A dry plate photographer needs a way to use an iPhone's flash as a manually controlled light source with adjustable duration and intensity for portraiture, but existing camera/flashlight apps lack the precise timing controls required for this creative application.

iPhone's built-in camera and flashlight lack manual controls for flash duration and intensity needed for off-camera lighting in analog photography; no specialized app provides a simple metered flash tool.

App Concept

FlashMeter Pro

FlashMeter Pro turns an iPhone into a customizable handheld flash unit for analog and long-exposure photographers. Users can precisely set flash duration (from 1/1000s to several seconds) and brightness, trigger via timer or remote, and save presets for different emulsions and setups. It fills the gap between basic phone flashlights and expensive dedicated flash meters.

Key Features

Adjustable flash duration from milliseconds to seconds
Intensity slider for fine-tuning brightness
Presets for common emulsions and exposure times
Remote trigger support or timed delay for self-portraits

Target Users: Analog and experimental photographers, particularly those using slow emulsions like dry plates or large format, who need a portable, programmable light source.

Revenue Model: $4.99 one-time purchase or freemium with pro presets/remote trigger as in-app purchase.
