Take the guesswork out of calculating your pinhole camera’s exposure time by using your phone or tablet as a light meter.

The meter is designed to work with any pinhole camera, and its particularly well suited for Kelli Anderson’s ‘This Book is a Camera.’

Includes a timer to count down every second to your ideal exposure, and an inverter to reveal the final image of your pinhole negative.

What’s New

Version 1.0.4

Adjustable aperture (f-stop) and ISO film values enable you to use This App is a Light Meter with any pinhole camera setup! Just tap on the 'Aperture' or 'ISO' buttons to select your camera's settings.

Just what I needed!

I love my Camera Book but light metering has until now been a pain point. None of the other light meter apps available were made with pinhole photography in mind. They are also mostly ugly, harder to use AND cost money.

Enter This App is a Light Meter! It solves ALL of the aforementioned problems. Not only does it work perfectly, it is super easy to use, and even has a most helpful bonus feature: An inverter. Now in one FREE app I can get the right exposure time instantly without having to fiddle with settings, set a timer, and even invert my negative after development. So great! Thanks for making this.

Great, but...

This is the best app for calculating exposure times for a pinhole camera. However, it needs a feature where we can change our ISO and f-stop. A lot of people use Ilford RC paper which is around ISO 5. Sometimes our pinholes will be bigger or smaller as well as our focal length. Being able to change these variables would be fantastic.
