As a general rule of thumb, I'm inclined to treat outdoors, plenty of moonlight as shadowy illumination, or a 20% miss chance for normal vision and no miss chance for low-light. I've never really considered the max range one can see, but its around however big the battlemat is.
Though I see hong has beaten to the punch on that one. Well played.
On a semi-related note, I've always wondered why elves and dwarves haven't come up with "non-magical" darkness spells (if that makes sense), since they would be able to cast darkness that would impair other vision types but that they'd be able to see through. As it is, having the opponents with vision mods (a little SR terminology there) casting darkness spells to cancel out light sources is a pretty good tactic against parties with regular vision types. The goal is to give the other team a miss chance while avoiding one yourself.
