The Kodak Kodacraft Roll Film Tank is a classic "daylight-loading" development system that uses a flexible plastic apron to separate the film layers, allowing chemicals to flow freely.
Loading Instructions:
Loading must be done in complete darkness (a darkroom or a changing bag) until the tank lid is securely fastened.
Prepare the Apron: Lay out the apron for your specific film size (typically 120/620 or 127). The apron has small nubs or corrugations along its edges to keep the film from touching itself.
Attach the Film:
Separate the film from its paper backing (for roll film) or the canister (for 35mm).
Align the start of the film with the end of the apron.
For many Kodacraft models, the apron has a small loop or hooks. Insert the film leader into the meeting point between the loop and the rest of the apron.
Roll Together: Roll the film and the apron together into a tight spiral. The film should be on the inward side of the spiral.
Insert into Tank: Place the rolled "sandwich" into the tank base. Ensure the metal plate (if included) sits on top to prevent the apron from floating up during agitation.
Seal the Tank: Secure the lid. Once the lid is on, you may turn on the lights.
Development and Agitation
Pouring Chemicals: Use the opening in the lid to pour in your developer, stop bath, and fixer.
Agitation: Unlike modern tanks, Kodacraft tanks are generally not inversion-style. Use a "figure-eight" motion on a flat surface or a slight side-to-side swirling motion to agitate the chemistry.
Washing: After fixing, wash the film thoroughly. Note that the apron may cause temporary edge markings on the film, but these will not harm the negatives.
