I?m looking for some advice on a focusing situation that I continue to wrestle w ith. I mostly photograph in the mountains where there is often an implied need for forward tilt to bring the close foreground and mountain background to the cl osest difference in focus (thinking of the tutorial on the LF homepage). The te nant and problem being that, as the lens is tilted the focal plane becomes paral lel to a horizontal landscape. As you draw a horizontal line between closest an d farthest objects, only the objects or parts of objects that touch the plane wi ll be in focus. Everything above or below that plane will not be in perfect foc us.
My dilemma being how to be more precise with getting these objects below the pla ne in focus while still using the close/far difference in focus to determine opt imum f-stop. It appears that Fielder (very generally stated) brings close and f ar objects into focus using tilt and then compensates for the mid-ground using f -stop. Doing it this way requires me to go back to my millimeter ruler on my fo cus rail and focus again on the mid-ground objects in order to determine my opti mum f- stop (by using the technique where f-stop is determined by the differenc e in focus between the two extremes of close and far). Others have suggested th at you use a focus point for far focus as something, say, only a third of the wa y up the mountain when adjusting tilt. Again, this seems to require a refocus o n the top of the mountain to determine optimum f-stop?
Assuming I?ve bumbled through this enough to make sense, am I approaching this p roblem correctly, and can you offer suggestions to help me get better at this? Thanks for the help.
