Best Camera [iTunes link] is a collaboration between professional photographer Chase Jarvis and iPhone dev firm Übermind. The app gets its name from Jarvis's book "The Best Camera is The One That's With You," a collection of photos taken all over the world by Jarvis with his iPhone.
The US$2.99 app features 14 useful filters and effects that can be stacked; in other words, you can take a photo with the iPhone camera, then apply several filters and/or effects before sharing your handiwork. The filters and effects are on a side-scrolling "dock" at the bottom of the screen, and you apply them by simply tapping on the icons. Sharing includes saving the photo on your iPhone camera roll, sending it out via email, or blasting it to your Facebook or Twitter account.
There's also one more place to share your photo. While filters and effects are nothing new, Jarvis has created a community at thebestcamera.com where photos that have been submitted are displayed on a constantly changing photo wall. These photos are also viewable in the app itself, and by tapping a photo in either location, you can view information about the photographer. On the website, the information also includes a list of the filers or effects that were used on the original photo so you can re-create photos that you find fascinating.
