Re: OT:EV comp for snow

[Mark Cassino]

I usually spot meter on something that is close to 18% grey (a grey card 
would be good, but I usually use a tree trunk.)  Note the reading, turn 
around and meter the snowy scene, note the different and add enough 
compensation to bring the second reading in line with the first.  After 
that , your meter is more or less calibrated for the snow.  Should be +1 to 
+2 stops depending on how bright it is. of course, do the first reading on 
something in the same light as the snowy scene, and not in a shaded area or 
something.

                A co worker is heading for a ski vacation in Europe this 
weekend and has a
bunch of
Velvia and Provia 400F. We were talking about metering for bright 
snow,which methods,hand
held,gray cards,back of hand etc.One i thought of,and his camera can do it 
is work with
EV.
He seems to want to shoot in a program mode of some sort and I dont use EV 
at all,but i
said i would
check this for him.
If he uses the program mode and its bright snowy day,his camera will try 
to undewrexpose
the snow.I
suggested using+1.5 or +1.7 EV and that should help.

Did i send him the right way.?

Myself i would do it manually with a hand held reading,but, you know kids 
these days. :-)

I'll fwd any response to his email.
Thanks in advance
