I found this really cool app for the iPhone that lets you combine multiple photos into one image. The app is called Diptic, and it’s available in the iTunes app store for only $.99.
Diptic provides and intuitive interface that allows you to select a layout from the generous selection. You can then fill each space on the layout with an image from your camera roll, or you can take a new photo. The images can be sized, moved around, and even enhanced within the app with the toolset provided.
If you’re an iPhone photographer, be sure to take a look at Diptic! And no, I’m not affiliated and I don’t get paid to say this.
