      Hi folks,
      could someone please give me a hint how i can re-convert an equirectangular image (360x180) back to a donut-shaped image (with limited fov then)? I would like to get an image resambling an image coming from a parabolic mirror (eg. 0-360). Within Photoshop (Flexify) or PTGui or ...?

      Thank you!

                  I found when making a special version of SPi-V for my 360 One VR that the image coming from that optic looks a *lot* like an ideal (circular) fisheye projection with a high fov. That should not be too hard to create with PTGui or the Panotools filter in photoshop, or even using the Polar Coordinates filter. And then you add a dark spot in the center...
