Description

Plain DoF app would give the depth of field details and hyperfocal distance based on aperture, crop factor/sensor size, f stop and distance to the subject.

Depth of field is the most important concept in photography. It determines the sharpness of a photograph and tells you how much of a photograph is in focus. Depth of field can be used to soften objects within the frame or to make a whole photograph look sharp. Depth of field primarily depends on three main factors: the aperture, the focal length and the distance to focused subject.

For an appropriate depth of field for your photograph, you can use the following guidelines.

To minimize the depth of field, any one of the following can be used or can be combined as you prefer for your photograph.

1. Use smaller aperture (and/or)

2. Use longer focal length (and/or)

3. Move closer to the subject

To maximize the depth of field, any one of the following can be used or can be combined as you prefer for your photograph.

1. Use larger aperture (and/or)

2. Use smaller focal length (and/or)

3. Move away from the subject

Hyperfocal distance is the shortest distance at which a lens can be focused so that depth of field stretches to infinity for a given aperture and focal length. It is purely depended on just aperture and focal length. So when focused at hyperfocal distance, the depth of field is from exactly half the hyperfocal distance to infinity.

5/5 stars

Works Fine with no frills.

:
Need a DoF calculator? Do you already know your camera's crop factor multiplier?

Then this app does the job well and does it for free in both metric and imperial, which a lot of the more promising paid apps don't.

4/5 stars

Great "Plain" App

:
This app is great.
Does exactly what it says it does, specially without an over cluttered GUI.

The reason for only 4 stars is that it is a little annoying changing your distance. Change that feature to be a scroll wheel or something better instead of typing each value, and you got yourself 5 stars!
