About this app

LightMeter is a practical light meter for photographers who shoot film and want to keep one in their pocket.

It includes two metering modes:

• Reflected-light metering using the camera
• Incident-light metering using the light sensor

⚠️ Performance and accuracy depend on each device’s hardware. Reflected-light metering has more limited compatibility, while incident-light metering works on most devices.

Features:

• ISO range from 3 to 6400
• Low-light warning
• Optional EXIF and sensor information
• Calibration adjustment
• Vibration when measuring and holding a reading
• Reading hold for incident-light metering
• Alternative ISO selector
• Saves the current state and selected ISO
• Spot metering, if supported by the camera

I shot an entire vacation using this app. 8 rolls of film with essentially very basic entry level knowledge of film photography. In terms of exposure, almost all photos turned out looking great. I tried using other apps and they just weren't as intuitive as this one. I like how simple this app is and for someone who has probably bought less than 10 apps ever, this is one that I am happy I paid for.

Excellent! Nice to have meter with an intuitive, analog readout. I love the simple calculator dial of my Weston 737, and this works just as well. Unfortunately the settings tab is placed where I can't get to it: if I try to touch it, phone settings come down instead of app settings. I would LOVE to see continuous reading in reflected mode. Perhaps this is a little ambitious, but that would make this my favorite metering app by a huge margin.

compared to my Gossen Luna pro F, I calibrated it in reflected and incident. it seemed l to be reasonably accurate. if it had both high and low , or high calibration points, plus temp reading it would be awesome. but that's a lot to ask. I would not quibble over the difference in between any two meters I use as there are always small differences. going to try it on ground glass of my large format, and on easel under enlarger.
