As long as you??™re careful not to save over the original file, you also never have
to damage or change the original image.
In this chapter, we??™ll learn how to do the simplest and most common kinds of photo editing.
This is the place to turn to for day-to-day corrections??”simple things you can do to your images
without learning a whole lot about the art and science of image editing. For more sophisticated
things you can do to edit your images, check out Chapters 14, 15, and 16, which get into the
topic a little deeper.
How Much PC You Need
You??™re probably expecting me to tell you that you should have the fastest PC you can afford??”a
10GHz Quad Core with a terabyte of memory sounds just about right. Aside from the fact that
you can??™t buy a computer like that quite yet, you really don??™t need that much speed. To be
perfectly honest, you should work with the fastest PC you can afford. Photo editing, especially
with high-megapixel images, is a horsepower-intensive task. The more computer you have
pushing pixels around, the more fun you??™ll have. A slow PC might frustrate you because editing
operations will be sluggish, and it??™ll even take a while to redraw the screen. But you can make so
with a lot less than the state of the art.
