If you open the lens one f/stop wider, what change should you make in the
shutter speed?  And why?

Okay, gang, let's give a quiz....
The new semester starts for me tomorrow at 7 p.m., and I am planning to
give a short, simple quiz - multiple choice - to get a sense of what my
students do and don't know about the basics of photography - mechanics,
not history or aesthetics.

I don't care if they've ever shot film, know anything about processing
or printing. What I want to know is what they know about using a camera
- digital or film.

I have plenty of questions, but I wonder what any of you would ask...

Thanks -
B. D.

P.S. I don't care if they know which version of the pre-asph 50
Summicron is considered the best by Erwin Puts, nor do I care, or could
I ask, if they know what a NOOKY is...:-)

BD, you've reminded me of something I've been wondering:

Why do folks equate filters on a film camera to in-camera processing in
a
digital camera?

It seems to me that with digital:
Light enters lens, hits sensor, software in the camera corrects color

How is that different from:
Light enters lens, hits film, film is scanned, software in computer (eg,

PS) corrects color

If a filter would help in the pre-light-hits-film phase, why wouldn't it

help in the pre-light-hits-sensor phase?

Inquiring minds want to know.
