SPEEDLIGHT DVD GLOSSARY

Ambient Light

The natural, available light in a scene. Also known as

existing light.

AF-Assist Illuminator

LED light on the camera that illuminates the subject,

making it possible to focus on the subject even in total

darkness.

Automatic Power Zoom

The zoom head is automatically adjusted according to the

focal length of the lens in use.

Backlighting

The light coming from behind the subject.

Bounce Lighting

Using the bounce feature on a Speedlight, light is

bounced off a reﬂector, ceiling or wall to soften or diffuse

the light's intensity.

Chiaroscuro

Italian for light-dark, a term in art and photography

for a contrast between light and dark.

CLS

Creative Lighting System – Nikon's Speedlight system.

Feathering

Pan or tilting the light so that its dim edge is used to light

the subject.

Flash Output Level Compensation

Flash compensation used to increase or decrease the

output power of a Nikon Speedlight unit.

Fill-Flash

A technique to brighten dark shadow areas, often used

when the subject is located in the dark shadow.

Fill Light

A light that supplements the key light without changing

its character, used to lighten or open shadows within a

scene.

Front Lighting

Light coming from the direction of the camera toward

the subject.

FP Auto High-Speed Sync

Auto high-speed ﬂash synchronization enables CLS-

compatible cameras and Speedlights to sync at the

camera's highest possible shutter speed. This technique

minimizes depth of ﬁeld and freezes high-speed subjects.

Flash Synchronization

A means by which a Speedlight is ﬁred at precisely the

moment when the camera's shutter is at its peak opening.

Also referred to as ﬂash sync.

Front Curtain Sync

Also referred to as Normal sync, the ﬂash ﬁres

immediately after the front curtain opens completely.

FV Flash Value Lock

Locks in the appropriate ﬂash exposure for the main

subject, which remains locked whether the aperture,

composition or lens zoom position is changed.

Guide Number (Flash)

Guide numbers proclaim the light output of electronic

ﬂash units. The guide number divided by subject distance

represents the theoretical f-stop for an exposure.

i-TTL Metering

Nikon's Intelligent Through-The-Lens (TTL) ﬂash metering

using monitor pre-ﬂashes for unprecedented levels of

precision and performance.

Key Light

Also called "main" light is the principal source of light on

a subject or a scene.

Master Speedlight Unit

CLS-compatible Speedlight unit, built-in ﬂash or wireless

device (SB-700, SB-900 or SU-800 Wireless Commander)

that works in the Commander mode to send monitor pre-

ﬂash and ﬁring signals to remote Speedlights

Monitor pre-ﬂash

A series of pre-ﬂash ﬁrings detected by the camera's TTL

multi-sensor, analyzed for brightness and contrast. Also

used to communicate output values to remote Speedlight

units in multiple wireless lighting.

Quick Wireless Mode

The ﬂash output level ratios of two remote ﬂash unit

groups (A and B) can be easily balanced in quick wireless

control mode.

Rear Curtain Sync

The ﬂash ﬁres just before the rear (second) curtain starts

to close for special effects photography where the blur

appears behind the subject.

Reﬂectors

Flat devices, typically white, silver, or gold, that redirect

light to soften or ﬁll in areas of a subject or scene.

Remote Speedlight Unit

CLS-compatible Speedlight that can be set to ﬁre as a

wireless remote unit.

Repeating Flash

The Speedlight delivers a stroboscopic effect, ﬁring the

ﬂash continuously at selected rates.

Side Lighting

Light shining on the subject from the side relative to the

camera, often casting long shadows.

Slow Sync Flash

The ﬂash is controlled at a slower shutter speed to obtain

the correct exposure for both the main subject and the

background in low light situations or at night.

TTL

Through the lens. Any metering system - ambient

exposure metering or ﬂash metering - which works

through the lens.
