I looked closely at some images that had a white wall and could see the pink in the lower RH corner even at ISO 12800. I had noticed something not quite right with the right top and bottom corners, but now that I've looked, it is AMP glow. Supposedly, that went away with the move to CMOS. It was quite noticible with the CCD sensors and long exposures, but with ISO 12800 and a 1/40 sec exposure, I'm suprised to see it.
Here is a image. Note, it was in my laundry room at night with lights off and the lighting was about -1 LV, and was darker on the right side due to light coming down a hall at right angles and the doorway shading a room that was almost totally dark anyway.
All my low light test images had a slight pink tinge in the lower RH corner, and to some extent in the upper RH corner. The one below shows it the most.
I wonder if this will be a big problem for astronomers, I would certainly think so.
