About this app

Photo Friend is a no-frills exposure calculator app, for photographers and movie makers that know their way. The app can also work as light meter by using the phone camera or the light sensor. The calculator can estimate depth-of-field, too.

Visit our Facebook page: https://www.facebook.com/photofriendapp/

Highlight features:

* Easy and intuitive exposure calculator. No typing, no configurations! Just drag each gauge to the desired value. The other meters move to make good exposure.

* Reflected light meter. If your phone has a camera and you grant access, a viewfinder is shown on the main screen. Point to the subject and touch the viewfinder to take a picture. The EV will be estimated based on the picture.

* Incident light meter. If your phone has a light sensor, the illuminance in lux is shown, and the estimated EV. Touch the viewfinder area to transport EV to the respective calculator gauge.

* Easy-to-use depth-of-field calculator. Just dial aperture, focal length and subject distance. DoF is expressed as numbers and graphically. Distance unit and DoF parameters can be tweaked at Settings.

Photo Friend is a free app with in-app purchase of ad-free mode.

Ads are too aggressive. Bought it though. Essential additions would be an measure button that locks the measurement, even better would be an aggregate measurement mode to take multiple measures and average. Also, it would be useful to be able to preload lens profiles with focal length, min/max aperture, film size. Shooting on Mamiya 645, RB67, and 35mm. Also need to be to lock ISO setting. Typical workflow: Set ISO. Set lens. Measure. If backlight, measure again. Calculate. Shoot. Repeat.

I bought this to help me with an vintage Zeiss 6X9 camera. The application is great. I would suggest that being able to lock ISO and Focal Length would be much help to those using film cameras and / or prime lenses. That would be a 5+ Star application, especially given the very reasonable price. I also have an observation, when I set my 6X9 format and check 35mm equivalent the focal length and equivalent display the same value.

App is fantastic, straightforward and easy way to use my phone as a light meter and calculate shutter speed and aperture for my film camera. The sliders are extremely intuitive and quick, exactly the app I was looking for after trying a couple other popular ones and being disappointed.
