Re: No need for a tilt shift lens.
As you point out, the effects of shift can be accomplished through
resampling in a Pantools-type application.
Tilt, however, is a completely different matter. Here's what you can do with
tilt:

I took that on an MPP VII 4x5 view camera using a Schneider 150mm Symmar
using both front and rear-tilt. Note that the focus plane actually runs
*horizontally*, parallel to the axis of the lens.
Another way of taking it would be to have the focal plane vertical, but at
an incline, so it ran through both bottles, using horizontal-tilt instead of
vertical tilt.
If you took a picture with a very large depth of field, you might be able to
selectively blur bits of it to try and get the same effect, but it;s going
to be hard work, and for close-ups you may not be able to get the DoF in the
first place. I doubt I would have been able to get both bottles in focus if
I'd taken it on my 5D, even if the lens let me stop down all the way to
f/32.
Image details - 150mm, f/22, 1/400, 400 ISO Polaroid B&W. I could probably
have got the tops looking sharp as well if I'd stopped down to f/64, but I
specifically wanted something that demonstrated tilt.
