For the darkroom users, Lynn Radeka http://www.radekaphotography.com/ Contrast Masking system is a way to get photoshop like effects on darkroom prints. I have the complete system with the carrier, hole puncher, trans film, CD, book, and I will even include an unopened pack of 50 sheets Arista II 5x7 litho film.
Great for 6x7, 4x5 and even 35mm work. $200 + Shipping at cost. Paypal OK.
