The wonderful thing about off-camera flash is that you do not have to be a slave to the ambient light. Photographers that shoot only available light portraits have limited options when it comes to the time of day where the light is perfect. Golden hour, when the sun is low and warm, is fleeting and if there are clouds, well, forget about it.
Open shade is the other go-to for available light photographers. The light is super soft– to the point of being flat and uninteresting. Sometimes I wonder if that is why so many photographers are relying on Lightroom plug-ins to make their portraits more visually interesting.
In this photo of Elaine, age 10, I wanted to shoot a simple location portrait that captured the spirit of who she is today. Elaine and her family met me in a local park and after a few group family portraits, I repositioned my main light, a Westcott Rapidbox 3-foot octabox. By moving it in close, just out of frame, camera left, gave me some beautiful soft (but not flat) light to work with.
The early evening ambient light was pretty flat. The air was filled with smoke from local wildfires. To create a golden hour look, I put a second strobe with a Profoto Magnum reflector and full CTO filter (color temp. orange) behind Elaine on camera right. Actually, I had her dad hold the Profoto B1 strobe on a light stand high and aimed down on the back of her head. The warm light brought out the texture and red in her hair. The background was grass and cattail reeds, which at /f2.8 on my 80-200mm lens (at 200mm) made for some nice creamy bokeh.
