May I ask if anyone has a few sheets of the subject films they don't intend to use? I have a small DIY project for which I'd like to expose & develop for maximum density to use as a glass carrier negative mask for 5x7 & 4x5 negs. Three or four sheets would suffice. Film must be Ilford to control its thickness. I'd gladly pay for shipping via PayPal to zip 98027 in Washington state. I have some fresh film in the freezer, but I don't want to open it until I'm ready to use it. PM me if you can help.
