They sure do, but there are some important differncies.

You still haven't said what they are, I don't think you know.

if you don't know I'm not listing them for you. We are also
talking about qwhich is best for teaching photography. Teaching
photography adn gettiogn a good picture aren't the same.

There are no differences,

I can tell the differnce you can't.


No I've vere said that. are you sugeswstin we don;t need a light
meter because we have a digital camera ?.

Well its obvious that you can get the exposure by trial and error.

with a DIGITAL cameras can be acheived by just loking at the LCD. Now
tell me how you can do this with a film camera looking through the
viewfinder.

THIS IS A DIFFERENCE


this can be achived and that you can do that trial and error there
and then with a decent digital camera. you will claim that that's
too easy which i will ignore.

Of course you'll ignore it, because it proves you're wrong. Try
adjusing the aperature and the exposure time on a SLR film camera and
see if teh viwfinder image changes in any way. THIS IS A DIFFERENCE

You can select the 'speed' aka ISO of the 'sensor' either increase it
or decrease it for any frame or picture.

Now coem on tell me how you do this with film in the camera what
button do you use to increase/decrease the films speed. THIS IS A
DIFFERENCE .

With a DIGITAL camera you can increase/decrease Ap Tv and ISO. With a
film camera you CAN NOT change the ISO unless you change film or
change the way you process it AFTER taking the picture. THIS IS A
DIFFERENCE

which means with film you have to THINK before you even put the film
in the camera, you don;t have the same thoughts choosing a memory
card do you. THIS IS A DIFFERENCE

With film you have to decide whether or not you're taking colour or
monochrome, or transparancies, although colour film can be converted
to monochrome it's a bit wasteful. No sucvh thing with digital
cameras is theres. THIS IS A DIFFERENCE







cause the f..king sun goes in or it gets dark or night
approaches. you know brightness changes throught they day. Your
LCD and eyes react to changing light levels differntly and to
colur differntly.

Your eyes do, the camera doesn't.

yes it does compared to your eyes. have you never heard of tungsten
film ? THIS IS A DIFFERENCE


can yuo tell me what AWB is and what other options there are on a
typical digital camera can you show me these option for film ? THIS
IS A DIFFERENCE


You can see what the changes mean on a digital camera after you
take a picture you can only guess with film until you have it
processed.

THIS IS A DIFFERENCE

Having such a long delay doesn't aid teaching so digital is best
there too.

No it doesn't as few even notice. A friend of mine spent quite a time
in a musuem takign videos all with a yellow orange cast he thought
there's was something wrong with his camera, of course he didn;t
realise this until he got home. Me I knew immediatly what the problem
was because I know about film and digital and the differencies
between them. I'd have set the white balance before I started
recording. He thought the scene looked OK no colour cast and digital
cameras arn;t effected by such things as colour temerature of teh
light source. THIS IS A DIFFERENCE.


Its not a difference as far as teaching photography.
You obviously need a special camera tailored to your idea of what to teach.

the same as on a film camera or are you proposing that only
manual lenses are allowed.

if you want to learn about lenses use a manual lens, just like
you would a car.

A manual lens and an auto iris lens produce the same images.

my lenes from my film cameras have aprature rings I can turn to stop
down the lens. They also have a DOF scale and an IR mark, even a
distance scale on some.

So do mine on my digital.

Only preview and metering differ and they differ the same for film
and digital.

I've never seen image stablisation on a lens designed for film
cameras.

One of the reasons why digitals work better.
You can turn it off on all of them.

See as far as teaching goes there are no differences between film and
digital unless you decide to use them.
