Is there a program to compare or overlay pictures to tell the differences.
I have a retaining wall that is gradually spreading, and a few years ago I put in two screws, one on each side, and have been taking photos in three dimensions ever since. It is difficult to compare these photos manually, even though I have tried to take them from the same distance each time. Thanks for any advice.
