Image Models (Colour Modes)

Image Models (Colour Modes)


RGB (Red, Green, Blue)

·         RGB is the primary image mode for graphics. However it is important we remain aware of other image modes.

These additional modes include:

CMYK (Cyan, Magenta, Yellow, Key or Black)

·         It is faster to work with CMYK, however RGB creates a smaller file size making it perfect for the web.

·         CMYK appears ‘dulled out’ when printed, as it doesn’t use light when its printed out.

Gray Scale

·         Gray scale images include actual shades of grey.

·         You can make coloured images gray scale, but you cannot do the reverse.

·         You CAN turn a gray scale picture into a DUOTONE image (two colours)

BITMAP

·         BITMAP images are made up of black and white pixels only with no shades of grey or colour included.
