[QUOTE="Horoscope Fish, post: 377704, member: 13090"] This is a common misunderstanding. 12 bits is not 50% more than 8 bits. We're talking about Binary so the calculations need be done in Binary. The actual math looks like this... 1 2 4 8 16 32 64 128 = 8-bit. If we add those up (1 + 2 + 4 + 8 ... + 128) we get 255. Including zero that gives us 256 values. This is per color-channel so to get the total number of possible colors we multiply again: 256 x 256 x 256 = 16.7 million. To get 14-bit we have to continue on the Binary scale for fourteen iterations: 1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 = 14 bit. Add those up and you get 16,383. Including zero that gives us 16,384 values. This too is per color-channel so once again we multiply it out for each of three color channels: Red, Blue and Green.
