I've noted that quite a few people who share an interest in cameras and photography also seem to have an interest in firearms. Look around this site a bit and you'll see what I mean.
 
I don't know if you could consider cameras or firearms as an artform but both devices seem to have a similar cachet. As well, any really well made device, perhaps a Stanley hand plane from the '30s or '40s, a Winchester 94 from the same time, a Leica iiif, my little Welti 1, etc. etc.
 
For me now, pointing a telephoto at a critter is as far as I'll go. I'm fortunate in that I live near one of the world's largest wildlife parks. (15 minutes drive) 
 
My background is of a fairly extensive technical nature. As I think of retirement I'm considering doing camera restoration. I have the tools and soon I may have the time. I don't want to get too industrial about it, but, if I make a few bucks in the process thats good.
 
So far I've only done CLAs. I've set up a jig with a frequency counter and a photocell arangement for shutters which is more than accurate enough. I have a nice little lathe with which I've made a few parts. I'm in the process of building a lens collimator which will be much cheaper than buying one. Silver soldering seems to be important for repairing some shutter parts and I can do this as well. As I need stuff I get tools from "Micro Tools" and watchmakers suppliers.
 
Working on the old stuff is fascinating. I'll concentrate on complete restorations of early cameras and avoid SLRs and digital stuff. 
 
It looks that you've come a good long way toward this. I think that we will see more and more people turning to restoration of things like cameras, tube radios, tube amplifiers, furniture, guns etc.
