light, spot measurements

of speciﬁc subject areas. It

erate light (neon signs, etc.),

highly reﬂective surfaces

or translucent subjects

(stained glass, etc.).

Exposure Proﬁle Target II

to create camera exposure

proﬁles. One side consists

of a central 18% gray patch

that is surrounded by 25

patches arranged in 1/6th

stop values, while the other

side is 18% gray card for

digital camera white balanc-

ing and spot metering.

Exposure Proﬁle Target

This is more economical

test target used to create

camera exposure proﬁles.

One side is nine gray

patches including black and

white, and the other side is

an 18% gray card for digital

camera white balancing and

spot metering.

18% Gray Card

18% gray card with

cover folds and ﬁts in a shirt

pocket. It provides accurate

exposures regardless of re-

ﬂectance ratio of the subject

and surroundings.

Synchro Cord
