Many thanks for the kind and supportive thoughts. They are appreciated. I'm ruefully aware I can get a little evangelical about emulsion making. I keep hoping to hear that someone else has joined the club. But it may be that the APUG group is a tad too conservative. B&W paper is seen as something that comes in a package from a factory. The way it always has been is the way it oughta be (I really am saying that with smile on my face. I respect the intent of APUG's mission.)
Because I do respect it, and sincerely respect Sean's right to keep out digital, I am very uncomfortable posting anything here. APUG should be the natural place for this dialogue. But, because I am incorporating digital negatives (scanned from film) into my research and work flow, I should not be posting here and will not again.
I will continue posting updates and answering any questions I can about silver gelatin emulsions on hybridphoto.com. If you haven't visited the site, you really should. I'm pretty sure it's not a sin. Great folks there with a genuine love of photography - past, present, and future.
