Digital BW, The Print

I have had really first class results by making negs through Photoshop
with the Pictorico film using Burkholders curves. www.danburkholder.com.

However that has been about 3 years ago and there is another
alternative method that some swear by that is described in a book by
Mark Nelson who contacted me about this a coupel of years ago. I have
yet to try it. Too many irons in the fire. Here is the link-

You should be able to fine tune excellent negatives with either of
these methods. Be sure to use good paper. For me that was the most
important variable, using the paper designed expecially for
plat/palladium printing.
