Dear Jim,
Thanks for your order, I hope you're not too disappointed, I'll try to help if I can.
The essence of the workflow is that the nature of your source material actually doesn't really matter. The point is that you're making a kind of snapshot of your film, without interpreting the contents during the scanning process. You're making a kind of RAW file. I haven't tried this because I don't do B/W, but I think it should be possible to treat your film all the way as a color negative, and then do the B/W conversion at the end in Photoshop. The most important thing is that you capture all the information that the film contains, in the shadows as well as the highlights. ColorPerfect makes that possible if you follow the instructions in the guide. Please experiment with that and let me know how you get on,
Best regards, Gerard Kingma
