Re: Looking at it from the numberer of pixels, I don't see a difference

The simplified formula for depth of field is:

Depth = f# x k x (distance / focal length)^2

Where k is a small number depending on the units of "Depth" and the acceptable blur diameter.

The basis for my suggestion is that Depth increases with distance squared.  So when you double distance, the Depth increases by a factor of four.

Dofmaster.com will solve the formula for you but the results will depart slightly from the formula due to their using a more complicated formula.
