Description
Photo Friend is an intuitive exposure calculator app for photographers and movie makers that know their way around a camera. The app can also work as light meter by using the phone camera. The calculator can estimate depth-of-field as well.
Highlight features:
* Easy and intuitive exposure calculator. Just drag each gauge (absolute exposure value, ISO, shutter speed, aperture) to the desired value. The other gauges move to make good exposure. For example, if you change EV, ISO and aperture, the shutter speed adjusts accordingly. (The EV meter only moves by itself when you use the light meter feature.)
* Light meter. Grant access to camera when the app asks, and 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 with basis on the picture. Histogram and spot metering are available as well.
* Easy-to-use depth-of-field calculator. Just dial aperture, focal length and subject distance. DoF is expressed as numbers and graphically. You can fine-tune the DoF calculation parameters in Settings.

Ratings and Reviews
Awesome
The best aid for working out manual exposure values, either from a starting point from a light meter or rule of thumb, or by using the camera feature. This app might be described as ‘basic’, but it’s exactly the way I want it. Nothing more needed, does it’s job and you can get on with photography or whatever. Highly recommended, deserves more ratings. Looks nice enough too, although I might opt for a white untextured background on the dials and white borders, would maybe be a touch less skeuomorphic and more clean looking in my view. Thanks to the developer for making this free. Would be nice to pay a €1 or something to get rid of ads though!
Developer Response ,
The app offers to buy the ad-free option once a day or so.
By far the best light meter app for my workflow
If only the EV compensation / filter factor slider would affect the exposure of the viewfinder image. At present I have to open the camera app, tweak the exposure, take an image, then note the EV adjustment, then go back to (the otherwise completely awesome) Photo friend and dial in the adjustment. What do you reckon Elvis? I know you can do it. I believe in you.
Very nice app
Simple but very effective!
Developer quick to respond to feedback and added large format film sizes (4x5 and 8x10 inch) at my request.
Thanks!
