A 16-bit-per-channel image provides finer distinctions in color, but it can have twice the file size of an 8-bit-per-channel image. In addition, only the following Photoshop tools and commands are available for 16-bit-per-channel images:
• The marquee, lasso, crop, measure, zoom, hand, pen, eyedropper, history brush, slice, color sampler, clone stamp tools, healing brush tool, and patch tool, as well as the pen and shape tools (for drawing work paths only).
• The Duplicate, Feather, Modify, Levels, Auto Levels, Auto Contrast, Auto Color, Curves, Histogram, Hue/Saturation, Brightness/Contrast, Color Balance, Equalize, Invert, Channel Mixer, Gradient Map, Image Size, Canvas Size, Transform Selection, and Rotate Canvas commands, and a limited set of filters. (See "Using filters" on page 321.)
To take full advantage of Photoshop features, you can convert a 16-bit-per-channel image to an 8-bit-per-channel image.
