Re: [APML] Another processing challenge!

You'll have to ask the people that did the scan if they had some
sort of auto levels turned on as part of the scan.  Take a look
at your negatives and see if the stars have more color and if
the bright clusters stars are smaller and less saturated.  If they
are, you could benefit from a 16 bit scan.

The TIF.  (Cable modem here)
