I would like to request a linear scene-referred preview stream for Bayer RAW workflows via AVCaptureVideoDataOutput or AVCaptureVideoPreviewLayer, without tone mapping, computational processing, or a baked-in rendered look. This is particularly important for third-party camera apps built around Bayer RAW workflows, including my app, Lampa Camera. In other words, it would be great to have a preview mode that closely matches the CIRAWFilter output for a Bayer DNG with the following configuration: rawFilter.baselineExposure = 0.0 rawFilter.shadowBias = 0.0 rawFilter.boostAmount = 0.0 rawFilter.localToneMapAmount = 0.0 Currently, the live preview comes from the processed camera feed. As a result, the viewfinder can differ noticeably from the final RAW-converted image in exposure, dynamic range, contrast, and sharpness. A Bayer RAW-compatible linear preview mode would make it possible to provide a reliable what-you-see-is-what-you-get shooting experience for RAW-based camera apps. Would Apple consider exposing such a preview mode in AVFoundation? Related Feedback Assistant report: FB22660803
