RE: [Leica] tri-x: why I stopped using it

[chucko@siteconnect.com (Chuck Albertson)]

Are you talking about 35mm film? Tri-X Pan Professional (ISO 320, with a
long-scale curve) is only made in medium format (120/320). I think the Tri-X
Pan Pro you're referring to is good old Tri-X, with the "Pro" hooked onto it
as some kind of marketing flash.
