PseudoGrey (1999)
- PaulHoule 5y agoI remember using this method circa 1990 to get more grey levels out of vga which only got 6 bits of color depth. I would draw quantum wave functions and stuff like that and found the posterization unacceptable unless I used tricks to expand the color depth. I found dithering was a really good answer that made perfect-seeming images in screen. These days what I notice about ‘deep color’ is that the viewing environment makes a big difference in what you can see, both for a screen where the environment is secondary and for prints where the environment provides all the light you work with. I am always looking at photo prints I make with my son and thinking really hard about questions like: should I print this lighter or just exhibit the print in a place with more light?
