### 5/5 — Many Thanks

*2024-10-20*

This app is exactly what I need in order to learn how to apply Ansel Adams Zone System to my own photography. The concurrent display of many parts of the image is a great timesaver when compared to taking many spot readings and trying to remember each one.  There is one additional feature that would be nice, and that is an additional single spot meter such as 2 degrees.
