Hi all,
After a year or more of kicking the idea around of shooting 4x5, I'm almost ready to go. I've built a 4x5 pinhole camera out of an old copy(?) camera and now I need film holders.
The camera has a graflok'ish back that will fit one of those film holders that holds 6 films. I know because I found an old broken holder and tried it out.

Besides that kind of holder (called...?), what about regular single/double sheet film holders? Will I be able to use them? Are there brands/types of these holders that should be avoided?

Thanks,

BTW, that pinhole camera project can be found here: http://stevemphoto.typepad.com/photo...4x5thingy.html
