Former cinematographer David Bross has released DIGILOG, a free iPhone camera app that reconstructs images from raw sensor data using a film-inspired color science pipeline. The app offers a Kodak 500T-inspired look and ARRI Rec.709 profile, with open-gate recording capabilities in ProRes 422 or H.264 starting from the iPhone SE 3rd generation. DIGILOG positions itself not as a filter or LUT overlay but as a fundamental reimagining of the iPhone’s image processing chain. Rather than applying a look to Apple’s processed output, the app intercepts the linear scene signal immediately after debayering and constructs the entire image from that point forward. This approach, according to David Bross, translates his DaVinci Resolve color grading workflow directly into the iOS camera environment to produce ready-to-use images that require minimal post-production intervention. The developer’s background in cinematography and color science led him to create DCTLs for Resolve before transitioning into furniture design and woodworking. Despite leaving film sets, his ambition to build custom camera systems persisted, with DIGILOG serving as the initial step toward that larger goal. Building images from the ground up DIGILOG’s technical approach distinguishes it from typical camera apps that apply effects to finished images. The app takes control after Apple’s native debayering process, implementing custom de-linearization, gamma curves, and color adjustments before final output. This method allows the app to bypass certain iOS restrictions, enabling open-gate recording formats that Apple’s native camera typically reserves for higher-end devices. The app currently supports ProRes 422 recording in open-gate mode across compatible...
