Doing the Big Flip
With Photoshop, you can rotate, horizontally flip, or vertically flip an entire image. The commands that perform such transformations are in the Image>Rotate Canvas menu shown in Figure 18-1. Most of the commands shown in Figure 18-1 are pretty self-explanatory, but I quickly run down the Image>Rotate Canvas menu:Rotate an image to stand it on its head by choosing 180.
Choose 90 CW or 90 CCW to rotate the image one quarter turn clockwise or counterclockwise, respectively.
Rotate an image a specific number of degrees clockwise or counterclockwise by choosing Arbitrary.
Flip the image so that left becomes right and right becomes left by choosing Flip Canvas Horizontal.
Choose Flip Canvas Vertical to flip the image upside down.

| Tip | If you want to skew, distort, or add perspec-tive to an entire image, you have to perform the transformations by linking all the layers together and then performing a layer transformation. For details on how to link layers together, take a look at the “Linking layers” sidebar in this technique. |
