Yes, and blindly following a meter is is poor substitute for experience.
Whomever said one should? I argue that the eye is a poor light measuring device. I have not said that one cannot get a reasonable exposure without a meter, or that a meter always renders the 'correct' exposure.
To paraphrase what someone else said, you don't meter with your eye, you judge exposure with your brain.
In the situation you mention, one is not judging exposure with one's brain, one is remembering similar situations and dredging up the memory of the exposure used in that situation, which is not at all the same.
One can also meter with a - gasp - meter and judge exposure with their brain. Which I would suggest is a reasonable way to apply years of experience and logic in many situations.
Correct exposure, after all, being that exposure that the photographer desires in a given situation. One controls focus - to achieve the effect one desires. Why would one not choose to control exposure for the same reason?
In countless familiar situations, many people can get exactly the right exposure 'by eye' = 'from experience'. Unfamiliar situations are another matter. But the longer you take pictures, and the more you practice, the more situations you can judge. Equally, the more you rely on a meter, the more that ability atrophies.
I disagree. They may get an acceptable exposure - and if it is the exposure they desire, then it is of course 'correct'. However, as I have said, the eyes lie and the brain swears to it - and most of us have had situations where we were certain we knew what the correct exposure ought to be, only to discover from our wonky exposures later that we were incorrect.
Relying on a meter is using a tool - like focusing, setting shutter speed, or selecting a film speed and emulsion. One bases one's choice on experience, but all are arrows in the quiver of the expert. I fail to grasp why a person would obsess over a lens design or a type of developer and then cast exposure to the Gods of personal experience.
That's why, as I said earlier, I'll usually set an exposure first, and check it with the meter afterwards.
I have not argued that one should do otherwise. I have not argued that anyone should be slavishly attached to a meter. I take issue with statements such as the one that kicked off this thread - "I don't need a meter."
If you, personally, can't judge exposures without a meter, or if you aren't happy doing so, fine. But your sweeping generalization needs a lot of qualifying.
Not only can I not judge exposure without a meter, neither can you or anyone else on the face of this planet.
That is far from a sweeping generalized statement. It is a fact.
You cannot stick your finger in a pot of water and tell me what the temperature is.
You cannot listen to a sound and tell me what the decibel level is.
You cannot taste a hot pepper and tell me what the Scoville rating for it is.
No one can. That's why we have measuring instruments.
What you CAN do - and what experts with experience have trained themselves to do, is exactly what you posited previously - to apply their remembrance of situations past to their current situation, and apply their memory of a correct exposure to it.
Will it be 'correct'? If they are correct in their recollection - yes. And quite often, the conditions are the same, or close enough that errors will be covered by the film or sensor latitude. That's exactly why 'Sunny-16' works.
As you also said - and I agree - if the conditions are unfamiliar, then this system does not work. The reason it does not work is because it is a 'memory game' - not a 'judging exposure' game. We remember what we knew was a correct exposure from times past and reapply it. No memory, no application. If we were in fact judging exposure with our eyes, we'd be able to do so in any given situation.
To conclude:
"Proper exposure" is the exposure one desires. It is an aspect of photography that is, to a large extent, under the control of the photographer if they wish to take control of it. Like focus, lens choice, focal length, shutter speed, aperture, framing and composition, and film choice, it is an aspect of creative control that we can either choose to control, or choose to let be. This is all for the photographer to decide - I can scarcely argue with their choices, since it is they who must decide what they wish to do.
However, judging exposure by eye is a guess, based on previous experience and similar (one hopes) conditions. It may well be a good guess - but it is certainly casting one's lot to the Imp of the Perverse as to whether or not it will work out as the photographer envisions.
I seldom see anyone advocating using a non-technical method to focus their camera - just give that lens a twirl and that will be good enough, eh? I seldom see anyone advocate just slamming any old film into their camera without any consideration for the effect it will give or its sensitivity to light or appropriateness for a given situation. We're all very particular about what we do in most cases. We even spend incredible amounts on special cleaning devices for our digital sensors to avoid the slightest damage.
But when it comes to exposure - well, that's a doddle. Just do whatever seems like it might have worked the last time.
It is naught but an additional element of creative control, which one may choose to seize and bend to one's advantage or not - and I would not gainsay anyone who decided not to. But to pretend that it actually is not a precise control that one can use creatively - because they can simply eyeball their exposure (they claim) seems a bit strange to me.
