Capuring Flats
Posted: Fri Sep 15, 2023 6:42 pm
Robin,
I've been using various versions of 4.1 as they have been released and the capture flats utility has these small spikes at 25 and 75% that give me saturation warnings. In some of the previous versions they were bigger and, at one point, they were every 5%. I do not see these when shooting darks or lights. Only when shooting flats so it's not a light leak. Just to verify, I took a flashlight last night out in the dark and shined it all over my imaging train watching the histogram to verify that do not have a light leak.
The first image is what I normally see on the latest 4.1 build and the second is what I see when I run a focus routine.
The flats work when I take them but wonder what I can do to get rid of the saturation warnings. I can adjust the exposure up or down and it will always tell me I have pixels too low, too high, or both. I never saw this behavior in 4.0 with the same gear.
