Hi all, I am planning on using off camera flash with my Pentax 67 and buying a meter that can meter for flash.
Before I commit I want to check that I understand how to balance ambient and flash light to get a nicely exposed shot...
So say for example the shot is a person on a background outside.
I measure the ambient light and it is EV7 so at (for arguments sake) F4 the exposure for zone 5 (average) is 1/60
I then measure the flash on the subject. Say it measures EV9 so (again for arguments sake) at F4 the exposure for zone 5 (average) is 1/250 (2 stops brighter)
So to balance I would set my camera to 1/60 then set the aperture to F8 (2 stops less light than F4) to balance the flash. Or Shoot at 1/60, F5.6 to give me 1 stop of separation on my subject.
Is this correct!??
Thanks in advance wise men!
Also if you can recommend a cheap meter that will do this then fantastic!
