DOF Master.     http://www.dofmaster.com/custom.html             A free program to produce a Depth Of Field calculator for use in the field. This program allows you to customise the tool to your specific equipment.  

Depth of field scales are elegant tools for quickly and easily calculating depth of field and hyperfocal distance. Unfortunately, lens manufacturers don't engrave scales on lenses anymore. Now you can use DOFMaster to make your own scales.

Use DOFMaster to make depth of field scales for use in the field. Just set the focus distance, and read the near and far focus distances. Easily calculate the hyperfocal distance for your lens at any aperture.

Customize the scale for your needs:

  • Use feet or meters on the distance scale

  • Stretch or shrink the distance scale as necessary for focal lengths from 3 mm to 1200 mm

  • Print a scale for any format, digital to 8x10

  • Put as many as 4 focal lengths on a scale

  • Select apertures as small as f/64

  • Choose any circle of confusion

    This is a very good solution to the problem of controlling the zone of sharpest focus in photos.
