Forget disposible cameras

Also with a disposable camera the Aperture (how much light the lens can let into the camera) Is set at about F/6.3 that means that it lets in about 4-6x less light than a normal film compacts lens, that means that the camera needs 4-6x more light so the film has to be 4x-6x faster.

I'm not too sure that's right to be honest.

1 stop brighter than f/6.3 is f/4.5
2 stops is f/3.2
3 stops is f/2.2
And then you start getting into silly money for a lens, definitely not what you would get on a normal film compact.

Using the 1/3 stop f-number scale you could go from f/6.3 to f/4 or f/3.2 in 4-6 thirds of a stop. That sounds more likely.

I keep a disposable camera in the car- handy in case there's an accident. That's about the only use I have for them- my old SLR's do everything else, digital and film.
