12, 24, 36, 100 ???
George Darwent
Hey all,
Novice question here I know.
I want to buy heaps of film for the Australian F1 GP this year but I
know what 12 exp,
24 exp, and 36 exp are, but what are 100 ft and 120? How many photos do
you get on that?
Does it work in a normal 35 mm camera?
Is the quality of the film reduced?
How much more is it to get processed?
Will I have to get it processed specially?
Thanks,
George Darwent

Where did you see the 100 ft? It could mean bulk 35mm film in 100 foot rolls,
or it could be the ISO rating of the film stated in Feet, as opposed to meters.
ISO ratings are indicated as older ASA and also European DIN, so you will see
100/21 on Fujichrome RD. 100 foot rolls have to be loaded into the familiar
35mm cassettes we all know or can be loaded into big special purpose camera
magazines/backs designed for several hundred frames of shooting.
120 probably refers to 120 size roll film used by medium format cameras such as
6cm x 6cm, 6cm x 4.5cm, 6cm x 7cm, 6cm x 9cm and some panoramic cameras.
Does this answer your query?

Well, 100ft is usually bulk film. You need a bulk loader and empty
cassettes or a camera back that will accept this large roll of film.
(Olympus, I believe, used to sell a 250 frame back for the OM sewries).
Bulk loading is OK but you have to make the investment in the bulk loader
and the casstees which need relacing after a while. The big backs are not
as popular and you might not be able to find on for your camera. Then too,
processing 100 ft at a time is difficult, if not impossible. You also run
the risk of losing "the frame" when the film is cut to fit the processor.
120 is a film size/package. It is used in 6mmX6mm, 6mmX4.5mm, and 6mmX7mm
cameras to name a few applications. It is NOT 35mm.
Check around for prices and remember, many of us buy in large, by our
standards, quantities and refrigerate or freeze it for storage.
Enjoy the GP.....

100 foot 35mm film is "respooled" into standard 35mm cartridges (to save
money) in frame counts from 1 to about 40. One frame takes about 1.5
inches of film, plus leader and trailer for each loading. There have
been some cameras modified or fitted with rare accessories that will
take about 100' of film at once.
120 is a film size just like 35mm is (35mm is known as 135). It is
about twice as wide. It is not used in 35mm cameras but in medium
format like the Hasselblads and Mamiyas.

See above
> Is the quality of the film reduced?
No, if it is not packed too tight.

Self loaded cartridges cost the same as store bought to process.

No.

100ft is a bulk film that come as a roll of 100 ft in a plastic back.
You have to buy a bulk film loader and canisters then you have to roll the
film into canisters yourself. On average you can roll about 18-20 36
exposures rolls per 100ft (btw, you actually have to load about 40-42
exposures in order to get 36 exposure). 120 is for medium format cameras.
You can shoot anywhere betwwen 12- 18 depends on what kind of medium
format camera you have. 220 is also medium format film, it doubles the
120's length. They are different sizes(bigger than 35mm) and also they
don't use 35mm canisters. 120 and 220 are rolled up in papers.
If you want to buy heaps of film, just buy 36 exposures of what you like.
100 ft will come out a little cheaper, if you know what you are doing, but
I don't recomend them to a novice, as you can expose the entire 100 ft of
film by accident. Also, only professional films come in 100 ft.
> Does it work in a normal 35 mm camera?
100 ft works in normal 35mm camera, AFTER you load them into canisters.
You can shoot 100ft of film, continuesly, if you buy a sepcial bulk film
backs for certain cameras, which are expensive.
> Is the quality of the film reduced?
No, they are exactly the same film.
> How much more is it to get processed?
The same, as long as you've load them into canisters(let say you loaded
36 exposures, the store will charge you same price for the "noraml" 36
exposures film).
> Will I have to get it processed specially?
No, they are the same film, hence the same process.
