Straighten a Crooked Image with the Crop Tool in Photoshop or Elements

Click inside the crop rectangle, and drag it so that either the top or bottom middle control handle is right on top of the horizon line. In this image, we are using the true horizon line, but in some photos you might not have a true horizon line. In those cases, you can use any line that should be horizontal-- it may be a roofline, sidewalk, fence, or something else.
