Light Meter

WBPhoto

About this app

A reflected light meter with spot metering (using the device's camera) and an incident light meter (using the device's light sensor) in one app. Tested accurate against Gossen and Sekonic meters on most devices.

Can be used for any type of camera from film SLR to pinhole to cinematographic.

In addition to the two meters, the app includes a Color Temperature (White Balance) meter, a Reciprocity Calculator, an Exposure Convert, a Manual (Sunny Sixteen) calculator, a Depth of Field calculator, and an EXIF Reader.

Ratings and reviews

I think it's a pretty good app. I've shot about 10 rolls of film using it and very rarely had exposure issues. I'm knocking off a point because the camera sensor is the most used app and in the top right corner. if you could sort apps I would give it 5 stars. I have a taller phone (S24 ultra) and have to use two hands to get to the camera sensor as is.

Didn't work. My phone is a galaxy s20 ultra and the numbers this app was giving me were way off. I pointed my phone at a very brightly lit space, set the f stop and iso accordingly, but the calculated shutter speed was ten seconds. I tried to fix it, but nothing I did made the app give me correct calculations. I don't know if it was a problem with my phone or the app itself, but unfortunately it's useless if it doesn't give me the right settings.

Fantastic. Really useful. My phone is about 0.5 of a stop off. Would be great to have a separate calibration setting, so that the plus/minus correction could just be used for working out placing the image in a particular zone etc, but hardly any inconvenience as is. A great app, love the spot meter zoomed in - super accurate. Other thoughts: if it could perform a screen grab to act as a reference, that would be cool for image review. Thank you for your work on this.
