Todd,
Yeah, it took me a long time to plow through most of the paper...I have not actually finished it yet either.
:-( But...I'm trying. An then there are the scientific parts that I don't understand, but hey, that's ok as
well.
On the OB front: I think that the larger one makes a print, the less important the extreme brightness becomes
(of course this could also be dependent on subject matter as well), and the less important a slight paper
texture makes.
In reading the above sentence over, it seems a bit garbled, but we had a big shoot today, and I'm feeling a
bit fried, sorry.
