What you observe is a limited dynamic range (DR) of digitals, which holds true for any DSLRs. Some DSLRs with larger sensors do often have wider DR, e.g., EOS FF ones, though.
In the same principle which is actually physics, the K100D seems to have slightly wider DR too, than the K10D, e.g., for the reproduction of more shadow details.
Originally posted by Pelham I have been having a problem when shooting very high contrast shots with my K10D. An example would be taking a picture inside a room with available light and there is a small window with extrememly bright light at the window.. the net result is a band of either green or magenta bleeding out from the over exposed high contrast part of the picture. Sometimes this happens when I am shooting simply outside in the shade, and I am exposed properly for the shade, but there is very bright areas in the background.. I may then get green or magenta streaks virtually crossing the picture from these bright background areas.. Very disturbing to say the least!
Any ideas what might be happening?
