First of all... hello everyone! this is my first post. I need a program to do the following thing: I have thousands of pictures, some of them have 4:3 aspect ratio, others have 3:2 aspect ratio, and a few of them non standar aspect ratios. I need all of them to be the same aspect ratio (4:3), adding horizontal black bands if needed but never cropping the picture. Can this be done? I can't find this option in the programs I use. Thanks!
