About this app

Light Meter is an app that helps you calculate the right exposure settings in two ways, using your main phone camera or the front ambient light sensor. You just need to set the ISO speed of the film you're using and set the desired aperture value and the app will recalculate the shutter speed for you, simple as that.

Features:
• Calculate exposure with the main camera sensor
• Tap the aperture or shutter speed value to lock it and change priority mode
• Use the zoom menu or simple pinch to zoom function and use zoomed part as the area metering mode
• Use the Snap function to easily set desired camera parameters
• Add and save your entire shooting process to notes quickly
• Back up your notes using the backup feature
• Use the B&W mode to see how your photos will turn out in real time
• Use the Film Stock feature to choose the type of film you're shooting with

We constantly update the app to provide more features that users are looking for, so expect even more with future updates.

Thank you for using the Light Meter app.

I love the layout, it's so simple and quick to use, you can very very easily get your settings right ASAP which is so important. The ads are also not obtrusive and very unlikely to accidentally be clocked. However, the readings are pretty dang inaccurate. I've compared it against my phone's exposure settings and in anything other than perfect outdoor light this consistently gives 1-2 stop higher readings, and they tend to "stick" with anything other than dramatic changes in light.

Thank you for your feedback. We're sorry to hear that. Could you describe the method you used to test and compare the values to the email support@luminis-labs.com? The app uses the Google Camera package as your camera, so the values should be the same. Also, your camera has a fixed aperture, so the same value must be set in the app for comparison.

Excellent basic app for film cameras with either no built in meter, or a non-functional one. It works similarly to a typical aperture priority camera meter, you set film ASA, and you can choose the aperture and it will tell you the correct shutter speed, so basically an aperture priority meter. It would be nice if it could also do shutter priority though. Simple to use.

Thank you for your feedback and support Jay. Shutter priority option will be added in next feature update. EDIT: Shutter/aperture priority option and zoom option are now added with 1.4.0 update.

Light Meter presents an easy way to check light levels, which is useful for a variety of purposes. For instance, I've used it for photography, video recording, and maintaining optimal light for house plants.
