Working with Layers in Photoshop 7: Part 2
By Gary David Bouton
Using the Liquify Command
In the world of Photoshop, there's something called "modes". It won't make a lot of sense right now if you're just beginning, but Photoshop can eventually (and potentially) blend the visual information (the image area) on one layer with the underlying layer(s). The way in which the data (image area) is blended is called a mode. There are 22 layer modes (modes into which you subject an entire layer's contents) and 23 painting modes (all the layer modes plus the Behind mode, which enables you to (apparently) paint on the back of a layer, thus preserving the image data on the front of the layer.
The following section runs down what different modes do so you can make intelligent choices on work of your own, and explains why I ask you to choose certain modes in the picnic image for stuff.

Well, we've run out of pixels again for the month. Stay tuned right here, though, since there's more fun... oops, research, coming up. Next month I'll show you how to make your own brush tip, how to make grass grow and a lot of other neat tricks.
