2.2 salamatilaa

Paina MODE -painiketta selataksesi käytettävissä olevia salamatiloja:

• TTL (Through-The-Lins) -tila: The flash output is automatically controlled by the camera's metering system for optimal exposure.
• M (manuaalinen) tila: Allows you to manually set the flash output from 1/128 to 1/1 power. Use the dial to adjust the power level.
• MULTI (Stroboscopic) Mode: Fires a series of rapid flashes during a single exposure to capture multiple movements of a subject. You can set the flash frequency, number of flashes, and flash output.
• S1 (Slave 1) Mode: The flash fires in response to a single pre-flash from a master flash. Suitable for manual or TTL master flashes without pre-flash.
• S2 (Slave 2) Mode: The flash fires in response to the second flash from a master flash, ignoring the pre-flash. Suitable for master flashes with pre-flash.

The flash head can be rotated and tilted to bounce light off ceilings or walls for softer illumination.

• Vaakasuuntainen kierto: 0–270 astetta.

2.4 Using Diffusers

The kit includes soft and hard diffusers to soften the light output and reduce harsh shadows.
