This year I was lucky enough to get picked to be on the Marathon Photos team to travel to the Xterra Festival in Rotorua. It is the largest offroad multi-sport event in New Zealand, and the largest Xterra event in the world.
My challenge was to get shots in the forest of runners. I brought my lighting set up and scouted on the day before. We found 2 spots that worked for me. Both were in a “S” bend in the trail that allowed for a view of the runners individually even though there were many at one time.
Here is the lighting diagram for this setup. I put the main light to the right on a light stand and with Pocket Wizard remote triggers. The rim light (often called a hair light) was directly behind on the left hand side of the track. I also placed a 3rd light in the bush that was intended to light up the punga fern in the background. A lot of the time this did not make a lot of difference to the image so I ended up adding it to the main light setup to give me more power.
In the second location, I did more of the same lighting except I had some sunlight coming through the trees adding to the shot. I still made sure to expose for the daylight outside of the forest, and used the flashes as the main light in the exposure.
