Fill-flash

A method of flash photography which combines flash illumina

tion and ambient light, but does not necessarily attempt to

balance the two types of illumination.

Flash synchronization

The timing of the flash so it fires coincident with the operation

of the camera’s shutter. There are two types of synchronization:

Normal Sync which fires the flash at the start of the exposure,

and Rear Sync which fires the flash at the end of the exposure.

f-number

Number which indicates brightness of film plane image. In-

creasing/decreasing f-number is opening/stopping down lens

aperture. The f-number series is equivalent to 1.4, 2, 2.8, 4, 5.6,

8,11,16, 22, 32, etc. Changing one step to the next larger

number (i.e., from f/11 to f/16) decreases image brightness by

1/2; moving to nearest lower number doubles the brightness.

Guide number

The number given to a flash bulb or electronic flash unit to

indicate its power. A guide number may be quoted in meters

or feet, and depends on the speed of the film being used.

Guide numbers quoted assuming a relatively efficient reflector

surrounds the flash source, e.g., an average-sized room.

ISO film speed

The international standard for representing film sensitivity

(speed with which it reacts to light). The higher the number, the

greater the sensitivity, and vice versa. A film speed of ISO 200

is twice as fast as ISO 100, and half the speed of ISO 400 film.
