    Optional Accessories (Sold Separately) • Synchro Cord This is a five-meter long cord with three plugs. An exposure meter, a camera and a flash can all be connected at the same time without need to plug or unplug the cord during a shooting. Also, one of the terminals has a locking mechanism to ensure connection with a meter. Cord has two male connectors and one female one. The connector with the lock function is a male one. • 18% Standard Gray Card This is a gray card (125mm × 130mm = 4.3” x 4”) with 18% reflection ratio, and folds to 72mm x 125mm (=2.8” x 4.9”) to fit in a shirt pocket. Use this for proper reflected light measurements of mostly bright (white) or dark (black) subjects. • Exposure Profile Target II Simpler to use, this is the test target (350mm × 210mm = 13.8” × 8.3”) used 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 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.
