[LargeFormat] Using Hyperfocal techniques - a survey

[Clive Warren]

Dear All,

Do you have favorite techniques for focusing in the field using 
hyperfocal focusing? Some people print out scales for use on the 
camera bed, some cameras have built-in scales on the focusing knobs 
(eg Sinar) and some people use a near far focusing method using the 
ground glass and know where they are with the  depth of field of 
their particular focal length lens and apertures.

Do you keep the information in your head or use printed tables? Do 
you use tools such as the depth of field calculator at 
http://www.cocam.co.uk/CoCamWS/Services/DOF.htm

Do you have a preference for circles of confusion constants?

Cheers,
        Clive
