Hello all, I read that the best effect with star filters is achieved
against a dark background (night in my case) and with a relatively
short exposure. Anybody know what "short exposure" would designate in
this case? Also, do "stars" have an optimal f-stop? I'm trying to make
a recipe book so I'll know what to "feed" my filters. I know, bad
humor, oh well. Thanks to anyone with info on this. And in a few
hours, Merry Christmas to all!!! Happy holidays, Michael J.
