About Photo Friend exposure and DoF

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.

Layout adapted for iPhone X, updated libraries
Oct 2, 2017
Added 'lock' for ISO, aperture and shutter. Tap three times in rapid succession to lock/unlock a gauge.

Locks are useful for e.g. analog film photography. A roll of film does not change ISO, so it makes sense to lock the ISO during the shooting session.
