iPhone Photo Apps
With the release of the iTunes App Store last year, naturally there have been lots of applications submitted and available for purchase that deal with Photos. It only make sense, after all, but there are two that I'm aware of that do something that makes them stand out from the crowd. (NOTE: I have not used either as I do not have an iPhone and refuse to pay to upgrade my iPod Touch to the 2.0 firmware).
iFOTOMO is a viewer for Flickr photos that presents them in a mosaic. However, the user can pan and zoom, and upon zooming make the zoomed image the new mosaic target. It is a very interesting concept, and adds something new to the many Flickr viewers out there, at least that I've seen.
The other app that I've seen that I would definitely purchase, is Nick Campbell's ShakeItPhoto. What is interesting about this, is that it emulates an "old school" Polaroid camera in that upon snapping a photo, with the iPhone's camera, the processing is designed to take a little while to finish, but, it speeds up when you shake your phone—just like a Polaroid. You can see it in action here, and see a ton of examples on Nick's ShakeItPhoto photo blog.
