Re: Correcting distortion in rectilinear wide angle lenses

I particularly am interested in the anamorphic corrections this software can do. This is for rectilinear not fisheye lenses it seems to me.

Quote from the review:

  1. Anamorphosis Tool. This tool corrects the geometric distortion caused by a wide angle lens on object at the far edges of the image. The typical example is a group of people. If the guys on the ends were holding plates, they wouldn't be circles but ovals. This tool makes them circles again (almost instantly). And restores the shape of their heads, too.

It's for special fisheye-like superwides, like the Samyang - not the spherical ones that are true fisheyes with circular images.

Note the wheel and instrument "circles" (like the plates and faces on the Image Trends web site

Presto! Round wheel, round instruments - and a straight backstay

I tried it on my 11mm images from my 11-16mm Tokina. Ugh. That great lens is not designed like the Samyang.

My conclusion: NOT for rectilinears
