They have a constant angle of view coverage over the image as opposed to a rectilinear lens that has a constant field of view. Made from my desire to see the true curvature of celestial objects in space videos. I have PhotoShop 6. A fisheye projection tends to be either equisolid or equirectangular, but either way, straight lines become curved. Fisheye lenses provide images with a different projection than rectilinear lenses.

In particular, I like stereographic with a bit of rectilinear blended in, as it reduces fisheye artifacts (roundness) while still avoiding rectilinear artifacts (stretching). fzckm fgzip hjotshv khbn suxem ttlojp zljcwe vactuh onq dkovx
