Backgrounds for my Powerpoint presentation.

[Shaun]

Constructive criticism here: the only one that'll really work is background six. All of the others have way too much contrast and that will make the text very hard to read in many cases. Use similar colours and don't have too much of a difference in brightness.

Edit: Eight, nine and ten are a bit better but seven suffers from too much contrast. Try and spend a bit more time on it. Try and blur them with a Photoshop filter.
