400 asa in older folder?

[mdcarma]

I have a quantity of both, 400asa color 120 film, and old folder/TLR/box cameras. I also have a lab that will push or pull developing.  Will I get adequate results shooting 400 @ 100 and telling the lab to develop as 100? I'm assuming some of the older cameras with 1/500 shutters can handle 200asa? So far I haven't tried anything but 100 in all the single speed shutters, and they seem borderline over exposed.
Thanks.

Obviously the adjustable cameras will handle it with no problem at all, and the lenses will benefit from being stopped down. For the others, how 'bout an ND filter so you can process normally and get maximum quality?

Any camera capable of 1/500 in f16 will do for 400 ASA. Or 1/250 in f22. That is the exposure for sunny subjects.

If shooting B/W you may just slip a yelllow filter all the time, and you'll get by if the camera can do 1/250 in f16 (and the skies will be vastly improved at the same time).

With ND filters of course you may have a lot more flexibility using color film.

Michael, I've found that over exposing fast color film doesn't hurt a thing. In fact, some films actually do better with some overexposure. I once made the mistake of running a roll of Max 800 at 200 before I noticed I forgot to set the film speed. Some of the most beautiful colors and finest grain I ever got. You can always use a polarizer to bring the exposure down a couple of stops.

Seems to me Alan Gage got some nice results in the Shur-Flash Tour folder with ISO 400 film and a red filter (two stops filter factor, I'd guess, and it really pumps up the skies).  OTOH, I've shot TMY in a box camera, pulled it to 200, and it was fine (even though it was still technically overexposed two stops with that pull).  And I routinely do that with my Speedex Jr., which has a minimum exposure of 1/25 at f/32 (which would be Sunny 16 for ISO 100); EI 200 and a one stop pull give nice results indeed.
