I mostly tilt, I sometimes shift but I never used both together. Should I? This link suggests that it can increase DoF. This is interesting but how does it work in practice? What is your personal experience? Please post pictures, add description and technical data.
Here's a good example. This is max shift down with about 6-7 degree tilt down as well, at like f/6.3...sharp from 1 foot in front to infinity. I really liked my tilt-shift, but the times I used it were infrequent enough that I couldn't justify keeping a $1000 lens in my bag for use a few times a year. If I were a working architectural photographer rather than a hobbyist, though, I'd use a tilt-shift all the time.
And this has no shift (I hadn't modified my TS-E to have both in the same axis yet), but uses tilt for increased DOF. The foreground is like 4-6 inches in front of the lens, yet the buildings in the distance are also sharp, and again, this is at like f/5.6 or f/6.3. The tops of the reeds close are OOF because the focus wedge isn't high enough at that point, but the main line of the photo is in focus all the way. This is max tilt down.
I'm like you, I pretty much used tilt only for a long time. In fact I thought about getting a Schneider 28mm PC converted to tilt at one time. When I bought the 17mm TSE though I started seeing oportunites for shift and then found I was using both. It could be argued that I didn't need both because it's so wide, but it's made me think of other shots now.
Tilt to get the front and back in focus and shift to make the boat "loom" over the viewer a little more (I screwed up the the mapping on this one so it looks a little over processed). http://i.pbase.com/g3/63/551663/2/122912270.OTNkeAZb.jpg
Only tilt increases DOF, assuming a camera that's level in both L–R and front–back planes. Shift selects the section of the available image circle. I can expand if you wish. cheers, KL
Exactly. The tilt is the only thing that gives the big DOF...the shift on my first shot just prevents the buildings at the top of the frame from splaying outward (diverging verticals in this case).

TIA.

Yakim,
I think you're missing the reason for this. Shift or rise and fall will allow you to alter the composition while keeping the verticals, vertical. Tilt uses alters the plane of focus to allow near-far in focus with a larger aperture. I've used rise or fall with tilt and even swing on occasion in my view camera. My particular field camera doesn't have shift, but it can be done with swings front and rear.
Notice in Jman's example the top buildings are vertical, but the buildings in the bottom image are leaning out. In the first, the camera back is parallel to the buildings and the shift is moving the composition. In the second, the camera back is leaning into the composition and the buildings lean out.

Indeed I wondered what shift has to do with DoF. Thanks for clarifying this.

I don't have a TS lens. I have a TS adapter (Mirex, Mamiya M645 to EF). When I tilt the lens down/up, the shift is right/left. What does that mean about the axis?
A little more: most people overdo tilt degree angles, which can lead to loss of DOF, the exact opposite of the traditional aim. I made up a set of tables for each of my Mamiya 645 lenses for my regular tripod heights.
So far, I see little need for rise and fall - just as well, since the Mirex has the two movements at 90 degrees to each other. I have not yet had time to test this, but this restriction will not impede down tilt plus horizontal shift - this should deliver solid panoramas with excellent DOF, provided I watch the near foreground for parallax problems, since the shift does not use the nodal point.
The guy at Outback whatever with the German name has written a way around this for shifters, incorporating a small slide of the camera in the horizontal plane, along his plate...but the example shown had a lot of the subject very close up, perhaps to show you need to make this adjustment for such shots. For big sweeping shots, I have seen plenty where this does not arise as a problem...

It means the axes of tilt and shift are 90 degrees opposed with your adapter.
Practically, it means if you wish to correct for converging verticals in an image using shift, you will not be able to apply tilt to maximize fore-to-background DOF vertically (in the same plane/direction as your shift movement).

I usually don't use much tilt with my TS-E 17 and use a lot more shift. At f9-11 which I often shoot it at with the 17, the DOF is usually large enough and tilt doesn't add that much to it.
With a TS-E 90 I imagine I would use tilt a lot more often and with larger tilt angles.

Here's a handheld example of shift up to keep the verticals and a full swing to limit depth. 24mm T/SII f/3.5. You use whatever it takes to make the image you want.

This effect does make the building look like a minature model.
