Unfortunatly exiftools doesn’t give helpful hints: there’s also Average Black Level : 2048 2048 2048 2048 But this results in massive clipping of the dark areas, losing a whole bunch of details. I also checked the raw.pixls.us <http://raw.pixls.us/> image (https://raw.pixls.us/getfile.php/130/nice/Canon%20-%20EOS%207D%20-%20sRAW1%20(mRAW)%20(3:2).CR2) - unfortunately far away from being norm lit Setting black points 0-3 to about 118 -125 seems to give a most neutral result (based on the black keyboard ) And it’s also fine for the OPs image, so maybe its a good initial value for tweaking ...
