I am trying to improve my landscape photo skills. Most of my pictures are OK but either the foreground or background is typically not as sharp as it could be. From what I am reading on hyperfocal distance it is critical to focus the camera on that point for maximum sharpness (1/2 of HD to infinity).
Can some help me understand how to best estimate subject distance while shooting? As an example, how does one exactly focus say at a point that is 4.5 meters ahead? Do you folks just approximate or use some other tool?
I cannot find subject distance being returned on the camera displays (D90 or old D70).
