I need some clarification on color modes available in Photo. Namely the RGB/16, is it integer or float and if float then how can I input colors below 0 or above 1? And then there is RGB/32 HDR, is it integer or float, and if float, how can I input colors below 0 and above 1? Also are these modes linear or gamma corrected? Another thing is the export to Open EXR (when I choose More... options). I can choose from 16 bit half and 32 bit float, what is 16 bit half, is it integer or float? One more thing: I have some HDR and EXR files, which I'm certain contain values above 1 (32-bit float), but Photo shows them as 1 (ie. 255 in each RGB channel in the Info panel). How to show the true value, if it's above 1 or below 0?
Hi, In Photoshop there has always been the automatic ability to drag a Marquee around an area of an image in a layer to isolate it. After dragging a marquee around the area, pressing a cursor key would immediately snap the marquee around the area snugly (Even anti-aliased as you'd expect). This then allows you constrain your painting to be within the marquee selected area. I believe you can also do this in Gimp also by using the Float option (It's been a while since I used it). Thanks, Jay.
