This was part of a flour shoot at a friend's studio. For the sand effect we mixed different types of flour for slightly different textures. We had everyone involved with the shoot bring a large bag of flour to keep costs down!
For the lighting, there were two LED light panels cross-lighting the background mixed with large softboxes to the left and right for key & fill. The goal was to use the continuous lights to capture some motion in the flour while using the strobes to freeze the model in place. This was more successful in the standing shots, but I liked the depth if this low one!
