[Leica] Using Noctilux with SF20

[Rick Dykstra <rdandcb@cybermac.com.au>]

Hi folks,

I've been invited to shoot a Ball tonight - the end of week ball for a
convention of the Royal Scottish Country Dancing Society.  Should be
lots of interesting photo opportunities - colourful kilts, movement,
shiny buttons on jackets.  I'll be trying for some slow sync flash shots
of the dancers, to get that blurred background effect with subject
movement and a little flash induced snap freezing with reflections.
Might use the R8 with second curtain sync for this.  Second curtain sync
with an M camera would be better, to enable easier tracking of the
subject during a longish exposure.  Put that on the wish list!

I'll also be taking portraits, in fairly dim light.  For these I want
minimum flash effect, if used at all. Question is, has anyone had
success using their Noctilux or a 35 or 50 Summilux wide open with the
SF20 for minimum fill?  What did you set the flash on?  I'm thinking
I'll expose for ambient and dial in -2 or -3 EV flash or so, to avoid
overpowering the ambient look. 

Any thoughts?   

Regards
