Rotating
There are many reasons that you might want or need to rotate an image. If you have a scanned picture or a digital camera image that should be vertical but opens as a horizontally oriented picture, rotating it 90 degrees corrects the problem. This is a common occurrence when you use a scanner because it's usually quicker to scan with the picture horizontal, regardless of its normal orientation (see Figure 4.5).

Figure 4.7. You can even rotate by fractions of a degree.

Try it YourselfStraightening the HorizonUsing the Arbitrary Rotation dialog box is an easy way to correct a picture that needs to be straightened. The picture in Figure 4.8 was shot just as the photographer was about to be blown off the boardwalk. Fortunately, fixing tilted horizons is an easy problem for Photoshop. Find this photo at the website and work along. It's called oldorchardbeach.jpg. Figure 4.8. Oops, the horizon's not supposed to slant downhill.![]()
