I'm putting together a series of images, and I want the horizon line to be a constant from image to image, though they were not that way in the original files. I'm assuming that I should go with the picture that has the smallest distance from the bottom of the picture and then crop the others so the distance appears to be the same in them as well. But is there a way to make that a simple process? Here are two images to help understand what I am doing.
There are probably other ways to do this but here is a method that may or may not work for you. Basically I am using guides to help me line up the new crop to the desired crop. See if you like it.
