Using the FishEye Lens as a normal wide angle

One of the most creative tools in photography is the FishEye Lens. It often provides that unique vision which takes an image from ordinary to extraordinary. However, sometimes a FishEye can be used as a rectilinear normal Wide Angle lens. Many programs provide a “de-fish” tool which crops and straightens a FishEye image into a traditional rectilinear image. Here is an example of where the different (in FF FOV) a 15mm FishEye was the only way I could get this image as my 18mm “normal” WA was not wide enough.
