I shot this with a Speedo 2400 series pack and two umbrellas set close together and rained down on my standing subject. I shot from a long distance at 180mm to keep the background narrow to make sure the bank windows behind would not register,and so my backdrop would be very dark at ISO 160 and 1/250 on the daylight, and with the lens stopped down to f/8 I had 800 watt seconds sent thru each umbrella but with the variator switch down four or five clicks toward the low end. At ISO 160 the original file of this had just stupendous information. Under this amount of light at this ISO, the original D2x files are really spectacular.
