Synchro Cord
This is a five-meter (16.4 feet) long cord with three plugs.
An exposure meter, a camera and a flash can all be
connected at the same time without having to plug or
unplug the cord during shooting. Also, the connection
terminal (male) on the light meter side of the synchro cord
has a locking mechanism to ensure it remains connected to
the meter.
(1 male terminal on the light meter side, 1 male terminal
and 1 female terminal)
■
Standard Gray Card
This gray card has a reflection ratio of 18%. Shooting this
card enables you to check the standard measured values.
If this standard gray card is measured in advance using
the reflected light system of the light meter, you can obtain
the standard exposure value. (Size: 125mm x 123mm =
4.9" x 4.8" when in use, 72mm x 123mm = 2.8" x 4.8" when
folded)
■
Exposure Profile Target II
Simpler to use, this is the test target used to create camera
exposure profiles. One side consists of a central 18% gray
patch that is surrounded by 24 patches arranged in 1/6th
stop values that are successively brighter and darker,
while the other side is 18% gray card, so it can be used
to determine digital camera white balancing and spot
metering.
(Size: 350 mm × 210 mm = 13.8" x 8.3")
■
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.
(Size: 280 mm x 180 mm = 11" x 7.1")
