Crop an image
You can crop an image to improve its composition or change its aspect ratio. For example, you
can change an image’s aspect ratio from 4 x 6 to 3 x 5.
Before Crop adjustment After Crop adjustment
There are two methods for cropping an image: you can use the Crop tool to manually crop the
image, or you can use the Crop adjustment controls. The method you choose is determined by
the level of precision you require.
Crop an image using the Crop tool
Cropping an image with the Crop tool is the easiest method. You simply select the Crop tool
and drag a rectangle over your image to exclude the unwanted areas. The Crop HUD appears,
providing additional controls for setting the aspect ratio of the image and displaying cropping
guides to help you visually align the composition of the image according to the rule of thirds.
