FlyingPhotog, I've been playing around with your info and I have a few observations.
Now, obviously you probably don't want to be schlepping around with depth of field that will cover from your nose to Kansas, so all you have to do is work the reciprocal exposures down to the aperture you want:
1/125 @ f/16
1/250 @ f/13
1/500 @ f/11
1/1000 @ f/8
1/2000 @ f/5.6
1/4000 @ f/4
1/8000 @ f/2.8
You didn't really mean to put f/13 in there, did you?
Now THIS is good info. Very handy!
I find the tricky part to be deciding what's "full direct sun." I thought that's what I was out in today and found I was having to give anywhere from 1-2 stops more exposure than the "sunny 16 rule" would indicate. I finally realized that my perception of "full direct sun" was colored by not having actually seen full direct sun for a while! (Come on, Spring!) When I actually paid attention, I realized that, while it was sunny with distinct shadows, it was far from full sun. Then I checked the time; it was about 3:30, not between 10-2. So much to keep in mind. But I think still better than P mode.
Anyway, thanks again for the info.
