Diptic is a flexible way to assemble several photos into a single image. It has a lot of layouts, and it will output a high resolution image.
One thing I like to use Diptic for is to show alternate views of a single place, event, or concept. In this case, I was shooting the Embarcadero Center in San Francisco with Hipstamatic. The tile pattern and the sculpture are iconic and recognizable to anybody who has spent much time there. The escalator and the seated person were also in the area, but are not as immediately recognizable. By using Diptic to assemble all the images together, they all become part of the story and the viewer is helped to see the images as four parts of the same place.
I also use Diptic in conjunction with some other apps to make surreal images with interesting patterns. I’ll post about that later in the week.
