Thank you! That makes sense. I just didn't know you had to have the menu open to do it.
Would the filename thing work for the other options where you choose fisheye? Like I set mine to equi something. I forget already what it's called. But it looks correct when I choose that over fisheye. Anyway, could I do the file naming thing with an "E" instead of an "F" for fisheye or does that only work with fisheye?
