Matej, you wrote;

In this case, I had pointed the camera down about 15 degrees, and after defishing the verticals were diverging crazily, so it was the correction of the leaning verticals (which produced hugely deformed feet) that caused me to cut off the bottom area. My preference for panorama format helped...
>I'm also curious whether there is an analogue way of de-fishing. Correcting converging lines is very much possible, but curves.... ?
Yes, I used to do this myself--tilting the paper is fine for leaning verticals, but you'd need to be able to "dome" the paper to correct the curves. Victory for the digital darkroom, I'm afraid.

I like the unusual perspective, roger. Gives this scene a lot of interest, where you want to study it just that bit longer.
Must get one of these fisheye lens for my T70.

Here is the uncorrected orignal fisheye image. I think it was worthwhile defishing this one.
