Horizontal, vertical

Many years back, when cameras were a status symbol, we acquired one of the Hot-Shot cameras, in vogue at that point in time. It had to be loaded with the 24 exposure film cartridges that kind of looked like the old telephone receivers. Now, every now and then we got more than 24 exposures out of it, sometimes, upto to 30. That made us very happy, customer delight if you will.

However, I was amused that every film roll can give such variations in the number of exposures - I am sure that the manufacturing process was quite evolved. It was never less than 24, it was always more. Nonetheless, I never got the answer either, that sophisticated Japanese manufacturers cannot get the film length right and it is usually more than 24 - talk of Customer Delight.

Then, one fine day, it dawned. Vertical shots use lesser film. By the time you finish 24 exposures, you end up getting up a little extra. It was never about the film length at all. Not sure what the practical application of this post is, in an age of digital cameras...

Hi,

It doesn't really matter whether u shoot vertical or horizontal - it takes the same amount of film roll lenght. A vertical shot is the same as a horizontal shot for the camera - when u see it, you just tilt it by 90 degrees for your viewing convenience! Think about it!
Cheers

oh yes, thats true isnt it? then, is it the manufacturing process that makes it so?

Yes, if I were to take a guess, it would have to be the manufacturing process. And why would they (roll manufacturers) not be too bothered by it? My guess again, from an economics stadnpoint, is - it probably costs very little to leave some extra length than to develop the technology to precisely cut it. And for every additional film that gets shot and needs to be processed, the money flows back to the manufacturers as they are the ones supplying the equipment and consumables needed to process it! So, it is a nice clique - all manufacturers leave a bit extra as when all these extra snaps are processed, they more than get their return on investment.

I guess that is really the case. Leave 2 pics odd extra in a roll and if 12 people give a roll for D&P, you have a roll free. nice.
