Upon reflection, I've got to say that Mr. bmattock has a very good point. His perspective differs from mine, and therefore I'm glad he shares his view. I don't entirely disagree with him. It feeds my own thoughts on what I do.
I feel that everyone can learn to use a camera without a meter.
I also feel that I rely too much on referring to parts lists and printed data at work. Given what I do and how long I've done it, I should be able to build a server entirely from scratch, regardless of model or vintage. But the fact is that as long as I have access to HP and IBM pats listings, I check first rather than just grabbing parts off a shelf and seeing if they work. But I know from experience that the best way to learn to build a server from scratch by memory is to just grab parts off the shelf.
The reason that works as a learning tool is because it's never a random grab. You are forced to choose based on what might work and why. Knowing the why behind it all makes future choices easier and more informed. You'll never consider the why if going by a manual.
Part of my insistence on shooting without a meter is to realize that part of the brain that never seems to come into play until forced. The part that trancends logical arguments and scientific proofs of inadequacy. The human brain is incredibly powerful and flexible. Before literacy was commonplace, the average person had to get by on a good memory alone. Imagine if no-one you knew could read or write. How many of us have jobs that would even be possible? Yet most of the world got by that way until the last hundred years. Purely on rote memory and clever figuring from other things they knew. My guess is they were much better at figuring than I am today.
Assuming flat out that the human brain cannot possibly match modern technology is tempting and believable. Yet obviously everything we assume to be better and more accurate than the human mind is quite obviously the product of such. Is it possible for a human to create somthing that surpasses our own ability? Honestly and absolutely?
I know a $5 calculator can do faster simple math than me on numbers under 8 digits, but I at least know how to add and multiply, etc. on numbers as large as you please. 250 digits multiplication? Not a problem, just give me some more paper please

I build heavy-duty computers, and let me tell you, it takes a human brain to get them to work at times. I'm not ignorant - I have a college education and I can tell you that machines as smart as humans can make them are still dumb. I know a handful of computer languages, and can say with authority that things don't happen electronically without the human mind.
There is not a single circuit capable of processing information faster or more accurately than the brain that designed it.
Those that we call geniuses for developing technology we can't live without created mere pale reflections of but one of their abilities. For all the Einsteins in history, there are hundreds if not thousands or millions that never had the opportunity to share or exercise their own gift.
If man can *create* a light meter, man does not *need* a light meter. Light meters are conveniences and sanity checks. They are not better than man or woman exercising their skills. That I truly believe.
Mr. bmattocks has demonstrated through his many posts here that what he shares on this forum deserves at least consideration. I don't feel compelled to agree entirely, but I have to say that he makes very good points that deserve appreciation. I use a meter when it's available. It informs my shooting without a meter. A meter is not necessary IMHO, but I will not argue the confidence it inspires. The fact that I have one occasionally reinforces what I've learned about shooting in daylight. I can't say it doesn't help because I use them. I'd actually have an argument if I didn't own a metered camera.
But the fact is that neither my Canonet, my Kiev 4, not the Leica CL are really useful after sunset if you need a meter. And since all meters are suspect due to age, battery life, or accuracy, one needs to always be second-guessing the meter. It only takes so long at the second-guessing before one puts it to the test - "Who am I to judge the meter?"
