If the lens has a hood attached or if you are too close to the subject, the bottom of the picture might look dark due to the obstructed flash. If you use a super telephoto lens or large-aperture lens and the bottom of the picture looks dark, using an external Speedlite (sold separately, p.193) is recommended. 189
