Using the Crop command, you can remove the areas that fall outside of the current selection. When you crop to a selection boundary, Photoshop Elements trims the image to the bounding box that contains the selection. (Irregularly shaped selections, such as those made by using the Lasso tool, are cropped to a rectangular bounding box that contains the selection.) If you use the Crop command without first making a selection, Photoshop Elements trims the image by 50 pixels from each visible edge.
