Then it says the hyperfocal distance is 1.87 ft and depth of field extends 0.935 ft to infinity. So do I keep my camera focussed on my subject at 10 ft? Does this mean that whatever the subject distance is, the hyperfocal distance remains constant when using the same aperture, i.e. HF distance1.87 ft at f16 at 13mm focal length with Canon EOS 60D? I have read that best results are gained "when focus is set at the hyperfocal distance". Is that what I am doing above? I don't want to get involved in the mathematics of it ( CoC and all that) but need some help.
Depth of Field (DOF) for the values u have said here, i.e. Aperture f/16, Focal length 13mm for your camera (Canon 60D) comes to 2 feet. That means if you set the above values and focus at 2 feet, everything from 1 feet to infinity should be acceptably sharp.

For knowing how i arrived at this magic figure of 2 feet, you could check here http://photographypoints.blogspot.in...implified.html
