Figure 8.2 Electronic flash can freeze almost any action.

Cost—Pro: continuous lighting. Incandescent, fluorescent, or LED lamps are generally much less expensive than electronic flash units, which can easily cost several hundred dollars. I’ve used everything from desktop high-intensity lamps to reflector flood lights for continuous illumination at very little cost. There are lamps made especially for photographic purposes, too. Maintenance is economical, too: many incandescent or fluorescents use bulbs that cost only a few dollars, and LED lamps are not only much less costly to operate, they are virtually immortal.

Cost—Con: electronic flash. Electronic flash units aren’t particularly cheap. The lowest-cost dedicated flash designed specifically for the Nikon digital cameras is about $150 (the SB-300), and it is probably not powerful enough for an advanced camera like the Z7. Such basic units are limited in features, and intended for those with entry-level cameras like the Nikon D3500. Plan on spending some money to get the features that a sophisticated electronic flash offers.

Flexibility—Pro: electronic flash. Electronic flash’s action-freezing power allows you to work without a tripod in the studio (and elsewhere), adding flexibility and speed when choosing angles and positions. Flash units can be easily filtered, and, because the filtration is placed over the light source rather than the lens, you don’t need to use high-quality filter material. For example, Roscoe or Lee lighting gels, which may be too flimsy to use in front of the lens, can be mounted or taped in front of your flash with ease.

Flexibility—Con: continuous lighting. Because incandescent and fluorescent lamps are not as bright as electronic flash, the slower shutter speeds required (see “Action stopping,” above) mean that you may have to use a tripod more often, especially when shooting portraits. The incandescent variety of continuous lighting gets hot, especially in the studio, and the side effects range from discomfort (for your human models) to disintegration (if you happen to be shooting perishable foods like ice cream). The heat also makes it more difficult to add filtration to incandescent sources. (It’s no wonder that LED illumination is rapidly becoming the go-to continuous light source for photography.)
