Subject: [filmscanners] Re: Flattening negatives

I agree with nearly everything you say, but one thing is different:

My slide films are (slightly) curved, when developed in a dip- and - dunk- processor, 
and they are completely flat, when developed in a big lab with roller machines...
I made this experience (and the others regarding scratches and dirt, too :-( ) with
several labs of each kind.
I never found a dip- and- dunk- lab that could deliver the films as flat as they come
from the roller- processing lab.
