Imaged with Canon EOS 20Da and 5D in the dark and in temperature of -5°C, cameras were cooled for 2 hours with out lenses. Camera settings were 1600 ISO speed and no dark subtraction, exposure time was 30 seconds. Images were converted from RAW to 16-bit TIFF in Digital Photo Professional v2.0.3.7 adjusting brightness up to 100 and contrast to 100 ( which no one does with normal images! ) white balance was set to daylight. Here are full size 300X200 pixel cuts from the middle of the images.
