Canon EOS20DBODY Using the Built-inFlash

Using the Built-in Flash

E-TTL II autoﬂash obtains high-precision and consistent ﬂash shots.

Using the Built-in Flash in the Basic Zone

If necessary, the built-in ﬂash will pop-up automatically in low-light or backlit conditions (except in <3> <5> <7> modes).

Using the Built-in Flash in the Creative Zone

Regardless of the light level, you can press the <D> button to pop-up and ﬁre the built-in ﬂash whenever desired.

d: For fully automatic ﬂash photography. The shutter speed (1/ 60 sec. - 1/250 sec.) and aperture value are set automatically, just as in <1> (Full Auto) mode.

s: For when you want to set the shutter speed (30 sec. - 1/250 sec.). The camera then automatically sets the ﬂash aperture value to provide the proper exposure for your shutter speed.

f: For when you want to set the aperture value. The camera then automatically sets the shutter speed (30 sec. - 1/250 sec.) to provide the proper exposure for your aperture. Against dark backgrounds such as the night sky, slow-sync shooting will be set so that both the subject and background are exposed correctly. The main subject is exposed with the ﬂash, and the background is exposured with a slow shutter speed.

¡Because automatic slow-sync shooting uses a slow shutter speed, always use a tripod.

¡If you do not want a slow shutter speed to be set, set C.Fn-03 [Flash sync speed in Av mode] to [1: 1/250sec. (ﬁxed)]. (p.141)

a: You can set both the shutter speed (bulb or 30 sec. - 1/250 sec.) and aperture value. The main subject is exposed properly by the ﬂash. The background exposure varies depending on the shutter speed and aperture.

8 : The ﬂash result will be the same as the <d> mode.
