How can I achieve this effect? Lens compression does not directly have anything to do with the focal length of a lens, though it may seem that way. In fact, it has everything to do with the distance ...

How can I edit equirectangular images?

ImageMagick can't do this—it doesn't do projection remapping. But there are a number of other tools that do. I'm pretty sure that Hugin or panoramas tools scripting or Gimp and Mathmap could ...

What makes RAW files difficult for manipulation?

There are better formats for lossless, high bit-depth image storage and exchange. The main benefit of raw files is that they contain minimally-processed sensor data. So there's no compelling reason ...
