"EV changes Connected to Flash power incremwnts ?"

Visit my Nikonians gallery.



I find this changes in the photographs that I have taken recently with D800. In flash photography when I dial in +3 EV the flash power shows +3. When I dial +3 ev along with +3 flash increment the resulting snaps details show +6 flash increment. Can someone explain this?

Thanks in advance

The EC on the camera applies to the entire exposure. The EC on the flash unit applies only to the flash. So if you set -1EV on the camera and +1EV on the flash, the ambient will be dark and the primary subject will be normally exposed (-1 + +1 = 0 EV).

In your case, if you do +3 on the camera and then +3 on the flash, you SHOULD get +6.

As Brian says, what you are seeing is what you would expect. Flash and exposure compensation are cumulative; I'm not sure how else it could work

Agreed. However (on the d600 at least) there is a menu option that allows you to separate the two. ie camera exp comp does not affect flash output - can come in handy depending on your shooting style / requirements. V handy if you want to underexpose a background by a stop or two to make a subject pop

I'm told that canon works differently. My impression is that the two EC settings are separate but not cumulative. Certainly I know that my Canon friend goes through a different algorithm for setting flash than I do. We normally think a lot alike so I'm sure that there's something different, although I certainly don't pretend to be a canon flash expert.

Thank you Brain for the information. Cumulative effect was not known to me I am happy it cleared by slight flash over exposure.
