I have been thinking over the idea of starting a set of tutorials on photo system design as I learned it over the years at Kodak. With the dwindling number of engineers out there, and so few who want to participate in this type of discussion, I thought there might be people out there interested.
I did start one on PN a while back, but it was largely ignored so I stopped.
So, here is the question, and if the answers are favorable (and there are enough of them), I would start it and ask Sean to create a sub forum on system design for B&W and Color. In addition, I would consider a sub forum on the design of photographic processing solutions, Color and B&W.
This will not be a non-technical series. It will take some thought to understand what is being described and it will take people willing to learn a bit of chemistry, not much but enough to follow some discussions.
I suspect anything you present will be more than worthwhile, but I'm wondering, when you say, "photo system design", are you talking about coating machine design, processing machine design, other?
Regardless of what specifics, I'm thrilled any of the hard won knowledge gets saved and searchable.
I don't know if you get over into the largeformatphotography.info forum but one of the guys over there is quite intent on producing a e-zine with hard copy follow up every three months as wanted. It seems like a good topic for the new site to debut in January. Of course that's besides here as well.

Slight deviation of topic, Wayne that e-zine has had a greater following on APUG.
I am quite interested in the chemistry of going from particles of silver to an image on film; so from sensitization through to finished negative/positive. However, everytime I start to think about it, I realize that I haven't really thought about redox chemistry in about 20 years and that I have forgotten things I really need to know to understand it.
Just a suggestion, but perhaps Sean could work out a way of building some kind of knowledge base with linked forum posts, so the actual main content is separated from any potential hijacking. A set of tutorials is an excellent idea.
It sounds interesting, and valuable to have that discussion. I'm interested, both in the photo system and in a discussion on processing solutions. I've got a couple of engineering degrees, so I'm sure I can study up and follow the chemistry.
What might be most interesting is not just how things were designed, but why. Some of that 'why' might help others scale the process back down to what would be a feasible size today. I know you are doing that on the home darkroom size already. I'd do my best to match your investment of time in writing it with time studying and learning.
