Deliberate distortion.

The enlarger is not there just to correct distortion but to add it as a compositional tool, in some cases to comic effect. The most obvious way of producing this is to bend the paper by clamping it between two blocks in a convex or concave shape. Double curves are possible. Remember the effect  aperture has on the depth of field and allow for it by using a larger F number to compensate and don't lose sight of the fact you will need to use dodgers to adjust the relative exposure.
