Thanks for the compliments. For the shot of Jayme kneeling in the water, here is the camera setting information. Good luck with your shoots.
Nikkor VR 70-200 f2.8 G with polarizing filter
Image was shot at a focal length of 105mm
Exposure Mode: Manual 1/160 sec at f3.2
ISO 200 - Exposure comp: +0.3
White Balance: Cloudy +1
Color Mode: SRGB
Tone Comp: Auto
Time of day: 7pm - 15 minutes before actual sunset
Type of day: Clear with almost no clouds (unfortunately)
Position: Model facing sun, camera about 12 feet from model with my back to sun
On the shots where I used my SB-80DX for fill flash, I set the flash on manual at 1/1 (full power) then walk toward the model (or backward) until the fill light looks correct (I don't shoot with a meter).
Here's an example of shooting with the sunset behind the model and the on-camera flash illuminating the model -- using the same settings as listed above, but with a Cloudy-3 white balance..
