At the WWDC26 Camera and Photo Technologies Group Lab (session 8018, ~29:55 to 32:46), the panel explained why ProRAW can produce 48 MP output from Quad Bayer sensors while native Bayer RAW is limited to the binned resolution. ProRAW is already demosaiced and linearized, and may incorporate Photonic Engine multi-frame processing. The native RAW path exposes the binned Bayer result. A true full-resolution RAW output would be Quad Bayer, not conventional Bayer, and supporting it properly needs a decoding path around it. The panel suggested filing Feedback Assistant requests if developers need this, so I filed FB25352517. My use case is computational photography that wants minimally processed sensor-domain samples on purpose — its own multi-frame alignment, denoising, HDR fusion, motion rejection, and super-resolution. Adobe Project Indigo is a public example of that kind of pipeline. It captures RAW bursts and uses measured sub-pixel variation between frames to reconstruct detail. Processed 48 MP photos and ProRAW don't cover that. They've already been through Apple's reconstruction or demosaic. Is filing enhancement requests still the intended path for a supported full-resolution Quad Bayer RAW or mosaic capture path? If so, what would make these reports more useful — mosaic metadata, DNG representation, CIRAWFilter support, AVCaptureDevice.Format capability discovery, something else?
