I have been doing some reading in my free time and recently I saw this magazine article about hyperfocal distances. It was really useful as I will be going on a USA trip soon and expect to take a lot of landscape photos especially with my people inside them so maximum depth of field is critical.
At 17mm with a crop sensor and f11 aperture, the hyperfocal distance seems to be 4.5 ft = 1.37m, which seems strangely near. So lets say I'm taking a photo of the grand canyons, do I tilt my camera to focus on the ground 1.37m in front of me and then tilt the camera back up to take the shot? I can't seem to grasp this technique.
As a shortcut there was mention of a shortcut by focusing 1/3 into the scene. Again, I can't seem to grasp what this really means especially if you consider a strong foreground like when you go very low on the ground for a photo. 1/3 of distance the distance from where you are to the far away mountains or trees is not the same as the distance to a point at 1/3 of the photo composition if you know what I mean. So do they really mean 1/3 of the distance from me to the faraway mountains or trees? Or at a point located somewhere at 1/3 of the photo composition?
Any help in this matter would be greatly appreciated.
