Fisheye “defish” control

Defishing in Capture NX2

Nikon Capture NX2 includes two ways to correct the 16mm f/2.8 fisheye for the inherent fisheye distortion: the Fisheye Lens control (covered by this page), and the Distortion Control facility. I generally prefer the Distortion Control.

The Fisheye Lens control is specifically and only for a fisheye lens. It can be used to “defish” a fisheye image into a rectilinear one.

Using the control is easy: just check the box and wait for a while (on my machine this can take minutes, due to an Crapture NX2 bug, it tends to happen on 8-core machines with lots of memory).

Defishing naturally crops off a lot of real estate, so check the “Include areas where there is no image data” checkbox, and crop and/or fill in as you see fit.

Mouse over/out to compare the fisheye vs defished image.
