What's the best Android app for manual camera controls and RAW photo capture?

ProCam X is well-suited for photographers seeking manual control over their smartphone camera. The app delivers extensive manual settings including ISO, shutter speed, white balance, and focus adjustments, allowing users to fine-tune their shots beyond what standard camera apps offer. A key feature is the RAW image capture capability, which preserves more image data for professional editing workflows. The interface includes a histogram display for exposure monitoring and manual focus peaking to ensure critical sharpness. Users report the manual controls work reliably across various Android devices, though some note the learning curve can be steep for beginners. The app supports multiple aspect ratios and resolution settings, making it versatile for different shooting scenarios from landscape photography to detailed macro work. One limitation mentioned in reviews is that some advanced features require additional in-app purchases. The exposure compensation controls are particularly useful for challenging lighting conditions where automatic modes often fail. While the interface isn't the most intuitive initially, once mastered it provides quick access to essential photographic controls that serious mobile photographers appreciate.
