How many photos are on a roll of film?

How many exposures are on a 35mm roll?

The common sizes are 24 and 36. This is 135 film, the cassette format whose frame measures 24 by 36 millimeters, and Wikipedia lists the history and sizes under 135 film. Shorter rolls of 12 exist, and the 36 count is the one most people picture.

You often get a frame or two extra. Loading leaves a little unused film at the start, but the count printed on the box is the guaranteed number.

How many shots does a disposable camera have?

Single-use cameras vary by maker and model, and many sit around 24 to 27 exposures. Check the counter on the body or the printed number on the box. Wikipedia has a history under single-use camera.

A disposable has no way to add frames. When the counter reaches zero, you stop. That hard limit is the whole idea, and it is what a digital disposable camera app tries to copy.

How many frames does a Proofsheet roll hold?

You choose 12, 24 or 36 when you load the roll. Free rolls are 12 or 24 frames, and the 36-frame size is part of Pro. The week roll is fixed at 24. A small LCD counter on the camera shows how many frames are left, and when it reaches zero the roll is finished.

Proofsheet is not on the App Store yet. These numbers describe the app as built.

Which roll size should I choose?

• 12 frames suits an evening, a walk or a first try. You think before every shot.
• 24 frames suits a day trip, a full party or a week roll.
• 36 frames suits a whole weekend or a long wedding day, and it needs Pro in Proofsheet.

Why does the number matter?

A limit changes what you shoot. With 36 frames you can afford a few experiments. With 12 you start choosing. Film photographers say the cost of each exposure made them wait for the right moment, and a digital roll with a hard cap brings back a version of that.

The count also decides how your proof sheet reads. A sheet with 12 frames shows everything at a glance. A sheet with 36 gives you a run to edit. Read what is a contact sheet for how to work through one.

What happens when the roll ends in Proofsheet?

The roll finishes and develops at the time you set: when it ends, tomorrow at 09:00, on a day you pick or, with Pro, at a custom time. You can also tap Develop now at any moment. If you do that before shooting every frame, the unshot frames are lost, as they would be on real film.

Free users can have one active solo roll at a time. Pro allows up to five.

How many photos can a crew roll collect?

Each friend shoots their own roll, and the host collects the frames. The crew sheet holds up to 36 frames on the free plan and up to 300 with Pro or an event roll. For planning an event, multiply guests by frames each and compare the total with that cap. The article on how many disposable cameras for a wedding does the sums.

Is there a reason to want more frames?

Sometimes. Sports, children and street work benefit from a larger count because the best moment is hard to predict. For those, a camera that allows unlimited shots is the better tool. A limited roll is for moments you can see coming, or for the discipline of choosing.

How do I plan frames for a trip?

Count the days, then count the moments you already know you want. Say a long weekend with five anchor moments: arrival, a meal, a walk, an evening out and the goodbye. Multiply by two or three frames each and you land near 12 to 15. A 24-frame roll leaves a generous margin for surprises.

If you are covering a longer trip, load a fresh roll for each stretch instead of one big one. Proofsheet allows one active solo roll on the free plan and up to five with Pro, and each roll gets its own sheet at the end.

What if I run out of frames at the wrong moment?

This happens on film and it happens in an app. The fix is the same: hold back the last two or three frames on any outing. Spend them only when the best moment of the day shows up, and never on the first interesting thing you see.

A good habit is to glance at the counter at the halfway point of the outing. If it is already past half, slow down.

Where can I read more about frame sizes?

The numbers above come from the usual formats. If you want details of how they are made and where they came from, the articles on photographic film and what is 35mm film are good next steps.
