Using this UV light measuring tool today for the first time.. It is helping me with exposure. Will keep experimenting with the meter.
The way I used it was to just meter the sunlight that is on the scene. It gave me a sense of what I had. It helped. I did not feel as blind. The Uv number varied from 5.0 to 0.0 during the day. Most times around 2.3-3.5.
If the number changed between plates, I would adjust exposure. Still figuring that out.
