## This App is a Light Meter Description
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.

## This App is a Light Meter Reviews in United States

### ***** "Just what I need"
Great little app for calculating long pinhole photo exposures
-- dobsrah, 2025-01-10

### ****- "Elegant, Simple App I Wish Was Slightly Expanded"
I love how simple this app is, and it's helpful under bright to cloudy daylight for shooting with a pinhole camera. The app won't calculate longer exposures, however, insisting that certain scenarios (incandescent, lighting, for instance) are "too dark". I've used a paper dial to calculate appropriate exposure times for those scenarios, but would really love to see this app be able to handle that. That being said, I really appreciate the simplicity and clean interface. It's perfect for students or beginners, and the inverter feature is a great teaching tool. Thank you so much for developing this! 🙏🏼
-- ScoutShoots, 2024-06-05

### ****- "Good app with some flaw’s"
I think this app needs adjustable f/stops and adjustable iso
-- Tuyo1234, 2022-11-30

### ***** "Perfect complement to This Book is a Camera"
Leveled up the user experience of pinhole photography 1000%
-- greensilence, 2021-03-31

### ***-- "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.
-- visualsofjc, 2021-01-21

### ***** "Works really well, easy to understand!"
This is a really well-made app, and is very self-explanatory. I went to the class to make one of these cameras, and it works!
-- LittleHappyBro, 2019-02-13

### ***** "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.
