Focal length calculator

Discussion in 'Digital Photography' started by Martin Kaltoft, Apr 11, 2004.

  1. Hi

    I've written a "Focal length calculator" script, that i'd like to share with
    you.

    It calculates what focal length you need to fille a frame of a variable size
    with an object of a variable size from a certain distance.

    For example it can tell you that you need a lense with a 175mm focal length
    to fill a 35mm frame with a 10 meter large object from 50 meters.

    The adress: http://80.62.24.182/focal.php
