Photo Friend is a straightforward exposure calculator designed for photographers and filmmakers who are familiar with their craft. The app doubles as a light meter, utilizing either your phone's camera or its light sensor. Additionally, it offers functionality to estimate depth-of-field (DoF).
User-Friendly Exposure Calculator
Enjoy an intuitive interface with no typing or complicated configurations required. Simply drag each gauge to set your desired values, while the other meters adjust automatically to ensure optimal exposure.
Reflected Light Meter
If your device has a camera and you provide access, you'll see a viewfinder on the main screen. Point at your subject and tap the viewfinder to capture an image. The app will estimate the exposure value (EV) based on that picture.
Incident Light Meter
If your phone is equipped with a light sensor, it will display the illuminance in lux along with the estimated EV. Simply touch the viewfinder area to transfer the EV into the corresponding calculator gauge.
Depth-of-Field Calculator
Input the aperture, focal length, and subject distance to easily calculate DoF, which is presented both numerically and graphically. You can also customize the unit of measurement and DoF parameters in the Settings menu.
Photo Friend is available as a free app, with an optional in-app purchase for an ad-free experience.
Recently added film sizes: 4x5 in and 8x10 in.
