints were of an extremely high standard. The Competition Page has been updated with the highest placed images, but currently the score sheets for the competition are unavailable.
Good Morning All Last week Dave Bennett came to the club again, it has been a while since we have seen his photography but well worth the wait. Dave's photographs were excellent and his story telling along with AV's made it a very good night. This week, Wednesday 15th October, we are holding a print competition, with the categories of "Mono" and "Open", our judge for the evening will be Diane Seddon AFIAP CPAGB BPE3* she is well qualified to judge our prints. The following week we are going to try a retro night again, with Transparencies taken prior to the year 2000, please let me know if you want to take part and have a time slot allotted, time will depend on the numbers wanting to take part. Regards Graham
Last night Dave Bennett came to the club to show us AV's and narrate other sets of photographs on a theme. Dave started with photos along the Humber and then carried on the evening with AV's on nature, flowers and transport as well as talks and photographs showing us Grimsby docks including detailed photographs of fish smoking and engineering. Dave's photography is of a very high standard with strong colours, lot's of use of depth of field and they tell a story. A great night, thank you Dave.
Good Morning All Last week at the club we held a local PDI competition with a category of "5 Minutes From Your Home", we had some very good entries in each category with myself, and Dave Turner judging on the night. All the results are on our website, but well done to Derek for his mobile phone picture of a remembrance seat in Horncastle and Harry for his hellebores in the "Open" category. This week, Wednesday 8th October, Dave Bennett is coming to the club to show us what he has been taking lately, Dave does quite a bit of AV so as usual it will be a very good night. A reminder, send your print titles for the next print competition to Dave Turner by midnight Wednesday and bring your prints in this Wednesday night as well please. If you have any more N&EMPF Exhibition PDI entries send them to me by midnight tomorrow (Monday) please. Regards Graham
Our PDI "Local" competition was held last night, with the categories of "5 Minutes From Your Home", and "Open". Dave Turner, one of our members began the evening with judging the "Open" category, always a difficult category in my opinion because of the variety of subjects entered into the competition. Dave had previewed the images on his home computer, and had notes on each of the images, he provided excellent feedback on each image. After the break, Graham Harrison began judging the "5 Minutes From Your Home" category, this was a very unusual subject category which stretched the creative ingenuity of members, and it was particularly interesting to see what members had submitted. Graham judged the entries very fairly, and provided very good critique of the images. The standard of images submitted was high, which makes judging a competition such as this difficult, and as always is subjective, but a big thank you to both judges, it was an interesting evening. The first placed images, from each category are shown on this post, "At the Going Down of the Sun" by Derek Smith, "5 minutes from your home", and "Hellebores" by Harry Kerman in the "Open" category. The website Competition Page has been updated with the top three placed images, and the scoresheets.
Good Morning All Last week at the club member Tony Gaskins gave us an excellent presentation of his recent trip to Kenya on safari. Tony showed us the animals and birds he had encountered on his trip. It was an evening of excellent wildlife photography as well as a very informative talk, thank you Tony. There is also a report on our website blog. This week, Wednesday 1st October, we are holding a local PDI competition, with the subject categories of "5 Minutes From Your Home" and "Open", Dave Turner has kindly offered to judge the Open with myself the subject, and you have until midnight tonight to enter. Dave Turner is also asking members to send him the titles of their prints for the next print competition, the categories for this are "Mono" and "Open". Regards Graham
Our member, Tony Gaskins presented us with an illustrated talk on his visit to the Kenya game reserves last night. Tony's talk was perfectly timed, and his description of the trip held our attention throughout the evening, the images he captured were indeed stunning. The variety of wildlife he captured with his camera were amazing, all of the photos of birds were incredible, and the fact that they didn't fly off like they do here in the UK. On Lake Naivasha Tony captured a sequence of a fish eagle swooping down to catch a fish, just look at the way those deadly talons are outstretched to capture the fish. The lodge Tony stayed in at Tsavo West was beside a watering hole, look at this capture of a Kirk's Dik Dik, taken from the balcony of the lodge. Images of Hippopotamus, Lions, Impala, Ostrich, Giraffe and Zebra kept us enthralled through the evening. Thank you and well done Tony for an interesting evening.
Good Evening All A little late as just got back late this afternoon from the golfing trip, I didn't take my camera other than phone as I wouldn't have really had time but there was some interesting wildlife about including Swallowtail butterflies which was a first for me. Last week you had the monthly PDI competition, Long Exposures and Open, Derek has done a blog on our website and the competition page has all the results. Some excellent photography on show judging by the top places. This week, Wednesday 24th September, we have member Tony Gaskins entertaining us with one of his talks, Tony is well travelled so as usual it will be an excellent evening of photography. Regards Graham
Last week we held our first PDI competition after the summer break, and what a superb evening it was. There were some excellent images submitted into the competition, and over half of the submitted entries were "held back" for awarding higher points, Tony Houlden was the judge for the evening. This week, Wednesday 24th September, Tony Gaskin will be giving an illustrated talk on his recent visit to the Maasai Mara game reserve in Kenya, it will be an interesting evening, with some stunning photography. Harry will be taking entries for our next PDI competition, with the categories of "Local 5 minutes From Your House", (in this case the "Local" applies to your house, not the 25 miles from Louth) and "Open". Harry is also taking entries for the LPA Competition, he's looking for 6 entries in this competition, from each member. I've been out, and about as usual, this photo is of an abandoned garage forecourt on the road to Spilsby.
