[QUOTE="WayneF, post: 414231, member: 12496"] Flash Compensation does affect (only) the TTL flash intensity. However, Exposure Compensation affects both ambient and flash (and adds to the other flash compensation), but in camera Manual mode, it cannot change the ambient settings. Canon is not that way, but Nikon defines "exposure" as ambient plus flash. EC will affect the TTL flash (and the ambient meter). I use it indoors when I need more than the +1 EV that FC will do (and the ambient is dim). +1 FC and +2 EC is a total of +3 EV to the flash, and +2 EV to the ambient. I didn't understand about the background - ISO 400 1/250 f/4 without flash ought to be pretty black indoors, even in a fairly bright room. Nothing to see. Yes, the manual means the flash lights the near subject, but may not reach as far as the distant background (depends where it is of course). Sounds like it was bounce? And ISO 400 f/4 suggests bounce. Bounce does light up the background (a little less dependent on distance), part of the reason we use it, but that illumination is from flash. 1/30 should affect continuous ambient, but not the flash, so that would be puzzling. 1/30 second should make the ambient show up, not bright but very visible now at ISO 400 f/4, and probably quite orange (seen with no flash). The flash should not increase. I suggest you stand up something that will make visible shadows from the flash, and also stand something near the lamp so it also makes decently strong shadows. Examining the shadows (intensity and direction) in the picture should help identify which light is which? You might try the same thing direct flash instead of bounce, to recognize the bounce contribution to the background. [/QUOTE]
