![]() Simply bypassing the hazardous color stop bath and going into the ECN-2 bleach will oxidize the color developer remaining in the emulsion, and cause severe staining to the film. Heat and any acid added to the ferricyanide bleach can liberate highly toxic cyanide gas, along with the forming of Prussian Blue deposits on film, reels and tanks. In addition to PPE, industrial exhaust vents are needed to carry away dangerous vapors and provide for the safety of the lab operator.Įmulsion acts like a sponge and carries color developer into the acidic color stop bath, generating poisonous hydrogen sulfide and sulfur dioxide fumes. Motion picture processing machines use caustic chemicals that you don’t want in your home, such as sodium hydroxide (lye) and sulfuric acid (battery acid), which can cause chemical burns from handling. ![]() Above right: Photo by The Brothers Wright on Kodak Portra 400 processed with Cs2 Cine Simplified. Proper ECN-2 processing requires special laboratory equipment and additional safety measures that can’t be attained at home.Ībove left: Photo by Henry J Keith on CineStill 800T processed with Cs2 Cine Simplified. C-41 processing was designed for darkrooms and mini-labs alike, for printing on RA-4 color paper.Īlthough the formulations have varied slightly between manufacturers (whether it be Kodak C-41, CineStill Cs41, Fuji CN-16, Konica CNK-4, AGFA AP-70, etc.), it is by far the most accessible color film process. The motion picture process involves a specific mechanical and chemical process for motion picture labs to produce long lengths of motion picture negatives, which print consistently on ECP-2 print film for projection. Let’s start with an important and often asked question: CineStill originally released Cs41 Color Simplified C-41 Kits. 6 Would I be better off just trusting in standard photo lab processing and CineStill Film?.5 Then why not just process motion picture film with Cs41?.What does it matter if we are scanning our film? 4 I’m not printing my negatives in the darkroom.3 Isn’t processing CineStill color film with C-41 chemistry technically cross-processing?.2 Why does Hollywood still use ECN-2? I heard that it was more advanced technology….1 CineStill originally released Cs41 Color Simplified C-41 Kits. ![]() A deeper dive into CineStill Simplified Cs2 chemistry: ECN-2 + CINESTILL = ? - EMULSIVE Close Search for:
