iRAW is a manual and automatic camera app that stores all photos as lossless, compressed TIFF files, which you can upload to Flickr and DropBox or send as email attachments. You can also store them as JPEGs to the photo gallery.
iRAW helps you achieve the most accurate and most artistic photos that an iPhone can currently provide. In manual mode, you can use a slider to control shutter speed. You change the ISO with a slider or a button. You can use 31 levels of digital zoom (with pinch zoom). iRAW supports bracketing. There is an optional 2-second delay.
There is a live histogram to help you take better photos.
There is a live level so help you take perfectly horizontal shots, and it can be calibrated.
You can take full resolution photos and (somewhat sharper) one-quarter resolution photos.
There are numerous live filters that can be used to provide character to your shots, including monochrome, negative, color negative, and various color filters.
Photos produced by iRAW are technically not "raw", but they are the highest quality images that Apple provides (they're never compressed). However once Apple makes true RAW quality available, iRAW will support it. Until then, iRAW provides Apple's noise-reduced photos.
Enhanced the live histogram to include histograms for red, green, and blue components in addition to intensity.
