Originally posted by MattGunn With SLRs and DSLRs, tilt usually appears to be used to put much of the image out of focus (for minature effects ets) but with large format it is used to put most of the image in focus and control distortion.
Actually, my sole reason for getting into tilt photography is to put as much of image in focus at wider apertures as I can, for landscapes. I actually see the "selective focus effect" of an extreme tilt as more of a "glorified lensbaby effect" which is nice, but not what I got the lens and adapters for. Heck, I got Stroebel's "View Camera Techniques" for Christmas and have actually read some of it!
Not an expert by any means, but these
hand-held practice shots illustrate my efforts (I was "focusing" on the sign in the foreground, at the bottom of the frame):
No tilt (50mm Flektogon @ f/5.6):
~5 deg. tilt down (50mm Flektogon @ f/5.6):
**Note how the deck boards are not in focus in the second shot until quite a ways out, but the tops of the railings are? It's a "wedge-shaped focus area" alright!
