Electronic Flash Basics

Until you delve into the situation deeply enough, it might appear that serious photographers have a love/hate relationship with electronic flash. You’ll often hear that flash photography is less natural looking, and that the built-in flash in most cameras should never be used as the primary source of illumination because it provides a harsh, garish look. Indeed, the most advanced “pro” cameras like the Nikon D2xs and D3 don’t have a built-in flash at all. Available (“continuous”) lighting is praised, and built-in flash photography seems to be roundly denounced.

In truth, however, the bias is against bad flash photography. Indeed, flash has become the studio light source of choice for pro photographers, because it’s more intense (and its intensity can be varied to order by the photographer), freezes action, frees you from using a tripod (unless you want to use one to lock down a composition), and has a snappy, consistent light quality that matches daylight. Even experienced photographers will cede that the tiny, optional, and not very powerful SB-N5 flash has some important uses as an adjunct to existing light, particularly to fill in dark shadows.
