I am just south of the tropic. Sunny 16 is right in summertime but probably
Sunny 11 in "winter". I would expect ISO's of about 1000 but am actually
getting up to twice that. I hate tripods.

Sunny 16 is rarely a correct exposure in any latitude where I’ve shot. Sunny
11 is much closer to the truth.

Yes, Jack, he is handsome & well caught.
I did some calcs. using the old Sunny 16 rule, @ 1/2000, f8, the ISO
should be 500. I see yours is 640 so the light was probably marginally
less than Bright Sun.
I've been trying the Sigma 170-500 with your 1/2000, f8 formula & find the
ISO's are going somewhat higher, even in what I would consider Bright Sun.
Next time I'm going to take my light meter along to get a cross check.
Perhaps the metering mode makes some difference too?
Also, I see you're using PSE10 so do you put the camera & lens models in
manually?

Visited the Sacramento National Refuge yesterday.
Really filling up now with the fall migration.
Absolutely hordes of noisy Snow Geese.
Attaching a handsome hawk. Perhaps a Red Shoulder.(?)
C&C? Thanks!
