CameraBag is a collection of nine photo filters to give the iPhone’s rubbish camera a boost. The application lets you add preset edits to your photos - so you could turn the photo into a moody B&W photo or a warped fisheye lens shot. You either take a picture with the iPhone’s camera from within CameraBag, or choose a photo already in your library.
To see how a photo will look with a particular filter, you load the photo and then tap the name of the current filter at the top to bring up a list of all filters, or you can swipe your finger left or right on the screen to scroll to the previous or next filter.
CameraBag’s filters are varied and high-quality, and offer hours of fun. To get a sense of what they can do, check out the CameraBag Flickr group, which has loads of images from CameraBag users.
