Hi guys, i want to know if there is a difference of  exposure between dslr, arri and red, film cameras, and film slr like nikon fm2, i mean is the amount of light needed is the same for all these systems and is just about the lens, or is it different.
thank you

There's no difference. ISO rating is a standard so 100ISO represents the same sensitivity to light whether digital or film.

I think Nossair might be asking about how much light is needed, not just what ISO means. o some cameras will need more or less depending on what ISO is acceptable to shoot on them.

It's should be the same, except, obviously each format has different DR. An image from a dslr might have clipped highlights vs on film most likely you won't have that issue. Same thing goes for shadow details. Same exposure on a format might end up with more information in the shadows.

Exactly. the cameras may all be "properly exposed" or have the same settings,  but the dynamic range will effect the perceived contrast, which will also effect whether the scene feels to dark, or too bright. For example, when I'm shooting on a DSLR I generally tend to under-expose just looking at the image, whereas when I'm on a raw camera or one with LOG-C I'll tend to over-expose even if both scenes have the same amount of light in them because to me it effects how I am looking at the image on the whole.
