I have another absurd question that seems common sense but need reassurance from some opinions, does shaking the film canister that has exposed film inside of the film canister which is also inside of the plastic opaque container have a potential of ruining your film? Thank you!

No - not unless you are so violent as to damage all that protective material.

Not a problem.
Here's an example of results from film that experienced a lot more shaking than that:

Speaking more generally. Film is usually quite robust. It is susceptible though to extreme heat and excess moisture - and radiation (like X-rays).

Typically today we call the casing whith a spool that holds the film cassette.
And the plastic container with plastic cap canister.

Can I ask, Randall, if there is a reason/rumour or whatever that was obtained from a source that has led you to believe that normal shaking of the kind you mention might lead to a worry of this kind given the kind of protection there is from a film cassette inside its canister

It is just that I think this is the first inquiry of this nature I have seen kind.

Thanks

I'm curious as to what you think will happen if you shake a fill cassette?

Moderate shake is ok but if you drop your canister your photos will be blured...
Specially on 120 film shot on Pentax 6x7... :blink:

Why shake the canister to see if there's exposed film in there? How would you know if it's exposed or unshot or shot and developed? Just take the cover off and look. :whistling:

But I like the idea of the latent image falling off the film.

Yes, if one shakes the film too hard or drops it from great heights the latent image will just slide off the film and leak out of the roll of film. I heard that it can happen to digital photographs too. That is why one should never drop a film or digital camera.

With digital, those 1 and 0 bits fall into the bit bucket, lost forever.

If you shake it too much it will build up pressure and the shots will ooze out of the top of the canister. This happens even when I don't shake it, the good shots get out and I'm stuck w/ the leftovers.

I have met a few people who thought shaking or dropping a roll of film would blur or otherwise mess-up the images. Obviously they don't know how film works, but I don't think that alone is where it comes from. I believe someone somewhere started that as a joke, which led people who don't know about it to ask. Asking is far better than assuming.

If I had a special "sarcasm alert" flag, I would attach it to a bunch of posts in this thread!
I like these questions from those who are new to film. They remind us about how much knowledge we tend to assume to be generally understood.

I have seen people make comments about the image falling off the film in the past and at the time they really appeared to believe it. Of course other people thought that was funny and make jokes about it.

That was a problem with early hard drives. As the drives spun, the centrifugal force caused the bits to slide out to the outer edges of the disk, and if you didn't run the right tool, disingenuously named "defragment", eventually the data would slip off the edge of the disk and get stuck on the inside of the housing.

Maybe someone dropped a glass plate. :smile:

Well, my comment for instance was not intended to ridicule the OP, instead I am thankful to him for inspiring me to that thought of mine, which I really like.


I see Apug as something of give and take. To me this is a perfect example.
