So what is the advantage of RAW, and what is the equivalent in film.

It is very approximately the equivalent to going back to the negative and
printing it at a different exposure or with different colour-correction
filters so you map a different part of the wide exposure latitude of the
negative onto the more restricted latitude of the print. Many automatic
printmaking shops have their machine set to clip the brightest 5% of the
print (the darkest part of the neg) to white and the darkest 5% to black
(thus losing detail at those two extremes) because this produces more
contrasty, less muddy prints.

But yuo don;t do that sort of thing with film.
There's no such thing as RAW in the film world.

Because in the film world you have to make the choice of which film to
load. Digital enable you to choose that later (with RAW) or decide
in-camera from shot to shot (if JPEG only)





try expaining why you'd use jpeg to someone that has only used film.
Why do yuo want a lower quaility image i.e a jpeg when yuo can have maxium quality


Because RAW to JPEG is the equivalent of developing a film. Most people
only want a postcard size print from film, you wouldn't pay to have a
10x8 print of every shot.








a 1/3rd of a stop surely with digital this should be expressed as 0.33333
of a stop and what is a stop in digital terms ;-)

As with film photography,

NO, I said explain what a stop is in digital remmeber you haven't a film canera yuo are teaching with a digital camera.
So what is a stop and what does it mean.
Why call it a stop one have such strange stop numbers.......
why does f5.6 let in twice that of f8

inverse square law.
A stop is a stop, digital or analogue, It is the effect of the iris in
the lens
