I noticed you had increased the ISO from 640 to 800 and then the shutter speed from 1/2000 to 1/2500 and kept the aperture @ f/9.

You just pointed out that the exposure for the two images was identical: ISO 640 — 1/2000 sec. at f/9 equals ISO 800 — 1/2500 sec. at f/9. I was so busy trying to show everyone how smart I was that I screwed up 🙂

The higher shutter speed needed for flight imaging is one factor but also the Juvi has some brown “splotches” on its back whereas the adult body is all white therefore it requires less light for proper exposure.

The latter had been my intent 🙁

You commented that you pushed the shutter button during the action without taking extra time to get everything perfect.

That is correct.

At the exposure you used (being 1 stop under)

One stop under what? I did screw up — see my replies to Joel Eade above) but I do not think that I said “1 stop under.”

comparing with the image of the juvenile did you go to a higher shutter speed because of the flight action as opposed to the juvenile swimming?

Probably.

I do enjoy trying to nut out these exposure questions.

Do see what I wrote to Joel. It is hard to do when the guy asking the question screwed up 🙂

Best wishes for the Christmas season. Merry Christmas.
David.

Thanks and ditto, with love, artie
