Huh! I guess my clicking on it alerted the copyright police... It was a very 80's rendition of Laurie Anderson's Excellant Birds.
Yeah, you got the idea of checking exposure--except that it would be a lot more useful if you knew the speed of the lens and shutter speeds. If'n ya know the names, I'm sure you can look it up.
I don't know about over/under exposing--it probably depends on the stock. I guess I'd tend to a little under exposing. For your porpoises, probably doesn't matter too much.
