Above displays the different colour adjustment model in use on photoshop (Adobe). The first left is in RGB colour, second in CMYK, bottom left is in greyscale and the bottom right is a bitmap.
Here they are presented in a grid made on Indesign. A frame was made and then duplicated to form the four square patter. Then in each I imported a different psd file.
The RGB file was the one originally sourced from online.
When converted to CMYK the deepness and vividness of the colour range lessons, as most visible on the grass sections. This is the colour range in which most printers print however.
The grey scale image uses black, white and grey variations to achieve the right balance.
However in the bitmap, just black and white are used, and the size and density of circles dictates the colour it produces. This is normally used in graphics that are used in print (Newspapers).
