Photoshop Tutorial - For Advanced Beginners and Intermediate Users

There was a time when vignettes were "undesirable" in photographs. Vignettes
in the real world are created by such things as wide angle lenses, lens elements,
polarizing filters, lens hoods, etc...etc

Recently I have noticed this effect being created artificially in magazine, on the web,
and in wedding albums. It offers a nice touch to just about any image, and takes it one step further.

I'll show you how to create two distinct types of vignettes that you can use to add
some style, and take you one step closer to becoming a true "Photoshoptic Surgeon"
