Computational-Photography Pipeline Editor That Lets Pixel And Modern Android Owners Edit The In-Camera JPEG Recipe Instead Of Starting From Hideous RAW
Pixel and most modern Android cameras apply a heavy multi-frame computational pipeline (HDR+, Night Sight, deep-fusion-equivalents) before the in-camera JPEG. The user-facing options are 'finished JPEG' or 'raw DNG that looks ghastly until you do hours of work'. There's a clear and recurring HN/photo-forum complaint: people want to start from the JPEG-recipe and adjust a few parameters, not redo the whole pipeline by hand. The opportunity is a desktop+mobile editor that reads metadata, reverses the in-camera pipeline as far as it can, and presents the JPEG-as-recipe with sliders.
The hard bit is reverse-engineering enough of HDR+ metadata to expose useful sliders. You won't get all of it. Ship the 5 sliders that solve 80% of complaints (white balance, sky tone, skin tone, tone curve, sharpness) and call it a day. Don't try to be Lightroom for computational pipelines.

The whole RAW-editor industry was built when 'RAW' meant Bayer-grid sensor output. On computational-pipeline phones, 'RAW' is an orphan format the camera vendor barely supports. Nobody has built the editor that admits this and treats the JPEG-recipe as the source of truth.
