We still process slide E-6 slide film, but no longer can put them in to slide mounts for projection as we used to do.  The firm that made our slide mounters (Loersch) went out of business in 2011.  For several years, we were able to find slide mounts to work with here and there, but the supply was inconsistent and we finally had to give it up.  You can still buy mounts from companies such as Geppe and mount them yourself. At Old-School Photo Lab, we utilize small-batch processing. We spool each roll by hand onto a reel and put it into a light-tight development tank that holds four to eight rolls of film depending on type/width. Fresh Fuji chemistry is used for every batch of film, so the results are always consistent.
