Chapter 1 D-180 Features
D-180 Main Functions
The D-180 is a high performance, multi-function underwater auto-strobe, designed to be particularly useful with digital camera systems and including features such as advanced cancel circuitry and an integral underwater light. Depending on what camera system and master strobe the D-180 is used with, the useable D-180 functions will be different. Some functions are only useable in conjunction with certain camera and strobe systems.
The main functions are:
1)Flash Function (External Auto Strobe / External Auto Function)
When camera shutter is released the D-180 flashes in time with the camera and automatically adjusts flash output for correct exposure.
Using the D-180’s “External Auto Flash Exposure Adjustment” (hereafter, “External Auto”) control mode the D-180 itself automatically adjusts for correct flash output amount and “proper” exposure. It is not necessary to rely on the camera’s automatic flash adjustment control. Or use the Manual Mode 4 step flash output adjustment for manual strobe control.
2)Slave Strobe (External Auto Slave Strobe Function)
When connected to another (master) strobe, including internal strobes of digital cameras, the D-180 flashes at the same time as the master strobe.
Using the D-180’s “External Auto” control mode the D-180 itself automatically adjusts for correct flash output amount and “proper” exposure. It is not necessary to rely on the camera’s automatic flash adjustment control. Or use the Manual Mode 4 step flash output adjustment for manual strobe control.
3)Advanced Cancel Circuitry
For digital cameras which emit a “pre-flash”, compared to conventional strobes with simple pre-flash cancel circuits which cause the camera’s internal strobe to emit a full discharge on the second main flash, the D-180 Advanced Cancel Circuit effectively reduces the main flash output with the following benefits:
-Conserves the internal strobe’s condenser energy so the internal strobe’s recycle time is shortened, allowing quicker follow-up shots.
-Reduces energy consumption so more images can be taken per set of batteries.
4)“Clear Photo System” Compatible
“Clear Photo System” allows the external strobe (D-180) to be more effectively used
