User reviews

I use it every time

This app is great for metering, getting a view of the picture the pinhole makes, and incorporating reciprocity curves. Even works with slide film (which is known for being tough to meter). I recommend it to everyone.

The only potential feedback I could give would be to match the zoom and shape) square vs rectangle) to the image size and focal length, and maybe to allow a “blurry” view to better anticipate what the pinhole camera might capture.

Great But Room for Improvement

This is really the best pinhole light metering app out there, and I can’t knock it. I make my own pinhole cameras, and I need the option to manually enter my own f stop if it does not appear on pulldown list. Otherwise very well done!

Essential for pinhole photographers

I’ve been using the app for more than 3 years. My absolute recommendation for all enthusiasts of pinhole photography. A must have

Very nice app!

Very helpful app for pinhole photos. The metering works well and it is easy to find and use aperture and film data. Timer helps a lot also.

Good support, though I needed extra steps because developer uses Facebook for support. [I don’t like being tracked by Facebook and refuse to install or use it.] Developer responded quickly after I used my review to request support.

Need support without facebook

I do not and will never have a facebook account, but I do need support.
The app crashes within 5-10 seconds after I open it. After several tries, I deleted and re-installed the app but still getting same crashes. Can’t use app at all now.
