sea& Introduction of sea YS-D1 flashing light

multi-reference: features seen on the internet are equipped with sea&; SEA brand-new synchronous TTL system, named "DS-TTL II". YS-D1 provides reliable and stable automatic exposure for built-in flash and pre-flash of various digital cameras. In addition, YS-D1 is equipped with synchronous TTL mode and synchronous manual mode (11 levels). When a digital SLR camera is installed in the diving shell, traditional manual flashing photography and traditional TTL flashing photography (using YS converter) can be used. In clear water environment, two YS-D1 in DS-TTL II flash mode can provide perfect lighting effect. When you want to emphasize contrast, you can set the main light to use DS-TTL II mode and the auxiliary light to manual mode (level 11), which can provide flexible but unrestricted control. When the underwater visibility is poor, the two YS-D1 are set to manual mode, which may produce better images. YS-D1 is the most versatile underwater flashing light. The exposure compensation function of DS-TTL can be adjusted by rotating the brightness control rotation system in DS-TTL mode. YS-D1 only needs 4 AA batteries to supply power, and it can provide the maximum output with flashing light index of 32. YS-D1 balanced beam is suitable and powerful enough for professionals to use. Compared with YS-11α, YS-D1 has 25% more light output, 5g lighter weight (1.8 ounces) and 1% smaller volume. YS-D1 is not only suitable for wide-angle photography, but also an ideal choice for macro photography to control the brightness subtly. High flexibility, flash index can be reduced to 1. YS-D1 provides automatic and manual control to obtain more perfect exposure results. YS-D1 is the most versatile underwater flashing light. YS-D1 is the world's first synchronous TTL underwater flash with the control function of exposure compensation (EV). Synchronous TTL flash usually emits about the same amount of light as the camera's built-in flash. However, many TTL systems are unreliable. The DS-TTL exposure compensation function of YS-D1 allows users to adjust the brightness (-1.5EV, -1EV, -.7EV, -.3EV, EV, +.3 EV, +.7 EV+1 EV light, +1.5 EV) in TTL mode. Three-color LED indicator light for improving operation efficiency: red light is on to prepare for shooting. Confirmation light: the green light is on for two seconds to prepare for DS-TTL II shooting. Synchronous TTL mode light: When the underwater flashing light sets the synchronous TTL mode, the blue light lights up to prepare for synchronous shooting. Two attached soft masks are unnecessary for macro photography, so it is suggested that no additional soft masks are needed. When the flash output is strong or the flash output needs a relatively wide angle, it is suggested to add a soft mask 1. When using a wide-angle lens, it is suggested to add a soft mask 12. You can choose three different beam angles according to the photographer's requirements. The ergonomic design YS-D1 will automatically detect the synchronous line connection, and the synchronous switch system will no longer be applied. Simple control and setting make the operation easier. Turn or click the brightness control rotation system to help in setup and operation. The optional spherical base is matched with the common YS base, and the flashing light can only be lowered upwards. Users can also choose a spherical base, and the flashing light can be adjusted at a variety of angles to match the photography.
