I just received my first film camera and I am doing some research about film shooting. I wonder if I can shoot some photos with a roll A, and unload it and replace with another roll (i.e if I want to change to higher speed film) and later load roll A back and continue shooting where I left?
Can I “resume” a half-used roll of 35mm film, after taking it out? YES, assuming you take it out correctly and your camera will allow you to.
I do this often and successfully. It is not difficult for me and my camera model.
Lets say i have a roll of 100ASA film (Roll A) in the camera that i have been shooting outside in the mid day sun. Later in the low light of the evening i find i need a roll of 400ASA film (Roll B) because there is much less light and Roll A is not going to be a fast enough film for what i want to shoot.
I look at my camera's film counter and see that Roll A is only exposed to frame 18, I push the release button that disengages the film advance lever so i can slowly rewind the film back into the canister. I can feel the moment the end of the film, the leader, comes free from the take up spool and i stop rewinding so that i do not rewind the film all the way back into the camera. (Every camera is different and some have auto rewind that you can tell to leave the leader out and not rewind it into the canister. Some cameras roll out all the film and then as you shoot it goes back into the the canister. You will need to figure it out for your camera).
I now know that i can open the back of the camera, i open the camera and take Roll A out of the camera. I make a note on the canister, or the container it will be stored in, with a marker that says "shot to frame 18" so i know that sometime in the future when i go to load another roll into my camera and i grab Roll A i can see that it is the one i had already partially shot.
I go on and shoot my Roll B, then some time later i find i am back in daylight conditions and i need a roll of ASA100. I locate that old Roll A and load it into my camera like normal, but i know from the note on the canister that it has been shot to frame 18.
I leave the lens cap on and find a place out of direct sunlight ( or wrap my jacket around my camera ) and shoot/advance until i get to frame 20, this gives me a buffer to allow for differences in loading so i do not double expose an important image. Ready to shoot.
Presto magicko, i am shooting the rest of roll A.
You can, but it's a pain. It's simpler to get another camera body.
- You have to take care not to "lose" the leader. Otherwise, you have to fish it out.
- You have to keep track of the frame number.
- If not careful, you may double expose frames or shoot overlapping frames.
- Firing the shutter to advance the roll is time consuming. Depending on the camera, you may induce repetitive strain injury.
- Light leaks around lens caps may ruin previously exposed film.
