I was looking for an easy way to create diptychs and the like from iPhoto, without resorting to Photoshop. Then I discovered Posterino. With this, I can easily pull photos from iPhoto (or Aperture), create layouts, and even export to Flickr in one go.
Just for a test, I threw in some of my photos from my Interbike/CrossVegas trip in September, 2009. I really liked some of the shots I got, and it was also really the last hurrah for trusty Canon S410. Several weeks later, it would be sustain serious water damage in Portland. Of course, now it takes some pretty interesting photos, as well…
