The guy surfing in a hat gets my vote for sheer sartorial chutzpah.
Originally posted by voles Going back to your excellent introduction to the 'Sunny 16' rule: given that a camera body has a minimum shutter speed, (1/4000 in the case of the K10D) then there must also be a maximum aperture that can be used in the conditions you describe?
That's a good question. I'll have to consult my hi-tec exposure reciprocity calculator.

Yep, the Sunny 16 that I personally use would max out at f/2.0 at 1/4000 at ISO 100 in direct sunlight. Beyond that, I would know that the brightest parts of any clouds in the shot would be blown. But if it was a shot where blowing out clouds wasn't an issue, then f/1.4 at 1/4000 would probably work fine. I suppose f/2.0 at 1/4000 might become an issue for the razor thin depth of field types, who want to shoot portraits in full daylight where only the tip of one eyelash is actually in focus. But that's not an approach that I can imagine myself ever using. The present day obsession with thin depth of field in portraits is mostly about showing off that you can afford to spend thousands on a full frame DSLR with a very fast lens.
