RGB (Red, Green, Blue) are the three main colours of the colour model and this is used for television s.. CMYK (Cyan, Magenta, Yellow, Black) when you mix the RGB together it then makes the colours in the middle which are CMYK ( Cyan, Magenta, Yellow, Black) and is used for print work.



• Resolution
resolution is the quality of the image. the higher the resolution the clearer the image is. the lower the resolution the less clearer the image is. but it depends on what you do with the image.

• Vector Images: file formats and uses - eps, wmf, fla, svg, ai
vector images are illustrated images made by the computer by using mathematics to create the image by useing paths and points to map out the image.

ai (Artificial intelligence) is the intelligence exhibited by machines or software. http://en.wikipedia.org/wiki/Artificial_intelligence

• Cross-platform Images: format and uses - pdf
Cross platform images are used for creating electronic documents to be delivered over the internet and to other online services.

• Compression - lossy and lossless
lossless images are images compressed and restored to their original quality but take up more memory on the computer.
A lossy image is an image compressed and then restored but you loose part of the image and the quality is not as good. but takes up less memory and space on your computer.
