Question about lighting ratios
« on: February 19, 2013, 11:20:30 PM »
I have two strobes set up, each angles 45 degrees horizontally from the subject. Assuming no ambient light, if I shoot one  at 1/4 power, and the second at 1/8, is that a 1:2 ratio?  I'm assuming it is.

If I shoot one strobe at 1/4 power, and the second at 1/16, is that a 1:3 ratio?

Sorry for the ignorance, I just wanted to make sure I understood that concept correctly. Thanks in advance for your help.
In landscape photography, when you shoot is more important than where.

Gear: Canon 5DmkII, 17-40mm f/4 L, 50mm f/1.4, 70-200mm f/4.

1/4 to 1/16 is 4:1 (not the OP's 3:1).
