The Crop and Straighten Photos command is a nifty way to quickly straighten and make separate image files out of one image. For example, you have a photograph of two people standing side-by-side, and you want a separate image of each person. Or you have a scanned image that wasn't quite straight on the platten. The Crop and Straighten Photos command works best when the images in the document are separated by some space. When you apply the command to an image, it looks for areas to divide based on shifts in color; no selection is required.
