Re: filmscanners: 48-bit batchscanning

If you want to make tonal and color adjustments later you're better off 
retaining 48-bit files.  Change to 24-bit is like rounding off numbers, the 
low-order data is lost: for example you can change 1.04 to 1.0 or to 1 but 
changing it back will yield 1.00.

You should have no problem resampling down to a thumbnail size in PS, and it 
will be faster than rescanning.
