There are two Tri-X films and they are different emulsions with different characteristics. Tri-X 400 is considered to be an amateur film by Kodak and is available in only 135 and 120 formats. Tri-X professional is available in only 120, 220, 4x5, 5x7, and 8x10 formats.

I then downloaded the latest Kodak datasheets and found to my amazement, two Tri X emulsions, TriX 400 and 320, which are available in different formats. I cannot begin to understand the weird reasoning behind this but would welcome any observations between the two emulsions. It would also seem that TriX 400 is not available in 5x4! --=20 Regards Chris Woodhouse =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there. ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
