[Leica] Be's Soccer Game

[mark at whitedogs.co.uk (Mark Pope)]

Bob,

IIRC the correct way to use the expodisk is to use it like you would use 
an incident light meter.  So the best method is to go to the subject and 
then point the camera towards the taking position: something that's not 
always feasible.

We went to the Crufts dog show on Thursday.  The Lighting in the 
National Exhibition centre is just plain awful. A mixture of tungsten (I 
think), daylight and some flourescents for good measure.  I didn't take 
my expodisk with me (D'OH!) and the colour balance on many shots is 
wierd to say the least.  I am seriously minded to forget about trying to 
make colour shots and just do B&W conversions.

BTW - if anyone disagrees with the expodisk method above, by all means 
shout!
