The formula is: f/stop = sqrt (2) ^ stop number Or alternatively: f/stop = sqrt (2 ^ stop number) Where: f/1.0 = stop number 0, increasing thereafter by whole stops If f/1.8 is assumed to really be f/1.800000000 (unlikely), then it lies very close to 1+7/10 of a stop above f/1.0: f/stop =...

Do you recall the classroom lesson where the teacher asks her students "Where does your dinner come from?" And the young city child answers "The grocery store." Then the rural farm child quietly raises his hand and says "No, there's a little bit more to it than that..." This, I think...

Then perhaps we have inadvertently stumbled upon some common ground, as my use of the term "evolve" is as a synonym for "change". I assume no qualitative direction in that change. The change is objective. The quality of that change is subjective. I am concerned here with the former, not the...

Not talking about incremental technological evolution. Talking about incremental intellectual evolution. Which directly impacts progressive visual creativity. And which you appear to believe is impossible. Despite all of the obviously valid factual examples of it with which you have been...

At its most fundamental, yes it does. If one is an artist for whom an art sale in a competitive market means meat and potatoes on the table that evening, then you're darned right it's all about qualitative evolutionary change. That is Darwin's principle in spades. Reference The Daybooks...

That's how behavioral evolution works. That's how progress is made. That's how new replaces old. That's how better supplants worse. Excellence doesn't simply explode fully formed from a vacuum. Everybody stands on somebody's shoulders. Even if they don't realize it. Or want to admit it...

No, you should continue right ahead and go out and make your own unique best effort. Each and every successful member of previous photographic generations would tell you that, if they could. Don't let the grumpiness of others stop you. Their unhappiness is not your concern. Do it for the...

Absolutely correct... The so-called rules-don't-apply-to-me mentality is merely a false state of mind one chooses to believe for unrelated reasons. Perhaps for public image reasons. Or for self-image reasons. Or for self-validation. Or for self-therapy. Or for whatever. But it does not...

Is it possible the disconnect arose because they simply weren't speaking in your voice instead? Meaning, none of the works detained you because those works were communicating using a different set of rules than the set by which you were attempting their understanding? In other words, it was a...

PM sent with question regarding... 4. Mamiya TLR leather case - never used, in excellent shape. $20 Ken

Bethe, it's your photograph. No one else's. Title it whatever you like, whenever you like, as often as you like. If someone hassles you over the title upon entry to a venue, then that's a good indicator of a venue you may not wish to patronize any further, as they are obviously looking at all...

I am always amused by those who attempt mightily to wriggle out of the obvious. Everybody follows rules. Everybody. In photography and in life. From the moment we awaken each morning until the moment we fall asleep each evening. There is virtually no decision in life we make that does not...

As much as we'd all like to think we know the answer to that question for ourselves, or worse have convinced ourselves that we already do, only a prescient fate truly does. However, if we are talking probabilities instead of possibilities (or dreams, or delusions), then it's best for us all to...

"The most dramatic examples of savant syndrome occur in individuals who score very low on IQ tests, while demonstrating exceptional skills or brilliance in specific areas, such as rapid calculation, art, memory, or musical ability." — Savant Syndrome, online Wikipedia article :smile:
