How to create a photo panorama from multiple images using Photoshop’s hidden Photomerge feature. Neat.
Believe it or not, a lot of people don’t know that Photoshop can automatically stitch photos together to create a panorama. If you continue reading, then I’m guessing you fall into the “believe it” category. Honestly, when I show people where this feature is and that it’s really called Photomerge instead of Create Panorama, they’re always amazed.
well… not quite hidden.
RTFM
