Richard,

Thank you, AFAIK Mukti-Exposure and/or Multi Scanning are independent  
of HDR, at least with my Silverfast I can decide how many multi scans  
I do (I can go to 16), and also Multi Exposure (I can go to 2 times),  
I normally use 4 to 8 multi scans and 2 for multi exposure, I'm still  
in training period...

cheers
Lluis
