The Sea & Sea YS-01 Dual Lighting Package comes with everything you need to use 2 YS-01 strobes with your digital camera. Using 2 strobes makes it easier to light large areas when using wide-angle lenses and allows creative use of light ratios when shooting macro, marine life, and divers. The Sea & Sea YS-01 strobe is designed to be compatible with most cameras with a built-in flash. The automatic pre-flash function will adjust for most digital or film cameras.
The Sea & Sea YS-01 is a compact slave strobe with a circular beam angle of 100 x 100° and a guide number of up to 20. It is the perfect strobe for small Point & Shoot cameras or DSLRs. The DS-TTL (Digital Slave TTL) feature gives you automatic exposure control when shooting in slave mode. It is best to connect the strobe to the housing with the included fiber optic cables. For finer lighting control it is best to shoot in manual mode. This is easy since the YS-01 has a ten-level power dial located on the back of the strobe.
The YS-01 is powered by 4-AA batteries. You can get up to 330 flashes at full power with NiMH batteries. With NiMH batteries you will get a blazing fast 1.9 second recycle time, so you will not miss all the action on the reef. The YS-01 has a bright 1W LED target light that is bright enough to use as a dive light on night dives.
An external flash is your most important accessory. The ocean is one big, blue filter. As you descend, the reds and oranges quickly become muted shades of blue and gray. Using a color corrected strobe light will bring back your subject's natural color.
The included Sea & Sea Sea Arm VII Compact is constructed of fiberglass-reinforced plastic resin offering a lightweight yet strong arm. With the included camera base, head adapter, double ball section medium, and 2 ball clamps this is a versatile arm for all your lighting needs. An additional arm is included, so you can mount both strobes.
To complete the package the 2 Sea & Sea Strobe Mask Sets and 2 Fiber Optic Cables are included. The Strobe Mask Set is used to attach the Fiber Optic Cable to underwater housings that don't have fiber optic cable ports. The mask blocks the on-camera flash from exposing your subject, preventing back-scatter. The grommet allows the cable to be attached in front of the on-camera flash so the light will trigger your external YS-01 strobes.
