About SlowLightMeter
As a film photographer, I wanted an accurate yet simple reflective and incident light meter. After trying several, I decided to build my own. This light meter continuously measures light, so it requires minimal interaction during a shoot. To avoid accidentally changing film ISO, I added an ISO lock. And since I shoot often with my Hasselblad, I made EV values a core feature of the app.
