In a thread here about backlit photos, the following comment was made, "Be warned that even after a shutter release you still have FV lock. To unlock FV just press the funciton
This was exactly my question when I logged in here, but I wonder if it is the whole story. What things, besides pressing the function button again, unlocks it? Anything? One "trick" I was thinking of using was to set FV lock using spot metering on my subject and then switching to matrix metering, or just set exposure lock on the background.
Good ideas or bad? (I'm lazy, so I ask, though I'll probably get around to trying it anyway, regardless of the answers I might get, but I'm always open to the suggestions of those more experienced!)

I just went through the CF menus and confirmed that FV lock can only be attained via the FUNC button. The AE-L/AF-L as the button states can only do those two type of locks.
It's been a while since I last did some back lit shots but with the flash on TTL-BL the camera does a pretty good job in matrix in respect with the background exposure. Try that and see what you get. Another option is to set ambient manually and let flash determine the correct exposure. Under such high contrast situations such as noon daylight, the exposure for ambient shouldn't vary that much. Some prefer to dial down 1 to 1 and 2/3 stops on the flash for less of that 'flash' look. The key here is experimentation and finding what suits your need.
