Someone posted an ad on the local Craigslist saying he'd bought some old glass negatives and wanted to find someone who could contact print them. I e-mailed back, sure, I can. So, now that I've started printing these, I'm more and more curious about what it was like to do this "back when". I don't know exactly when these were taken because I don't know the landmarks in them. I'd guess early 1900's, maybe late 1800's based on the clothes I've seen. There seems to be a range of subjects and photographer's skill. They could cover a wider time period, too. What speed would they have been? Would most people have coated their own or could they buy them? Would the emulsions have been kinda similar to what we have now? How many people were using glass negs? When did they first start being used? I've really only dealt with film and got into it in the 70's as a kid, so I don't know much about the history of photography (besides the really big names). Feel free to go off on informative tangents.
