The last of the fisheye shots, a straight fisheye this time. Thank you for your patience. Lake Conestee Nature Preserve, Conestee, SC

Another fisheye photo de-fished with the "corner stretching" method described in the previous post. Lake Conestee Nature Preserve, Conestee, SC

This is a fisheye photo de-fished in software, but it is not de-fished to emulate a rectilinear lens as in some earlier posts. In this one, the corners have been stretched out to the left and right until the vertical lines are straight up and down. In the vertical direction, it still retains the original fisheye projection.

In the fall of 2020, I decided that my widest angle lens was not quite wide enough for some of the architecture shots I was attempting. As I was researching wider lenses, I found that some people were using fisheye lenses and then "de-fishing" them in software to achieve wide angles of view. I thought "I can do that."

 

So I bought a fisheye lens, and I wrote an app to de-fish it. (Trigonometry!) It was a fun: both from the photography side and from the coding side. The next ten posts will be pictures from that time, some de-fished and some not. In the end, I got tired of the fisheye and sold it. But I learned a lot.
