The third gallery is the changing display. The show when we were there in late June was so cerebral that this engineer couldn't understand it..
If you are talking about the picturing Eden show, it's one of the best I've seen in a long time. A very good show with some great work.
Eastman house has undergone some changes in the last 10 or so years. They moved the gift shop and made it larger and added a cafe/coffee shop. The camera collection you saw was not a 'full-time' exhibit. There used to be a permanent equipment exhibit, but that is now where the gift shop is.
It depends how much of the collection is on display. Usually its not much though, depends on the other shows. There is no space dedicated to display images from the collection. But, if you have reason you can go into the archives to view works - if you are a student or doing research, etc.
But if the Eden show is still up, see it while you can. There is great alt process stuff, Starn brothers work, etc.
