[QUOTE="WayneF, post: 200534, member: 12496"] Several Nikon (and Metz for Nikon) flashes have a menu to select TTL BL or TTL flash metering mode. Nikons manuals (SB-600 page 33, SB-700 page C-2, SB-800 page 37 , SB-900 page D2) say the modes do this:[INDENT] [B]TTL BL - Automatic Balanced Fill-Flash:[/B] The flash output level is automatically adjusted for a well-balanced exposure of the main subject and background. [B]TTL - Standard TTL flash:[/B] The main subject is correctly exposed regardless of the background brightness. This is useful when you want to highlight the main subject. [/INDENT] Basically, TTL BL metering mode reduces the flash level when there is bright ambient, to reduce overexposure due to both flash and ambient adding to be 2x desired exposure on the subject (called Balanced fill flash). Whereas, TTL mode ignores ambient (normally insignificant indoors), and the flash comes ahead full on regardless of any ambient. Some Nikon flash models (SB-700 and SB-400), and the camera internal flash, and the Nikon Commander, have no menu, and are simply always TTL BL mode (balanced flash). However, we really simply do not know which mode is used with third party flashes (non-Nikon brand), which is the question. The camera does this, but it can depend on the firmware in the flash in those cases. We don't know, but evidence is that some are one way, some the other. That is why I am requesting to receive sample flash pictures from those, with full Exif, so we can know.
