Once you get past that initial step, you have a bit more sensitivity. The astronomy folks have done it for years, in a very controlled fashion. As far as lenses are concerned, give me the flare free ones anyday. Just like with some other problems earlier lenses had, you can raise your base fog in various ways if you so desire, but getting rid of flare when you don't want it doesn't happen (at least if it obscures or reduces detail). * Henning J.
