Improving your photo's composition
Understanding the histogram
Making advanced photo adjustments
After you've done the best you can to optimize the use of available light and selectively focus to enhance the photo's composition, you might think, "Just take the picture, and you're done."

Covering them all in this book is impossible, so I concentrate on iPhoto '09, which comes with every new Mac or can be purchased separately.
To effectively use the power of the editing techniques available in iPhoto '09, you need to understand the type of editing you must do and how to do it.

Often, capturing a scene is so immediate that you whip out your iPhone and snap a picture without thinking about composition. This chapter covers iPhoto correction tools that might help you clean up those hurried shots.
Detailed descriptions of the interplay of light, sensors, and electronics can easily become complex, so I keep things as simple as possible in this chapter. For more on how to use iPhoto to edit ...
