Christopher Nisperos said he used all Dedolights. I love my dedolights. They are very small and the light can be controlled very precisely. But they are very expensive and the hardest type of spotlight. I never thought of using dedo as key light on female face without diffusion unless she got faultless skin.

BTW, the people in Studio Harcourt seem to use Desisti and Mole fresnels. Their works are amazing. They seem to like use double soft fills--two fresnels bouncing off two reflectors on both sides of the camera axis.
