How to Load 4x5 Sheet Film into a Holder

Quick answer

Load 4x5 sheet film into a holder in complete darkness by opening the film box, removing the dark slide, inserting the sheet emulsion-side toward the lens, and closing the holder. Always handle film by the edges to avoid fingerprints.

Step-by-step: Loading 4x5 sheet film into a holder

1. Prepare your workspace: Set up a clean, dry surface in a completely dark room or changing bag. Have your empty film holder, a dark slide, and the film box within reach. Wash your hands to remove oils. Even a tiny light leak can ruin a sheet. Check your changing bag for holes before starting.
2. Open the film box in total darkness: Carefully tear the tape seal on the film box. Remove the inner foil pouch. Do not open the foil until you are ready to load. If using Ilford Ortho+ 80, you may turn on a deep red safelight now; for Kodak T-Max 400, remain in total darkness. If you are loading both film types, do not rely on safelight—stay in total darkness to avoid fogging T-Max.
3. Remove the dark slide from the holder: Hold the film holder with the dark slide facing up. Slide the dark slide out completely and set it aside. The holder is now open and ready to receive film. Never force the dark slide. If it sticks, check for debris on the holder rails.
4. Pick up one sheet of film by the edges: Locate the notch code on the film sheet (usually on the top-right or bottom-left corner). Hold the sheet by the edges, avoiding the center area. The emulsion side is the side that feels slightly matte or has the notch code in a specific orientation. Fingerprints on the emulsion will show up as dark smudges in the final image. Handle only the edges.
5. Insert the film into the holder: Slide the film sheet into the holder with the emulsion side facing the lens (toward the side that will be exposed). Gently push the sheet until it seats fully under the holder's retaining rails. Do not force it. If the sheet does not slide in easily, check that the dark slide is fully removed and the holder is not damaged.
6. Close the holder and replace the dark slide: Once the film is seated, slide the dark slide back into the holder until it clicks or stops. Ensure the slide is fully inserted so no light can enter. Repeat the process for the second side of the holder if it is a double-sided holder. A partially inserted dark slide will cause light leaks. Double-check the slide is flush with the holder body.
7. Store the loaded holder safely: Place the loaded holder in a light-tight bag or box. Label it with the film type and ISO if you are using multiple emulsions. Clean your workspace and repeat for additional sheets. If you loaded T-Max 400, note the expiration date (06/26) so you expose and develop it before that time for best results.

Film options for 4x5 loading

• Ilford Ortho+ 80 4X5 - 25 Sheets: Ortho+ 80 is an orthochromatic black and white film from Ilford, ideally suited for landscape photography. Its blue and green sensitivity allows handling under deep red safelight conditions. You can load Ortho+ 80 under a deep red safelight, which makes the process easier for beginners, but be aware that red and orange tones in your scene will appear darker with stronger contrast.

  

• Kodak T-Max 400 4x5 - 10 Sheets (EXP: 06/26): Kodak T-Max 400 4x5 is a panchromatic B&W negative film with ISO 400, very fine T-grain emulsion, high sharpness, and wide exposure latitude. Because T-Max 400 is sensitive to all light, it must be loaded in total darkness. Its wide latitude forgives minor exposure errors, making it a reliable choice for available-light large format work.
