Trying out some stuff with my lovely model.
Watch at home. NSFW.... Depending on where you work.....
Shot on RED Epic, @ ISO2500, at F5.6 and lit with a single 40w incandescent bulb held above the lens.
One of the reasons the footage appears so grain free, is that the Wollensak lifts the black up so high, almost to 40% on the waveform, that even at low illumination, it is above the noise floor of the sensor. When you push the blacks back down, the image cleans up rather nicely.
