I'm ideally looking for an example of the depth of field I can create with tilt on technical plate cameras. Wide and/or Long lens. Is the effect minimal given the usual 5.6min aperture on so many of the Digitar lenses? Am I forced to shoot 4x5 when I need shallow depth of field? I know a lot of the forum shoots at optimal f11 most of the time, but I have been extremely happy with the results from my 47mm Digitar at 5.6 on my Cambo WRS1000 body.
Best,
Justin

Justin,
Tilt (or swing) is done by changing the sharpness plane from being parallel to the lens and film planes in 0-position (lens and film planes parallel) and get it in a position where the extension of the depth of field becomes smaller, thus allowing for less stopping-down for the same depth of field (sharpness).
The effect can be huge, saving sometimes 3, 4, 5, ... f-stops. Sometimes, when the subject extends the same in all 3 dimensions of space, it brings nothing. in Some situations you can get all sharp, from front to infinity at f 5.6
So it always depends on the subject.

There are some basic samples here: http://www.cambridgeincolour.com/tutorials/tilt-shift-lenses2.htm

Gentlemen I think Justin is actually asking for the opposite effect.
Justin, tilt can be used to increase apparent depth-of-field or to reduce apparent depth of field.
Are you trying to get the miniturization (http://visualphotoguide.com/tilt-shift-photoshop-tutorial-how-to-make-fake-miniature-scenes/) look, eyes-only-in-focus look (tilted portraits) or a front-to-back ultra-(apparent)-depth-of-field image?
If you clarify the answers here will be more pertinent.

Thanks for the responses guys.
I'm not looking for the foreground to infinity focus as it is shown in this article. http://www.cambo.com/WRS_40TS.html
I'm looking to achieve the only eyes in focus photos I guess (even though I am not shooting eyes). I'm wondering if the tilts available in the cambo wide lenses are extreme enough to create those tilt effects.
I will try to post an example of the depth of field I am trying to achieve when I am back at my work computer.
