[QUOTE="Fred Kingston_RIP, post: 433304, member: 10742"] No. The meter can't measure something that hasn't occurred. The meter (when the camera is in iTTL mode, will shut off the flash after it has received enough light. Things to remember about flash. All flash is at maximum power. Flash is controlled by "duration"... that's the time the flash is ON... Flash is controlled by controlling the duration or time... the electronics turn the flash ON, and then turns the flash OFF when the meter has measured enough light... IF you could watch the meter during a flash's very fast sequence, you would see it move from under-exposed to 0, and the back to under-exposed... Nikon's external flashes have the same sensing system in them... the flash turns on at full power, and measures the reflected light at the sensor, and shuts OFF the flash... [/QUOTE]
