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

Greetings Clive,

When using LF I simply compose and focus on the GG.  When I need extended 
DOF, I focus 1/3 - 1/2 way in, tilt, then stop down until it all comes in.  
For me trying to work with scales, range finders, etc. is just 
counter-intuitive and not my way of doing things, but that's just me.

MF is a different matter.  I don't have the luxury of tilt, so I carefully 
check the near and far distances and split the difference.

Regards, Pete
