I am longing for techniques to use with a tilt/shift lens to maximize my depth of field in landscape shots.
Thanks

If you would like to post, you'll need to register. Note that if you have a BCG store account, you'll need a new, separate account here (we keep the two sites separate for security purposes).
Great link above, but this is pretty good for how to apply tilt to align plane of focus with your intended subjects: https://www.cambridgeincolour.com/tutorials/tilt-shift-lenses2.htmI am longing for techniques to use with a tilt/shift lens to maximize my depth of field in landscape shots.

Well, the DOF does change but not in the usual sense. Instead of being a rectangular box as it were, it becomes a wedge, slightly narrower at the camera and widens as you get farther away. This would be relative to the lens and it's tilt, as soon as it goes off paralell from the film plane, the DOF is no longer equal across the image circle. The usual method is to determine what you want the plane of focus to be, noting that it must intersect the film plane somewhere. Then the lens tilt is set to intersect that point. Only when all three planes intersect is the S-principle in effect. Once you've done it in the field it's actually quite easy......easier than spelling or pronouncing the name!Great link above, but this is pretty good for how to apply tilt to align plane of focus with your intended subjects: https://www.cambridgeincolour.com/tutorials/tilt-shift-lenses2.htm
FWIW, Shift is great for dealing with perspective issues like converging lines that would result for angling your camera up to catch tall trees or architectural shots but Tilt is what you're after to maximize apparent DOF. Note the actual DOF doesn't really change, you've just aligned the plane of best focus and the associated DOF better to the elements in your image.
Yes, that's a more accurate description. But tilting for the purpose of aligning the plane of best focus is very different than simply stopping down for increased DOF as it allows some really interesting creative effects like establishing a slanting plane of best focus but shooting with a wide aperture to have dramatic focus fall off as you move away from that slanted plane.Well, the DOF does change but not in the usual sense.
