         I had almost the same thing happen to me when I last used an 
opaque IR filter.  The problme was, nto enough light.  I did  aseries of 
bracketed shots under cloudy skies, not full sunlight, witht he lens 
stopped down (I forget exactly where).
         Anyhow, the two tiem expsoures I did at 4 and 5 minutes had a very 
slight, underexposed image, but he rest was blank.
         I find Konia 750 very slow, and to that end, I woudl reccomend the 
Maco 820.  Faster, more sensitive to IF, nice film to work with, and it 
looks more like Konica than it does HIE.
         But back to the orginal thread - where to meter Konica 750?  REAL 
sloooooow.  As in under 10 ISO.  I think the film unfiltered is no better 
than 25 to 50, in my limited expereince.
