Lightprint helps photographers and video creators save lighting setups they need to repeat before shooting with a mirrorless, film, cinema camera, or manual camera app. Use the live camera meter to estimate EV, exposure settings, Kelvin, tint, and estimated lux. Lock ISO, aperture, or shutter, then let Lightprint calculate the missing value. For video, store FPS and shutter angle in project presets and see an estimated ND stop guide. Save each setup as a Light Recipe with location, camera, lens, film stock or picture profile, notes, thumbnail, measured values, and recommended target settings. Use Match Score to compare a saved recipe against the live camera reading when you return to the same room, desk, cafe, studio, or product setup. Lightprint includes reflected and diffuser-assisted reading modes, correction EV calibration, device-specific default correction, project presets, CSV export, and 4:5 or 9:16 recipe exports. Free users can measure light, estimate exposure and white balance, and save up to 5 light recipes. Lightprint Pro is a one-time lifetime unlock for unlimited recipes, Match Score, 4:5 and 9:16 PNG recipe exports, project presets, video notes, correction profiles, and CSV export. Lightprint is built for repeatable lighting recipes, not legal lux certification, professional color science, CRI, TLCI, SSI, or flash metering.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Version 1.1.0 makes metering and lighting recreation more stable and repeatable. • Improved metering stability and accuracy through multi-sample analysis and outlier rejection. Stability and EV spread are now visible when capturing. • Match Score now evaluates exposure, color temperature, tint, and reference confidence separately. • New Guided Recreate walks you through capturing a stable Match sample and recommends the exposure, color temperature, or tint adjustment to make first. • Improved capture and recipe-saving workflows for reflected-light, gray-card, and diffuser references. • More reliable library saves and a redesigned app icon.
