 In the smaller photo, a directly aimed flash unit served as the main source of light. The skin color of the subject was faithfully reproduced, but the incandescent lamp was overexposed and casting a shadow in the background. In addition, the background was underexposed because the large workshop was not adequately illuminated by ambient light.
The main photo was achieved by bouncing the flash off the ceiling as an auxiliary light source. Using the incandescent lamp as the main source of light more naturally captured the intensity of the craftsman's expression. This is closer to how the scene appears to the naked eye. |

Photographers always have the choice of using a flash unit as the main or auxiliary light source. When a constant incandescent light source is available, it is often best to use the flash as an auxiliary light source in order to maintain a natural, warm atmosphere. The auxiliary flash can simply be bounced off a wall, ceiling or diffuser to soften the light and complement the lamp.
Determining the best flash exposure in such situations used to be difficult. But an EX Series Speedlite and EOS camera can automatically determine the ideal flash exposure level by metering the ambient light and preflash. This automatic ease frees photographers to concentrate on their art, rather than technicalities. |
