Underwater Photoshop

  • RGB is the color mode we use everyday for RGB devices such as our screens, cameras, scanners etc. There are also different flavours of this color mode.
  • CMYK is the mode that relates to color printing with inks e.g. in magazines where tiny dots of cyan, magenta, yellow or black are laid down.
  • Lab mode consists of lightness, 'A color' that is green/red and 'B color' which is blue/yellow channels, this is a useful mode to use when you want to enhance details without altering color (by editing in the lightness channel alone).
  • Greyscale is a single black channel for monochromatic images.
