Canon EOS D30 - Manual (Page 89)

The EOS D30 can take easy, natural-looking flash pictures with correct
subject illumination using E-TTL autoflash (preflash evaluative metering in
memory) and either the camera’s built-in flash or any EOS-dedicated EX-
series Speedlite. The procedure is as easy as a normal AE shot.
This chapter describes how to take flash pictures with the built-in flash, with
the EOS-dedicated 550EX Speedlite, or other types of external flash.
