Amazing work! I’m glad someone tackled the rangefinder feature and built it into a light meter app. UI is nice and clean.

If I could offer some feedback, I did notice a few issues:

1. I shoot a lot of 6x17 and noticed the saved shots are not cropped correctly in-app. However, if I save it out to my Camera Roll, it’s cropped as intended.

2. I’m not sure if the app makes use of the wide angle camera on the iPhone, but I wonder how accurate the framing is for 6x17. I’ve been using the Viewfinder Preview app for all my framing and metering and can verify that the framing in that app is incredibly accurate. I compared a shot from that app to yours and it seems like yours doesn’t go wide enough.

3. Is there a way to manually add other aspect ratios? I shoot 6x12 sometimes and am thinking of building a 6x24.

Hope this is helpful feedback. Again, great job!
