WebAug 16, 2004 · In any case, a straight vertical wall, as you have, will "bulge" at the center in a cylindrical/spherical projection as that part is closer to you. That would be evidence of a flaw with a rectilinear lens (probably all that most of us will ever use with the possible exception of a fisheye), but it is a fact of life with a cylindrical projection.
