120 Color and Grayscale
If you no longer need to work at a high level of detail (16 Bits/channel), you can
convert your image to 8-bit mode which results in smaller file sizes and allows
you to take advantage of PhotoPlus's range of special filter effects.
To switch from 16-bits/channel to 8-bits/channel working:
From the Image menu, select Color Mode, and pick an 8-bits/channel
option from the submenu.
To check which mode is currently set, the Title bar shows the mode
after the file name, e.g. CRW_4832.CRW @ 20%, 3088 x 2056, RGB 16
Bits/Channel.
Choosing colors
Foreground and background colors
At any given time, PhotoPlus allows you to work with just two colors—a
foreground color and a background color. These are always visible as two
swatches on the Color tab indicated opposite.
The foreground color is set to green (RGB 63:173:73) and the background color
to black.
The Color tab makes it possible to set the working color model before color
selection: RGB (Red, Green, Blue); CMYK (Cyan, Magenta, Yellow, Black) ;
HSB sliders (Hue, Saturation, Brightness); HSL sliders (Hue, Saturation,
Lightness); HSL Color Wheel; HSL Color Box; or Grayscale.
