I had to shoot an apartment building exterior for my work yesterday, and I used the opportunity to rent a Canon 24mm tilt/shift lens.
Interesting experience, and a frustrating experience. I admit that I didn't (and probably still don't) have a clue how to use a T/S lens. If anyoe has advice on the proper use of a T/S, I'd sure like to hear it.
The thing I didn't count on was that the 24mm would actually not be short enough to capture the image from the vantage point that the client wanted, mostly due to the "cropping factor". With the crop, the lens was effectively a 40mm, which isn't particularly short.
The goal of the gig was to reproduce an image that they only own in B&W, but in color. I tinkered with the T/S for about 20 minutes (an eternity when there's a hyperactive advertising executive alternately hovering over my head making suggestions, and wandering into the frame) before I realized I couldn't achieve what the clien wanted. I wound up shooting it with my trusty (and contrasty) Sigma 12-24 zoom.
This seems to me a sort of stupid question, but here it goes: does anyone make an adaptor that makes a DSLR lens shorter? I've seen teleconverters in a variety of powers of magnification, but nothing that goes the other way.

I don't think there's anything to make lenses wider angle, although I have heard it mentioned before.
Perhaps it's worth investing in a cheap film body?

| I believe that Photoshop CS-2 has a new perspective-correction feature, doesn't it? Since you went ahead and shot with your Sigma 12-24, you might now try using that feature on the best of those shots and get the result your client wanted after all. (Good excuse to upgrade, anyway!) |

OK, here it goes:
The Tilt/Shift image:

The 12-24 zoom image:

As you can see, the T/S doesn't have nearly enough coverage, and it was impractical to back away further.
RE: film body... yes, I've been considering it. I have my first commercial wedding job this fall, and I think it may be worth the investment.
RE: CS2 perspective correction tool... I can't remember when the
Free Transform" function was initiated, but I think I recall it as far back as Photoshop 5. When you hold down the Command/Control (Mac/PC) key and drag the Bezier handles, you can achieve pretty much any perspective distortion you want. I wanted, I did, and they look pretty reasonable:

You "abuse" the pixels at the top less if you drag the top handles wider and the bottom handles narrower, rather than doing the perspective correction entirely with the top handles.
RE: Luminous Landscape article: yes, I'd read that prior to the shoot -- the line about "just tilt it an fiddle with the focus" sort of gave me a false sense of confidence. ;)

Since you're correcting the perspective distortion in camera and creating a fairly flat image shouldn't it be no problem to stitch two or more images together to achieve the desired frame?
EDIT: BTW... If non-members wish to see the above linked images you need to change "portfolio_edit" to "image" like...

//www.dpchallenge.com/image.php?IMAGE_ID=191469
//www.dpchallenge.com/image.php?IMAGE_ID=191472
