I've recently started doing timelapse clips using my Canon 60D and interval shots. Because this often involves pointing the camera at large areas of sky and using small apertures to obtain slow shutter speeds, dust bunnies have suddenly become very noticable - maybe ten or a dozen faint but obvious spots on each image. I searched the internet on how to assess the extent of the problem and discovered how to shoot an out-of-focus area of sky and then use auto-levels on the image to show up the spots. SHOCK! It looked like a passing car had run through a puddle of dirty water and showered my sen -
I shot some images yesterday, you all know the one - bright blue sky over a yellow field of oil seed rape. In the blue sky area I found a couple of dust spots. In successive images they were in different places on the frame. In ten years of using Olympus interchangeable lens digital cameras I have never had a dust spot, so I am none too pleased with the Sony sealed water and dust proof camera having them after only three months use... Sealing is good if you seal the dust out, but not if you seal it in.

Watch out for this gotcha! It caught me out - so a warning, just something to bear in mind. I was using a Fuji X-E1 and 18-55mm lens but it will probably be a risk with any mirrorless camera especially with wide-angle lenses that have a rear element that comes close to the sensor. I took some photographs on a misty morning and when I processed them I discovered large shadowy smudges down one side easily visible with the large areas of flat light grey. I thought it was dust (but looked a bit odd) or a mark on the sensor but I could not see it with magnification and cleaning achieved nothing -
Is it worth submitting images where there is obvious dust on the subject (or surroundings)? For example on a dirty streetsign or around and in a reflection on still water. Cleaning it up would take more time than would be worthwhile - but submitting uncleaned images could well fall foul of QC who might interpret the visible specks as sensor dust. Especially if they were outwith the focal plane and blurred. Any opinions? -
Hi, My name is Mo, I'm an amateur, and the only camera I have is a Canon 1000D (Rebel XS). So I uploaded 15 photos. I know it wasn't a wise idea to upload 15 as the first attempt, obviously all of them got failed, because the person who inspect them probably couldn't distinguish between dust and birds, and so he probably just found some "Dirt or dust or other blemishes" on my (lucky me) first photo, quoted that on it, and failed all 15 with no other comments. COME ON! It's probably not a very good photo I know, but is it a good reason to fail all other photos even though there are not even a
