This one is useful for pictures taken with the camera pointing slightly upwards or downwards, and when you want verticals to be rendered straight, yet preserving their convergence and thus the the upward/downward perspective. More recently, I've written a script to provide the. Mercator is my favorite: it's a kind of panoramic cylindrical projection that looks quite similar to the Fisheye-Hemi projection and is free of local distortions (mathematically speaking, it's a conformal mapping of the sphere). I use and the plugin, together with a few to convert the fisheye image into whatever projection better fits the subject: either rectilinear, stereographic, or Mercator. Is interesting, the guy fed an image of a grid pattern through the Fisheye-Hemi plugin and then created a warp transform in Photoshop that approximately matches the deformation on the grid. Fisheye-Hemi is superior to these, though, as instead of using a standard remapping to a rectilinear projection that softens the edges and requires an aggressive crop it uses a custom mapping algorithm that preserves much more of the original image and sharpness and still straightens out lines.īluesky Blf 1207 Manual.

I've been tempted to get a fisheye lens (The Nikon 10.5 DX specifically), and have seen the Fisheye-Hemi plugin for 'normalizing' fisheye images. The answer partly depends on what you are trying to correct for correcting fisheye-style wide angle lens distortion I really like a program called Fisheye-Hemi: That has just a few settings, but does a.
