i heard Digital ICE only works with color negs, is it true?  i also
heard web mount scanning can resolve the dust problem on film, is it
true?  if so, can my Epson 4870 scanner do web scanning and how?
thanks.

I want to equip to do motor sports photography, specifically sprint
dirt track racing. Most of the action is at night, so I need a capable
strobe setup. The other photographers are using Lumedyne or Norman
400w/s units, some with large Norman reflectors.

Could someone let me know how I can get a conversion of B60 (or B50,
etc) to its equivalent size in mm?
Thanks!!
