There was no fill flash. It was taken at 1/1000th sec @ f/5.0, ISO 200, 70-200mm lens at 100mm, about 12:42 pm on a very bright day.
Then I speculate that the shadows were light-filled by the warm-toned gunflash, changing the lighting ration from 4:1 (normal noon sunlight) to near 2:1 lighting ratio. Excellent timing.
