Attractive backgrounds to any graphics, banners or ads are relatively important. Getting the correct theme, whether it’s an abstract art, vector, or texture pattern, it somehow makes the entire artwork looks more interesting.

Some might not have noticed the great roles background images have played. For instance, forumites uses cool design background before messages in their forum signatures; some product graphic advertisements uses light subtle background to help create focus point; your website and desktop need nice backdrops too. Sometimes when I get a little limited by the amount of content I can insert onto an ad design, I’ll paint a light background behind it so the entire creative don’t look so empty.

Here’s 40 really nice abstract and background design Photoshop tutorials you might want to take a look at. It’s probably not about getting the exact effect they’ve got, but to pickup the technique and see how you can advance from there.
