Slowly but surely I am coming around to a deeper understanding.
You learn like I do. It's like watching water boil for others sometimes... There is a thread where Mark recommended a printing technique, and I didn't get it; 40 posts later, he repeated his original statement, and I finally got it. What a maroon I am.

"But I don't WANT to use f/16..."
That's the ticket - figure out how you can not use f/16. This thought process is what led me to high speed sync, and ultimately, using a neutral density filter for brightly lit, outdoor pictures, like this (no flash is on the left, flash w/ND on the lens is right):

ISO is in thirds
Well, technically, on that camera it is, but I believe that they are simulated equivalents; actual changes in sensitivity are at full stops, or 100, 200, 400, 800, 1600, and 3200. Isn't nice that ISO measurements are more intuitive? 400 is twice as sensitive to light as 200? Just remember that if your camera is set to 1/3 stop increments, then three clicks is always a one stop adjustment.

You most certainly aren't, but you've taken control of the situation, and asked the meaningful questions.
