As you ve seen in previous chapters, the application of such fundamental procedures as using layers during the editing process helps to keep an image dynamic. As you work, you can make changes to the image, or even just a portion of the image, one step at a time, until the results are satisfactory. In this chapter, you ll examine Photoshop s capability to take a step backward as well as forward. In this respect, I like to think of Photoshop as the bachelor s software : you never have to make a commitment ”that is, until you finally settle down and publish your work.
Photoshop takes the concept of bachelor s software to the max with the extreme flexibility of its History palette. The History palette is Photoshop s answer to the concept of multiple undos. Whereas some programs provide a system of undoing operations backward in sequence, Photoshop s interactive History palette features both sequential and nonlinear editing.
This chapter will explore Photoshop s undo and History features. In addition, Hands On 3 , Painting, Paths, and History, immediately following this chapter, will put you through the moves using the information covered in Chapter 9, Drawing Paths, Chapter 10, Creating and Applying Color, and this chapter.
In this chapter, you ll learn about:
Undoing what you ve done
Using Photoshop s Time Machine
Working with snapshots
Editing history
