Usage of hyperfocal length
Posted: Thu May 14, 2009 10:18 pm
Hello, am always perplexed by usage of the hyperfocal length. Let us say, I have a chart with me based of my camera and targeted fstop and focal length and let us say it comes up as 18 ft.
Now if I am shooting a mountain from its base, then I can measure 18 ft from my tripod and manual focus to get that spot in focus (because my zoom lens does not have a DOF scale )
However, if I am shooting grandcanyon and want the little branch/shrub in front and distant mountains, how to go about it. 18 ft there, would lead me to the empty space between 2 objects...Also what happens if the 18 ft point is not part of the framed picture i.e if you want to compose beyond the point (maybe that will never be possible, but I dont know).
thanks
