"Are the Exposure Compensation and Flash Compensation controls independant of each other?"

I've read that the D4 was the first body to separate these two, but I believe the 7100 post dates the D4.

To put the question another way, if I'm using flash in addition to natural light (as in a fill flash situation), can the two controls be used independently of one another?

I'm hoping some more knowledgeable Nikonian comes along. I think this is an interesting question.

I was just playing around with my daughter's D70, and I can report that in manual mode (manual shutter and aperture, that is) with TTL flash turned on, the EC effects the flash power. I took two consecutive shots of a dark subject. One at EC -5, one at EC +5. The +5 is visibly brighter.

Hi Jeff,

Is what you're seeing because of the flash power or because of the EC itself? I think a better test would be to set the EC to a specific value (e.g. -0.3) and try to change the flash compensation control and see how that affects the picture. I haven't tried it, but my impression is that they act separately, so you should also see a difference in the scenario I describe.

Regards,

Enrique

I assume it was because of the FC, but I'm really just guessing.

EC doesn't have any effect on shutter/aperture in manual mode, right?

Correct. It only affects what the metering reads, which in turn affects the TTL flash exposure on a body such as the D70.

You want to experiment with custom setting e4.

As an example in a bright backlit scene if I use the entire frame option and want to reduce the background brightness with -compensation, the background will be exposed correctly but the backlit object will be underexposed even if the flash comp is +.

If I use the background option only, the background and the object are properly exposed when main compensation is set to -.

Good catch, Len. I hadn't run across that setting.

Jon, I don't have a D4 but my Df and the D7100 appear to work like the D4. In the case of the D7100 the first setting using both EC and FC seem to work better for me when I use an external flash instead of the built in flash. FC has a range of +1/-3 where EC is +/- 5.

Yes, that's correct.

On the D7100, if you want to drop the ambient exposure but leave the flash exposure alone, you simply put in some negative exposure compensation (EC). Or if you want to adjust the flash exposure but leave the ambient alone, you just adjust the flash exposure compensation (FEC).

On the D7000, for example, it doesn't work that way. If you want to reduce the ambient exposure but leave the flash exposure alone, you have to put in the negative EC, then put in an equal amount of positive FEC.

I like how the D7000 handles but the way the D4 and D7100 would be simpler. I wish the my D800 had this split control. I use external flash for fully 1/2 my shot so controlling ambient/subjects ratios is a concern with very many shots.

Yes you can separate the flash compensation from the overall exposure compensation on a D7100. It's Custom Setting e4; set it to "Background only".

Note that this feature is not available on the D800, announced about the same time as the D4.
