    In the normal range of daylight, I rarely use a meter with negative film. They are very useful in low light though.

    The real challenge is making the creative decision how to expose, which the meter won't help you with anyway.
    A meter may not help you, but it helps me a great deal in measuring brightness range and so on. I noticed (about 1975 or so) that my eyeballs aren't very good at any but comparative measurements, while film has a fixed and known sensitivity. I like to know what I have on the emulsion before I develop it. I don't believe in bracketing with six dollar sheets of film.

    +1, The human eyes are a very poor instrument for measuring light intensity because they automatically react and adjust to changes without the person being aware of it.

    But very good at judging contrast which is what we actually do when assessing lighting conditions. During daylight hours the sun as a light source is constant. The only thing which changes it is the amount of cloud diffusing it.

    Sunny 16 conditions can be judged purely on the shadow definition which is a function of cloud diffusion of sunlight.

    I'm with Steve.
    The sun is the sun. When we judge "by eye" we are not really judging by eye (which truly is a very poor instrument as it adapts brilliantly to different light conditions) but inferring from experience. The sun is always the same. The sun above a certain angle, without clouds, is always the same in most of the photographer inhabited world. Yes conditions might be tricky above the Arctic Circles but generally speaking in Rome or in Buenos Aires the sun shines the same.

    Sunny 11-ish here in Norway, and and I was surprised to find that it was sunny 22 in Eritrea whan I was there many years ago. But 2000 m altitude near equator IS different from sea level at 60 degrees north.

    At 60 degrees North you rarely see the sun at a height above 45° on the horizon which is the condition in the Sunny 16 rule properly enunciated. I guess the "Sunny 16 rule" is mostly not applicable at those latitudes. Height on sea level is probably not a factor.

    A program, Planetarium, in my Palm says that the Sun in Oslo at astronomical noon is 52° on the equinox. That's the maximum height the sun can reach in Oslo (noon of the equinox). So the rule can still apply in Oslo, but not very often... actually almost never!

    Here in SF Bay of California, sunny 16 is remarkably precise. I do often over-expose by one stop though.
