    It's sure to be a seminal work.
    I do use a digital device in my photographic pursuits when necessary.
    When someone rags on me for using film, I use a middle digit, upraised.

    Ray, to get back to your question of what people are using for AZO and Lodima, I use a 40 watt bulb in a metal reflector at 4 feet.

    I use a 9.4 × 10 to the power of 16 watt hydrogen powered lamp at a distance of about 92,957,130 miles.

    The Watt is an SI unit of measure (1 Joule / second) so all we have to do is convert statute miles to kilometers. So, he's using a 9.4 × 10 exp 16 watt lamp at a distance of 149,599,999.42272 kilometers.

    holmburgers, I presume you are referring to Kodak's instructions for cine film reversal? Kodak says 8600 lux-seconds in the tech sheet for TRI-X Reversal Film 7278. Kodak added a note that it is "~800-footcandle seconds. A 10-second exposure to a common 60-watt lamp at 12 to 18 inches."
