Exam 6: Flash Photography

The use of multiple flash units to reduce glare or create more even lighting is accomplished with the:

Because the light created by a flash moves away from the flash source it appears to disappear; for instance, the light from a single flash illuminates a subject 20 feet away slightly, 10 feet adequately, and 5 feet too brightly. This is known as:

Electronic strobe flashes for camera were invented by Thomas Edison in 1803 in Harrisburg, Pennsylvania.

In painting with light, if the individual holding the strobe does not remain outside of the field of view of the camera, he or she will appear as a ghost-type image in the photograph.

The use of a material, such as a handkerchief or cheesecloth, to reduce the intensity of light and therefore require increased exposure is a process known as:

_________________ with light is a film camera technique that simulates multiple flash, but requires only one flash unit.

Guide numbers provided by manufacturers of flash units are often greatly inflated which mandates the units be tested carefully by the photographer before professional use.

Off camera flash techniques refer to:

The two types of flash used by photographers are:

While penlight batteries are the power source of choice for flash units for photography, the expensive nature of these batteries makes them nearly impossible for police departments to buy in large quantities.

Subjects with reflective physical properties such as glass, glossy painted surfaces, or finished wood may exhibit specular reflections when photographed known as:

The primary consideration when figuring exposure for flash is the distance of the subject from the flash.
