Store screenshots supplied by the developer.
Lghtmtr is a beautifully simple light meter that helps you find — and understand — the ideal exposure settings for a scene.
Built for film photographers and anyone learning the craft, it makes the relationship between ISO, aperture, and shutter speed feel intuitive and the visual feedback helps reinforce the connection between them.
Take a reading, get your settings, and start exploring. Adjust one value and the others respond instantly. Lock settings to experiment and see how each change affects your exposure.
You can easily add camera profiles to the app to limit the possible values to what's most relevant to your camera and lens combination.
With a visual reference of the scene behind every reading, Lghtmtr helps you shoot with clarity and confidence.

lghtmtrWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
