It cannot be changed by any of the camera settings. The base ISO allows us to compare different camera models in a useful way in terms of their light sensitivity, should we even want to do that. ... In the case of film, the ISO number really does tell you the light sensitivity of the film in some standard way.

films cant change the iso , just the shutter speed , digitals can , electronicly , still knows the digital camera cant make as good a picture as a film does .

Yes, it's true, you can't change the ISO of a film but you can adjust the ISO setting of the camera. You just have to consider that though when you process the film so you can adjust developing times accordingly.

No, you can't change the ISO of a film per se. But you can over and underexpose and compensate when developing (it's called pulling and pushing). Using tripods is often called for in film photography. So for most things there is a solution.

You can't actually change the ISO sensitivities on photographic film, my friend, but film cameras DO allow you to change ISO settings. In effect, this means that you're either under- or over-exposing the film, so this would need to be taken into account during the development process. i.e. you need to inform whomever is carrying out your film processing what you've done or their machines will see that it's over- or under-exposed and try to 'put it right'.
