Hi everyone,
To the best of my understand of DOF, it is affected by the focal length of lens, aperture size and lens/subject distance. My question is, how do i know how much is the DOF thru calculation if i hv the 3 above mentioned factors known?
I know that on my D100, there's a DOF preview button but find it hard to judge esp in low light condition.
Hope someone can enlighten me
