Understanding the Exposure Dial on Vintage and Modern Polaroid Cameras
The dial on the front of most Polaroid cameras has three or four positions, and the letters on them aren't arbitrary. They control shutter speed, which is the only real variable you're adjusting once the film is loaded. The rest of the time you're just hoping the weather doesn't change. S stands for Slow. On the exposure dial, it means the camera will hold the shutter open longer, letting more light reach the film. You use it in low-light situations: indoors, shade, overcast days, dusk. The opposite marking is usually H for High or normal daylight. Some cameras also have N for Normal. I bought a used Polaroid OneStep 2 last year with no instructions and spent three weekends burning through seven packs of film trying to figure out why every indoor shot came out either white or black. The problem was I was leaving the dial on H inside my apartment. H is for direct sunlight. Using it indoors is like trying to take a photo in a snowstorm when it's already dark.
Switching to S fixed most of it. But S isn't a magic indoor setting. It just gives you enough extra time for the sensor to gather light. If you're in a room that's dimly lit and you're holding the camera steady, you'll get a decent shot. If you're moving around, you'll get streaks. That's just how long exposures work. Here's what most people miss about these dials. The settings aren't precise enough to be technical. They're rough approximations. The camera's light meter is basic, usually a simple CdS cell, and the dial positions overlap. S might work fine on a cloudy afternoon and blow out on a sunny morning. H might be fine in open shade but ruin a picture at the beach. You learn by shooting and noting what each position does on a given day. Another thing nobody tells you: temperature affects both the film chemistry and the meter reading. I shot a pack in December at about 40°F and every frame came out grainy and underexposed even on S. The chemicals in the film don't activate properly below about 50°F. I kept the spare film packs in my jacket pocket against my body heat before loading them and the results improved noticeably. It sounds extreme but it matters.
If your camera only has one fixed exposure setting with no dial at all, you're at the mercy of the built-in meter. Those work decently in normal daylight but struggle in anything challenging. The dial cameras give you a fight, but they also give you a way to fight back. Common mistake: people treat S like a night mode and expect it to work in near darkness. It won't. The shutter speed on these cameras maxes out at maybe half a second or so. That's enough for a dim room with a steady hand, not a candlelit dinner table across the room. For genuinely dark scenes, you need a flash or you need to accept that the image won't expose properly. The workable range for S is roughly 5 to 20 feet from the subject in indoor lighting, assuming the room has at least a couple of lamps or overhead lights. Stand too close and the subject blows out. Stand too far and everything goes dark. I use about 8 feet as a starting point and adjust from there.

If you want consistent results, shoot one test frame at each setting in whatever lighting you're in. Compare them after they develop. Two minutes of testing saves you a whole pack of wasted film. Film costs about $18 a pack right now so skipping that step hurts more than it should. Some newer Polaroid models like the Polaroid Now+ have app-controlled modes that automate exposure. That's convenient if you want point-and-shoot simplicity. But you lose the ability to override the meter when it makes a wrong call, which happens a lot. The manual dial cameras force you to think about light instead of trusting a cheap sensor. Bottom line: S means slow shutter for low light. Use it inside or in shade. Don't expect it to work in total darkness. Test your lighting before committing a full pack. Keep the film warm in cold weather. And remember that these cameras are forgiving but not smart, so the settings are more suggestions than commands.
