Watt ? Candle Power... ?

Ray;

Write a book. They are so much fun to do and so easy to write! (Yeah, sure!)

PE

It's sure to be a seminal work.

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 300 watt bulb at 3 ft.

[Steve Smith]

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

How many candle power do you think that is?

[Kirk Keyes]

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

OK, now what's that in metric?

[c6h6o3]

OK, now what's that in metric?

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.

Anyone know how to quantify 800fc/sec?

[SkipA]

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."
