My concern with the app is an age old iphone-android thing. There are say 6/7 cameras they really need to calibrate to for the iPhone app - why some iPhone models the app says you need to use a diffuser. (Piece of printer paper over the camera) Android there are 100 different implementations which I suspect detracts from accuracy.I think I tried full spectrum and blue/white to see if it made a difference, but I got basically the same numbers. I'm not sure I trust the app enough to drop all the way to 23k, but I might drop it to 30k from 42k now and see how they look. Thanks for running the calcs for me as well as the calibration suggestion!
I have a dedicated light meter arriving today or tomorrow. I’ll compare the app, my Pulse Pro and that see whats what across the types.
