[Leica] 20D B&W

By burning in I just mean either creating a multiply layer and darkening
that way, or just using the burn/dodge feature...

Forgive my simply questions again ...

Burning in ... would you be using a similar technique that Phong uses to
get rid of the blue in his snow, only other adjustments rather than
color correction?

In my case, I think it was the last scenario you mention below.

During my skating shoot last weekend I forgot to put the camera back on
manual for one team. I had been shooting something else and didn't have
to worry about the ice. The shots with _only_ ice background suffer from
underexposure and the noise was beyond help.

Interesting though ... if there was the slightest bit of bleachers in
the shot, the matix meter took care of it and those shots turned out
just fine. Otherwise I just run on manual. It's not like the lighting in
an ice-rink changes very much.

Thanks!
Daniel
