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. In fact, 16-
bits/channel color mode is invoked automatically when:
importing a raw image from Raw Studio.
opening a 16-bit Microsoft HD photo.
PhotoPlus also lets you manually choose modes:
