This app can measure 'F number' , 'Shutter speed' or 'ISO sensitivity'.
Set these measurement values at your DSLR camera.

Digital cameras have a built-in exposure meter. However, since the built-in exposure meter is reflective, it may not be able to accurately measure exposure because it is affected by the color or gloss of the subject. In such cases, you can use this application to measure the exposure. This app uses incident light to measure exposure and is not affected by the color or gloss of the subject.
Of course, you can also use this application to take pictures with classic cameras that do not have an exposure meter.


Here's how to use this application
(1) Launch the application.
(2) Point your [Android phone], which is running the app, in front of your subject and point it towards [your camera].
(The sensor for measuring light on your Android phone is located on the front side of your phone, so point your phone towards [your camera].)
(3) Press the "MEASURE" button of the application to start measurement.
(4) Press "MEASURE" button again to finish the measurement.
(At this point, the measurement value is recorded and you can move away from the subject.)
(5) Set the shooting conditions on the application. For example, if you want to calculate the f-stop, set ISO and SS on the app. The calculated f-value will be displayed on the app.
(6) Turn on [your camera] to manual mode.
(7) Set the ISO/F/SS values displayed on the application to [your camera].
(8) Shoot with [your camera].

[Android phone] that have this application installed
