"Fixing" distortion?

A cut & paste would've had the wrong perspective. The sign removal and some
of the pavement & wall was done with gradient masked vanishing point cloning
in PS. The colour was corrected for the ambient temperature and enhanced

If I could afford a Canon 24mm TS lens I would get one because it would
let me compose 'perfectly' at capture

A little cut and paste over the poster as well.

Color corrected or enhanced?

I recently bought a 15mm full-frame fisheye, mainly for fun and
amusement, but it could be used for some serious wide-angles, also. I
have had thoughts about buying Canon's 24mm tilt-shift lens... someday.
I remember Bret rented one and decided it wasn't worth buying one.

I have been doing some reading and thinking and have started to wonder
if maybe using my 15mm, or any lens, and a program such as Image Align
might be a cheaper and reasonable alternative than the $1100+/- that
the tilt-shift lens would cost. Any thoughts or experiences?

I haven't tried it, but I'sd suspect that once you correct the
distortion and then crop the resulting pincushion-shaped image to a
rectangle, you'd get effectively the same picture as a 21 or perhaps
even 24mm corrected lens.

It isn't actually necessary to use a shift lens; all they do is crop the
image circle differently by moving the image centre away from the frame
centre. You can get the same effect by using a high enough resolution
sensor or film and then cropping out the unwanted forground in
photoshop/on the enlarger. Sure you lose some resolution but if you have
plenty to start with, then you might be able to afford it.
