	speeds slower than 8s are
	processed to reduce noise.
	While photographs are being
		SHOOT
		CUSTOM
	processed, “l m” will blink
	in the shutter speed/aperture
On	displays for a period of time
	approximately equal to the
	current shutter speed. In

	rates will slow and the capacity of the memory buffer will
	drop. Photographs can not be taken until processing is
