[Light Currents]

Can anybody give advice about shooting nude outdoors? I would like to create the shadows for depth and mood that were exampled here, but I know outdoor lighting is harsher. It has to be outdoors because I've been playing around with infrared and need that sunlight, and would like to see what can be done with infrared. I have a number of flashes to use and off-camera triggers, stands, etc. I think I would like to fill with a single flash. Any advice about outdoor techniques would be appreciated. Links, etc. Thanks.
