i took some pictures last night, and noticed a few pixels that were white, and a couple that were red. i checked the rest of the pictures, and only one red one showed up in all of them. the white ones werent in the first few shots i took, but showed up in later shots, and werent in the same place for each shot. im pretty sure the red one is a stuck pixel since it shows in all the pictures, but what about the white ones? they werent in all the photos, and they werent in the same spots every time. i checked some randon photos beginning with the first ones i took with my camera, all the way up to the most recent. photos i took a few days ago dont have any of these pixel problems, so this apparently just happened in the last day or 2. what could be causing this, and is there a way to fix it myself? fixing them in post isnt a problem, but i can see where its going to get annoying if i have to fix every shot i take. my camera is insured (Rebel XT), so should i take it back and get a new one, just deal with the 1 pixel thats constant, or try some sort of fix myself if its possible?
