Working with Layers in Photoshop 7: Part 6
By Gary David Bouton
This marks the last installment in a series of columns on Graphics.com adapted from my latest book, Inside Adobe Photoshop 7. You can actively participate using Photoshop, and the image files I've supplied, by clicking on the links throughout. This installment won't make much sense unless you've worked through the first five installments. I hope you'll like this series enough to consider buying the book. :)
This month we'll start with a model of a glass stein I rendered, complete with partial transparency, using Caligari trueSpace. This modeling program has two features (besides the rendering quality) that make it an assignment-saver for Photoshop work. First, trueSpace enables me to render the stein (in this example) to any dimension (any reasonable dimension!), so I could render the somewhat diminutive stein practically swallowed by a large background specifically, the same dimensions as the picnic picture you've been working on in previous installments.
The other feature? It renders alpha channels. An alpha channel can describe the shape and opacity of any object in the scene and Photoshop can load channels as selections. So let's see how a stein is added to the table in the scene, and then how to tonally balance the stein.
