Filters for Photoshop is a powerful function that allows one to manipulate images easily.
I have used them to create borders around pictures. To create interesting backgrounds. Or to take a picture that just did not turn out the way I expected it to; I created an interesting background to create a neat one of a kind scrapbook page.
Before correcting color on an image that was scanned. The first thing I do is use the dust and scratches filter.
You can find a wealth of free and to buy filters on the web.
Has anyone else used filters?
