I converted some of Helen's ORF to DNG, and it saved space. Don't know if I 
lost anything. When I convert Tiffs, they end up much larger, but seem to go 
from 8 bit to 16 bit files. Can someone explain whats happening? I am 
scanning my slides, and would prefer the files to end up around 10 to 20 
megs, the size of my DMR M8 files, but they are coming in at around 50 megs 
in Tiff.

I do not see any real advantage of doing that. Besides, if you select  
the option "convert to DNG and import" in Lightroom, it does not  
actually convert TIFF files--all it does is make a copy in the  
directory where it keeps its DNG files.
