LightCue is a light meter for film photographers — whether you're shooting your first roll or you've lost count. Point your phone at the scene, set the exposure you want, and trust the reading when you trip the shutter on your real camera. New to some of this? Little tips pop up along the way to explain reciprocity, ND filters, flash, and depth of field as you go. The free version is a complete light meter on its own — matrix, center, and spot metering ready to read any scene from your very first roll. What you get for free: • Matrix, center, and spot metering, with a confidence read so you know when to trust it and when to bracket. • Lock your shutter or aperture and let the meter solve the other, plus EV compensation and ISO customization. • Composition guidelines and viewfinder size selection. • Friendly built-in tutorials and hints. If you fall down the rabbit hole: LightCue Pro is an optional subscription (or a one-time Lifetime purchase) for folks who want the deep stuff — the full film stock library, per-emulsion reciprocity correction, an ND filter calculator, manual flash (Guide Number) metering, LiDAR-backed distance measurement for zone and depth-of-field metering, and an exposure log. Totally optional, and the free meter keeps working exactly the same either way.
