For many people, GIMP is a program for processing photographs. GIMP is actually much more than that, but photo processing is, indeed, one of its most valuable uses. This is why the first manipulations we demonstrated in 1.3 Working with Images dealt mainly with photographs and why we devote two chapters to the subject—this one and Chapter 5. The main difference between these two chapters is that in this chapter we process only one photograph at a time, whereas in Chapter 5 we’ll process several simultaneously to create composite images.
