Tools and Techniques for Removing Backgrounds

Knock it Out!

Previously, I wrote an article on removing backgrounds from images. That article was more of an overview of various approaches that were available rather than specific techniques. It served to show you that there's more than one way to get the job done, and there's never a one-size-fits-all magic formula. While the subject for this article is similar, this time, I'd like to get specific with the various techniques and tools that are available to you, and hopefully help you understand why and when you should use one method over another. I'm sure I couldn't possibly cover every possible approach for every type of image, so if you have a favorite method of your own, you're encouraged to share your favorite techniques in the discussion forum.

An Overview of Corel KnockOut
Formerly known as Ultimatte KnockOut, this product was once only available for the Macintosh platform. It was recently purchased by Corel and ported to the Windows platform. It's a standalone product that offers superior masking capabilities in a surprisingly simple interface. Click the link to check out my overview and examples.
