Hello Steven,

The front page of the CoCam website has a drop down menu bar about half-way
down the page with a range of photo-tools.

The CoCam Depth of Field tool allows you to select almost any film format,
focal length and f stop and then print out the resulting table.  A few
people have found the tool and given positive feedback - I use it myself to
generate tables for large format lenses.  Did this recently for a photo
trip, printed the tables and then left them behind - doh!

Hope you find the tool useful.




All the best,

             Clive   http://www.cocam.co.uk
