Shooting Tips

If the resulting picture is too dark.

In Creative Zone modes: a, f, sor d, get closer to the subject or increase the ISO speed. By increasing the ISO speed, you can extend the flash range.

In other shooting modes, get closer to the subject and take the picture again.

Using fill-in flash

To take pictures of backlit subjects, select [Evaluative] for [E-TTL II meter.] (p.220). Using the fill-in flash function, you can have the subject’s face appear brighter.

In bright light, decrease the ISO speed. (a, f, sor d mode)

If the exposure setting on the LCD monitor blinks, decrease the ISO speed.

Detach the lens hood and keep at least 1 meter/3.3 feet away from the subject.

If the lens has a hood attached or you are too close to the subject, the bottom of the picture may look dark due to the obstructed flash. For important shots, check the image on the LCD monitor to make sure the flash exposure looks natural (not dark at the bottom).

When using the Mount Adapter EF-EOS M, the light of the flash may be partially obstructed, casting a shadow on the bottom part of the picture.
