We've been presented with a roll of film for scanning - about 45
years old, Plus-X film that's uncut and tightly wound from being
stored in a canister for all that time.  We're having a hell of a
time getting it straightened to the point where we can run it

Now that Baboo _and_ Duggal have sunk below acceptable levels of quality
and customer service can anyone recommend a decent lab that still does
dip-and-dunk processing and non-digital prints? Anyone have experience
with L&I Color Lab on 17th Street?
