## What is 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.

## Key features

- Reflective and incident light metering
- Continuous light measurement
- ISO lock
- EV value display
- Simple interface

This is the perfect simple light meter - includes both reflective and incident reading. No fuss, just meter the scene. Press button to lock reading, or let it refresh automatically. 

Awesome!
