Teeth Whitening in Photoshop
I have seen questions arise on occasion in Adobe's Photoshop User to User Forum from Photoshop users wanting to know how to use Photoshop to whiten a person's teeth. There are several approaches, one common technique simply making careful use of the Sponge Tool to desaturate the offending colors. But, one of my favorite techniques is one which I learned from a Denny Tang tutorial that no longer seems to be on his website. More complicated than some approaches, making use of a saturation adjustment layer and blending mode changes, it seems to give what I feel is a more natural looking result, and is what I used to create the image below that I gave to my personal dentist. The tutorial itself is provided in PDF format and may be found here: Teeth Whitening Tutorial by Denny Tang. Thanks Denny!
