What are some really cool iphone apps for photography?

Like there's one where it shows two of you, like a mirror effect?
can you just like give me a list? AND THEY SHOULD BE FREE?

Camera+

There are some features that the basic camera doesn't allow that are interesting, like adding a timer and taking a photo. Camera+ has some incredible tools to help you filter, focus and add clarity to the photos you're taking, as well as the ability to straighten them out.It's a pro toolset built for the amateur!

Grid Lens

Grid Lens allows you to take collections of photos and put them together in a single image. You can select and customize a layout, then take each of the photos by clicking on the spot, and then save, share or email the finished product.

ColorSplash

ColorSplash allows you to remove color from portions of a photo you've taken. The app is incredibly easy to use - just expand the photo and drag your finger where you want to wipe away the color.

Over

Did you ever have a photo that begged a caption? That's what Over is for… Providing a really cool navigation wheel that allows you to add a fancy caption to your photo in a minutes.

Snapseed

Snapseed offers some interesting filters and standard editing tools for your image. The finite controls are impressive and the usability is pretty innovative.

Blender

Blender does just what it says… Allowing the ability to blend multiple images together. Here's a blend of Chicago… Driving into the city and looking down at it.

Aviary

Recommended by Nat Finn, I didn't even realize that Aviary had iOS applications. The irony is that I'm enjoying the iPhone application much better than the web version!
