How to Load Film in Any Camera: 35mm, 120 and Instant

Point-and-shoots skip the fiddly part. You pull the leader to a marked line or graphic near the take-up spool instead of threading it into a slot, close the back, and the camera winds to frame 1 by itself.

On most point-and-shoots with an LCD counter, the counter only starts counting shots when film has loaded correctly, according to Cameras By Max, and The Darkroom says an E on the LCD means the camera still thinks it is empty. Electronic SLRs with auto-advance load almost exactly the same way and usually have a rewind button, so you can rewind a roll early to switch film.

1. Open the back with its latch and drop the canister into the chamber.
2. Pull the leader until its tip reaches the marked line, keeping the film flat over the gate.
3. Close the back. The motor winds the film on and the LCD counter changes from E to 1.
4. At the end of the roll, the camera rewinds the film into the canister on its own.

Older rangefinders such as the Leica III, Canon rangefinders and Soviet Zorki and FED bodies load through the bottom: take off the bottom plate first and do not force the back. Canon's Quick Load (QL) models, such as the Canonet QL series, have a built-in clamp that secures the leader automatically.

On any manual camera you can also reverse the order. The Darkroom recommends a leader-first method: slot the leader into the take-up spool, then pull the canister across into its chamber. Most other guides put the canister in first, and both end with the same rewind-knob check.

The Pentax 17 half-frame camera is wound with a lever and rewound with a crank, and it can rewind a roll midway. You set the film speed by hand. Ricoh's instructions say to load it in a dark location, which is stricter than the shade most guides ask for, not to open the back until the film is fully rewound, and to tell the lab the roll was shot half-frame. It runs on one CR2 lithium battery, which Ricoh rates for about 10 rolls of 36 exposures with half the shots using flash; rechargeable CR2s are not compatible.

Instax. Check that the counter shows S, which means the camera is empty and safe to open. Line up the yellow stripe on the cartridge with the yellow mark in the film compartment and let it drop in; Fujifilm says never to force it. Close the door, switch the camera on and press the shutter once: the safety sheet comes out and goes in the trash, and an Instax Mini counter then shows 10. Opening the door with film inside resets the counter, and Fujifilm lists it as a usual cause of blank, white or all-black photos. The Instax Mini 12 review covers that camera in detail.

Polaroid i-Type (Now, Now+). Slide the pack in belly up, with the sticker facing out, until it clicks. Close the door and the dark slide ejects. When the pack is empty, pull it out by the sticker tab. Polaroid suggests keeping film in the fridge but taking it out about an hour before you shoot.

Polaroid SX-70. Unfold the camera, press the small yellow tab on the side to drop the film door, slide the pack in and close it; the dark slide ejects. Analog.Cafe suggests testing a vintage SX-70 with an empty pack and a dark slide before risking a full pack. Which pack fits which camera is in the Polaroid film guide.

Loading film takes no tools: a roll in the right format and, for many cameras, a working battery. Two optional extras rescue a roll when something goes wrong. Prices are from US camera stores, checked on October 28, 2026.

• Film. Kodak Gold 200 in 35mm (36 exposures) is $8.99 at Glazer's and K&M Camera and $9.25 at Pictureline; Kodak UltraMax 400 is $9.95 to $10.49. In 120, Kodak Gold 200 is $7.99 and Portra 400 is $15.99 at Glazer's.
• A battery, if your camera uses one. At Glazer's an LR44 button cell is $2.95, a 4LR44 is $3.95 and a CR2 2-pack (the Pentax 17 takes one CR2) is $16.95. Look up your camera's cell in the film camera battery finder.
• Instant film. An Instax Mini twin pack is $18.17 for 20 photos at Glazer's, about $0.91 each. Polaroid Color i-Type is $18.99 for 8 photos at Polaroid's US store, about $2.37 each.
• Optional: a film leader retriever ($12.00 to $29.99) pulls a leader back out of a canister without opening it.
• Optional: a changing bag ($32.95 to $42.99) is a light-tight bag you work inside with your hands, for freeing a torn or jammed roll in total darkness.

Kubus Photo, a Brooklyn lab, estimates that loading failures hit 15-20% of true beginner rolls, the most common first-roll disaster. The usual causes are below.

• Leader not hooked, or sprocket holes off the teeth. The take-up spool turns but the film stays in the canister.
• Skipping the rewind-knob check. On a manual camera it is the easiest sign, while you shoot, that film is moving.
• Opening the back before the film is rewound. Rewind until the tension drops first.
• Loading in direct sun. Shade or indoor light is enough.
• Forgetting the ISO. A manual camera's meter only knows the film speed you set.
• A weak or dead battery. On electronic bodies it can stop the shutter, and the lever will not wind until the shutter fires.
• Forcing the lever at the end of the roll. When it stops, rewind.
• 120 slips. Start arrows not lined up, backing paper loaded loosely, the empty spool left on the wrong side, or winding past the start marks.
• Instax slips. Forcing the cartridge instead of matching the yellow marks, or opening the door with film inside.

Most problems show up at the advance lever or the rewind knob. Match the symptom to the fix below, and never force a lever or crank that has stopped: torn film can only come out in total darkness.

Your negatives show whether loading was the problem. Kubus Photo says 5-10% of the rolls it sees come back blank because the film never advanced.

• Completely clear, with the frame numbers and maker's name printed on the edge: the lab developed it correctly and the film was never exposed. Usually a loading failure, sometimes a shutter that never opened.
• Black frames, with the black running onto the borders: light hit the film when it was unloaded or during developing, not in the camera.
• Overlapping frames: the film usually slipped on the spool during loading.
• Light streaks: old, sticky or crumbling light seals around the back door can let light in.
