Hi, this is probably the dumbest question I've ever asked on a forum but here it goes. It seems we had 8-bit, 12-bit/14-bit (DSLR RAW images) and 32-bit floating EXR images....but is there any reason to see anything else beyond this? Is it tecnically or inevitable that there will be 64bit images in the future? Just…
16-bit images can already have 4294967296 different shades of color per channel. 64-bit image would have 18446744073709551616 per channel, and as most monitors can't really display all the different colors of 16-bit images, 64-bit images would really just be a waste of disk space at the moment. Maybe when monitors have 1…
Yeah, in Photoshop change Image/Mode to 32 bits per channel, and you got yourself a 128-bit image. (32 bits * 4 channels) I don't know if we will ever use them for games, but apparently the extra bits are used for storing intensity and other information: http://en.wikipedia.org/wiki/Deep_color
higher bit depths are for post processing bc you will reduce the quality of the image in the process and therefore you need the extra head room. Maybe this could apply to video games in the future if more realtime post processing comes to use. HDR cubemaps already need a higher bit depth. So we'll see ...
