When you exposed the Konica with an R72...  what were your fstop and shutter 
speed settings?  I'm using about f11 with 1/60 or 1/125 for my first try but 
I'm new at this so let me know if that is wrong!  And I'm going to try it w/ 
a red first because I only used the red25 with a P&S but now I finally have a 
manual camera so I'll try the red25 with those settings.. unless I'm way off  
;-)

Thanks!
