Just got done doing a 4 hour shoot with a beautiful model from Colombia while on a gorgeous island (Key Biscayne) near Miami.
Lighting Setup: No reflectors or lights, just natural light. Trees behind her to really make the beautiful bokeh pop in the background. A few shots had some crazy lens flares which I kinda like.
Settings: I was shooting at the highest shutter speed 1/8000sec and needed to stop down my F2 lens in order to avoid overexposing the shot. Sometimes I think about going down to ISO 50 but that would get me less dynamic range.
Time of Day: 1pm, not to hot, there was a lot of wind that was blowing in her face and hair, which helped create some absolutely spectacular images.
