Converting an image to another mode
Before converting images, it's best to do the following: - Do as much editing as possible in the image's original mode (usually RGB from most scanners or digital cameras, or CMYK from traditional drum scanners or if imported from a Scitex system).
- Save a backup copy before converting. Be sure to save a copy of your image that includes all layers in order to edit the original version of the image after the conversion.
- Flatten the file before converting it. The interaction of colors between layer blending modes will change when the mode changes.
To convert an image to another mode: Choose Image > Mode and the mode you want from the submenu. Modes not available for the active image appear dimmed in the menu. Images are flattened when converted to Multichannel, Bitmap, or Indexed Color mode, because these modes do not support layers.
