James: I don't know what all your reasons are for using ortho film (one not
metioned below is the ability to develop by inspection under red light), but
if the old-time look is the main thing, then consider that using a blue filter
creates the same effect. A particular blue filter is specified in The Film
Developing Cookbook (#85?), but any filter that's blue blocks red light,
so.... Using a blue filter with pan film instead of the red-blind film has
some advantages, notably that you can rely on the well-known characteristics
and developer-compatibilities of pan film. Information on development
of ortho film seems to be quite a thicket. Still, for all I know, you may be
dealing in the main with availability/price of great big film. If so, I'd
point out that you can almost certainly get FP4+ and HP5+ cutoffs from Photo
Warehouse at very reasonable prices. I've been getting it for 7x17. -jb
