Doing my random rounds on ze web I stumbled across this neat little plug-in. Free stuff is always something you can never have enough of, so it’s certainly worth giving it a shot. I’m not sure if I ever had much practical use for this sort of thing, but I like that this isn’t just another squeeze & stretch aspect ratio conversion thing and they actually re-synthesize the image with some sort of seam-carving algorithm. Even the fish eye effect this can produce is kind of nice, though arguably it will only ever fully wow you on a large 4k monitor or something like that.
