Technique 25: Painting Back in Time
Using the History palette
Painting to a previous history state
Only with a time machine or with Photoshop can you paint backward through history. Thanks to the powerful History palette, you can select a previous history state and use either the History Brush or Art History Brush to stroke away the image’s current state and reveal the past history state.
This technique uses a simple example to show you how you can paint backward in time. First, I give you a quick look at the History palette just to show you what’s available there and how to use it. Then, you apply a filter to an image and use the History Brush to remove the effects of the filter. Using the History Brush is interesting and easy.
