Exposure Light Meter is a free Android app developed by SerializedName, designed to help photographers set exposure settings on their cameras. This app is especially useful for those who shoot on film, as it provides a good helper to determine the correct exposure settings.

To use the app, users need to set the ISO and point the phone at the subject. Then, when setting the shutter-aperture pair on the camera, they should focus on the ruler at the bottom of the screen. The ruler displays the number of aperture in the first row and the shutter speed corresponding to the current exposure in the second row. The ruler can be moved horizontally, making it easy to adjust the settings.

Exposure Light Meter also has an exposure meter mode, which displays the exposure value (EV) at the top of the screen. This feature is particularly helpful for photographers who want to achieve a certain level of brightness or contrast in their images.

Overall, Exposure Light Meter is a useful app for film photographers who want to ensure they get the right exposure settings for their shots. It is easy to use and provides accurate information, making it a valuable tool for any photographer's toolkit.
