TTL Flash Control | Kodak DCS Pro SLR/n instruction

Flash Photography

D-TTL Flash Control	The type of D-TTL flash control varies with the type of lens in use:

	Lens	Flash control for built-in Speedlight


	Type G or	3D Multi-Sensor Balanced Fill-Flash for Digital SLR:
	D CPU lens	Based on information from the matrix metering system, flash
		output is adjusted to provide balance between the main
		subject and ambient background lighting. The Speedlight
		emits a series of nearly invisible pre-flashes (monitor
		pre-flashes) immediately before the main flash. Pre-flashes
		reflected from objects in all areas of the frame are picked up
		by the camera’s through-the-lens (TTL) multi-sensor and
		analyzed in combination with data on the current sensitivity
		(ISO equivalency) setting, aperture, lens focal length,
		exposure compensation, and distance information provided
		by the lens. The results of this analysis are used to balance
		flash output with natural light. 3D multi-sensor balanced
		fill-flash for digital SLR is not available in Manual Exposure
		mode or when you use Spot Metering.

	Other CPU	Multi-Sensor Balanced Fill-Flash for Digital SLR: As
	lens	above, except that distance information is not included in
		regulating flash output. Not available in Manual Exposure
		mode or when you use Spot Metering.

	All types	Standard TTL Flash for Digital SLR: Flash output is
		adjusted to ensure that the main subject is correctly exposed,
		without taking the background into account. It is
		recommended for shots in which the main subject is
		emphasized at the expense of background details, or when
		exposure compensation is used. Standard TTL flash for
		digital SLR is activated automatically when:
		• Built-in Speedlight: the function dial is set to M
		(Manual Exposure mode) or Spot Metering is selected
		• Optional Speedlight: Spot Metering is selected
