IMPORTANT NOTE: You need an 18% grey card to use this app
PocketChris Incident Meter calculates the exposure time from two light measurements taken off a grey card. It works like an incident light meter for your camera. Use a simple 18% grey card, take two spot measurements with your camera and get exposures that rival an expensive incident light meter.
Here's how:
- set your camera to manual mode, choose an appropriate ISO and aperture
- take two spot measurements off the 18% grey card, one with the card facing the brighter side, one with the card facing the darker side
- enter both shutter speed values into the app and set your camera to the closest shutter speed suggested by the app
Now take the picture with perfect exposure.
The reflective light meter in your camera evaluates the brightness of the objects in the scene and thus will often lead to over- or underexposure. As a result photographs of snow scenes end up grey and pictures of black objects tend to be too bright.
An incident light meter sees the actual light and is a lot more precise. Unfortunately an incident light meter can also easily cost hundreds of dollars or more.

This is not a light meter
v700
Unlike other light meter apps, this app does not take any light measurements. It should be called a calculator not a reader. You have to metering in your camera. Then you enter two numbers into the app (the two shutter speeds) and it calculates a weighted average of your two numbers. That's all the app does. It's not much bang for the buck! The instructions on metering provided by the app aren't anything you couldn't find easily and better for free on the web. The app is just a plug for the author's photography training.
Really?
Mad as hell 2013
Buyer beware this is sad Attempt to exploit you and your $.99. This is a calculator and not a meter. Be honest Just say that.
Not a meter

As said in previous reviews, this is a light calculator that requires you to use a grey card. I can figure out my exposures on a digital camera based on my histogram. What I really wanted was a meter to get estimates on exposure for my film camera.
