I grew up during the "Transitional Period" and rise of digital, so the entirely pre-digital professional era of photography was just before my time, but I have since met and associate with a wide number of professional photographers who were active during the 90s and through the industry shakeup.
They all seem to fall in one of a few groups:
- They didn't get rid of their film gear in the transition to digital, they transitioned to specialized film work. [Smallest group?]
- They've packed their gear away, possibly using it, but now mostly just sits on a shelf looking pretty.
- They held onto their gear initially due to being on the fence, but then sold it for cheap while everyone was dumping 'useless' gear trying to get what little they could for it. [Sadly I think I was busy trying to pay for university at this point, and missed out on a LOT of really nice gear. Was also before I realized I wanted to play with film anyway...]
- Decided to make the switch early, sold their gear while it was still worth early market value. [And bought in on early and probably paid a heft early adopter tax on their initial digital kit.]
- Decided that the value of the space the gear was taking up was worth more than the gear itself, and gave it way/sent it for scrap.
Sadly it looks like a lot of enlarger and other processing gear, and some large format cameras, eventually fell into that last group.
