Alfred, the other one is more creative and this one has more distortion. Regards.

In architecture photography with special professional cameras, they prevent perspective distortions by shifting the lens/film planes up/down, while keeping the film plane parallel to the object plane. Unfortunately we cannot do it with our cameras, so we must do it in Photoshop (in the darkroom days I used to tilt the easel).

I correct only vertical convergence (using the crop tool), this has the effect as if I shot from a high view point - opposite the object's center - while in fact I was at street level. I do not correct horizontal convergence, as this will have the effect of rotating the object and give an en-face view point, even if I stood on one side.

Depending on the amount of correction, I may distort the object's proportions and it may look too wide or too tall after the correction. In this case I apply Free Transform on the whole image, and squeeze vertically or horizontally, to restore correct proportions.

I do not have experience correcting panorama images. It's probably more difficult since each frame has it's own distortions, and they may conflict with each other.

In this particular image, I think the only problem is with the right turret which seems out of line with the rest of the building. Application of Transform-Skew to just the turret can solve the problem.

I uploaded two images I took last month, on a visit to Berlin (to Moshe Ronen 1 folder). In one I exaggerated perspective on purpose, to give the feeling of height and in the other I corrected perspective, as it seemed to me to be more appropriate.

Moshe,

with PTGUI you can easily adjust both perspective and projection. The projection can be rectilinear (as is the case here), cylindrical or spherical. You can adjust the perspective be moving a point on the image and by appyling a rotation.

See my other image (Cathedral of Salzburg 2) for a further variation.
