Your best bet is to join the Yahoo Dye Transfer Group - Jim Browning moderates it and if you are serious about trying dye transfer it will provide you the resource material that you will need. The group is pretty much like APUG in that there is a great deal of technical information available to you from the members and they are willing to share much like here. The process is far from dead yet with a number of people still using the process although there are only a small number that do it on a commercial basis.
