I have long been fascinated by the anamorphic image. And no, it's not the flares, or the oval bokeh, or things as overt as that. For me the biggest fascination has been what these lenses actually do to the image. Because, looking at movies by, for example, Luc Besson in his early days. I noticed that they were distorting in quite a weird way. It's not really a normal fisheye look. And even though the angle isn't that wide, it gets a wide feel.
So I set off trying to find out what it was and whether I could replicate it digitally from an image taken with a spherical sensor. I got some answers...
