The update to include incident meter reading is awesome.

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!

(Thanks for listening to feedback to include the incident meter capabilities 😉 )
