Ok, this app seems very interesting to me. It seems to be able to almost (and i mean almost) sorta grab RAWs kinda.
PRO 645 intercepts the camera data after it’s been initially processed (demosaiced and with processing parameters such as white balance and sharpening applied), but before the phone compresses it. This file can be be saved as a TIFF (presumably 8-bit), alongside a JPEG version with whichever of the app’s image manipulations you’ve chosen to apply. These JPEGs are also much less compressed than the iPhone’s default compression, which is usually the starting point for most apps (equivalent to the maximum quality option in Photoshop, the developer claims).
