Photographers shooting in raw format struggle to accurately expose images because camera histograms and zebras only reflect JPEG data, not the raw sensor data, leading to blown highlights or underexposed shots.

Cameras do not provide a practical way to evaluate raw exposure in real-time; histograms and zebras are based on JPEG conversion, which underrepresents recovery potential.

Implied Software Gaps

A tool that displays raw channel exposure data in real-time on the camera or tethering device

App Concept

RawExposure Pro

A camera-tethered or in-camera app that overlays raw histograms and zebras on the viewfinder, simulating raw-channel exposure. Uses sensor data to show highlight and shadow clipping thresholds for red, green, and blue channels. Works with mirrorless and DSLR via HDMI or Wi-Fi tethering.

Key Features

Real-time raw channel histogram overlay (R, G, B, luminance)
Raw-specific zebra pattern highlighting blown highlights in each channel
Exposure simulation with user-adjustable recovery curve preview
Compatibility with major camera brands via tethering (USB, Wi-Fi, HDMI)

Target Users: Professional and advanced amateur photographers who shoot raw and need precise exposure control, especially in high dynamic range scenarios.

Revenue Model: $49 one-time purchase or $19.99/year subscription for firmware updates and new camera support
