This developer produces negatives with normal contrast and extremely fine grain. These negatives can be enlarged 25 times without noticeable grain in the print. Modified POTA gives better tonal separations with slightly higher contrast than regular POTA. Film speed is 50-80 ASA. The kit makes 1 liter of working solution which has a life of 1-2 hours. Solution Size Cat. No. Price 1 liter 01-0075 $9.25 FORMULARY TD-3 TECHNICAL PAN FILM DEVELOPER An original formulation by William Tropp, is a unique, non phenidone based film developer offered exclusively by Photographers Formulary. This developer, when used to process Kodak Technical Pan yields negatives with unique clarity, high acceptance, and superlative low contrast gradation. With TD-3 development there is a true increase in film speed of more than one stop when compared with most developers. The combination of Tech Pan film and TD-3 allows grainless 16x20 prints to be made. An average of 36 rolls of film can be developed with the small kit, 72 with the medium size kit and 144 with the large kit. The shelf life of the stock solutions is one year, the working solution is used only once. Shipped as a liquid concentrate. Solution Size Cat.
