I am rotating photos in photoshop CS, but would like to then fill out the corners so it still looks like the picture is a rectangle (the edges are various shades of grey). I saw a youtube video where the guy took a photograph out of a plan window, and in photoshop straightened the horizon and then did something to get photoshop to make up for the pixels in the corners so it looked like a complete photo. I'm pretty sure he didn't just crop the white bits out! Hopefully someone can help me. Thanks
