Out of curiosity, you mention that in Manual Mode on your D610, all EC does is change the exposure bar indication but are you referring to it being used with or without flash?

For info the D800 in Manual Mode works as follows;
a) With no flash, entering EC just changes the exposure bar indication.
b) With iTTL flash, entering EC changes the exposure bar indication and applies FEC.

I always wondered what the reason is for that behaviour of the exposure bar indication. Is it just a visible effect or has the offset for the calculations changed?

Grahame I was just referring to non-flash mode.

On my D610, there is a Custom Setting e4 called "Exposure Compensation for Flash". This gives a choice of "Entire Frame" or "Background Only". The effect of this setting is as follows

A. Shutter Priority

With "Entire Frame" selected, EC (which changes the Aperture) affects both the background exposure (ambient light) and the subject exposure (Flash light). With "Background only" selected, EC only affects the background exposure.

B. Aperture Prioity

The setting doesn't really have any effect because in this mode, shutter speed is varied with EC and provided that the shutter speed remains below the flash sync speed, it wont affect the flash exposure.

According to the manuals, the D810 also has this Custom Setting but the D800 doesn't.:(

PS: In Manual Mode, all EC does is change the exposure bar indication.

Just a thought.
In shutter priority the aperture will be the variable to be changed with EC. To change background only with a smaller aperture would mean that the flash output has to be increased to retain the same foreground.

George I think the idea is that by changing the exposure bar indication, it sort of encourages you to change one of the exposure settings until the bar looks good. In doing so, you get the modified exposure you were after.

Yes I think that would be so George.
