Photomerge (also called gigapan / gigastitch)

Download the three image sets below and use automation to create 3 different kinds of photomerge. See what shapes are most successful. Merge all the layers together and use the color sample tool and the paintbucket to create a matching background for your merges. Finally, use adjustment layers to make the resulting images more dramatic.

Automation VIA action

Record an action that applies several adjustments and changes the size of an image. Use your action to perform a batch operation on one of the photosets you downloaded.


Use your phone to create an image set that will work for a photomerge. Bring your image set to class somehow and use actions to make all the photos smaller. Complete the photomerge in class next tuesday.

Notes: Android allows you to shoot gigapans from within your phone, and iPhone has an HDR setting. Google photo sphere is an app for iphone and android which lets you create gigapans. Experiment with these tools and see what you can make.
