Color and Grayscale 119
Color modes
PhotoPlus operates in several color modes to let you work in standard and
higher levels of color or tonal detail—these are 8-bits/channel RGB (or 8-
bits/channel Grayscale) and the more detailed 16-bits/channel RGB (or 16-
bits/channel Grayscale). Editing in 8 bits/channel mode will use 256 levels per
color channel, as opposed to 16-bits/channel, which uses 65,536 levels per
channel.
As a rule of thumb, use 16-bit working for "as-your-eyes-see-it" image accuracy.
If you work with 16-bit images, you'll probably want to benefit from the
optimum color or tonal information throughout your project.
PhotoPlus also lets you manually choose modes:
