Tip: Film length for cutting

• With backing paper (from 120): approx. 78–80 cm for 24 exposures
• Without backing paper (from 35mm): approx. 80 cm for 24 exposures (without paper, slightly more film fits)

Light vs. dark: When can you handle what?

Never expose unprocessed film to light. Here, we clearly explain what you can do in daylight and what absolutely has to be done in the dark.

Allowed in daylight:

• Practice with a scrap piece of film
• Prepare the empty cartridge and backing paper
• Handle the still-sealed 35mm canister
• Handle the fully sealed cassette and place it in the camera

Only in complete darkness:

• As soon as the 35mm canister is open: pull out the film, cut it, and place it in the cassette
• Close the cassette

Only the sealed cassette is light-tight again. From then on, continue working normally in daylight.

Recognizing the end of the roll (end-fold trick, Bob Janes): Fold the end of the film over twice and tape it down; optionally place a toothpick in the fold. When the film stops advancing, the roll is finished. This only helps you recognize the end of the roll. It is not a trick for removing the film in daylight.
