This would be a great lux meter with a small change. It should display the lux level using the same sold background as when you press the “hold” button when not in “hold” mode. That is because it is very hard to read the display when taking a reading in bright sunlight or bright artificial lighting. Also I believe the “information-How to use this app” has the direct/reflected settings backward.
Always wanted this
Every day in my work and play, I am experimenting with high dynamic range images. At work I have a $5,000 light meter, but not at home. This app is an astonishingly good replacement! Thank you so much! And it's free!
I was seriously going to write my own app, but this is very good, don't need to!
Better than guessing ...
... but not by much. Shows much more light - up to ten times - then my MT-912 light meter
50,000 lux 12” under a 50W LED grow light just is a little much
