Exposure Compensation; Rear-Curtain Synchronization; Modeling Flash - Sigma EM-140DG Bedienungsanleitung

EXPOSURE COMPENSATION

You can compensate the exposure by changing the flash power level.
Intentional exposure compensation of the EM-140 DG NA-iTTL flash's power level
Dedicated exclusively to Digital SLR Cameras, F6, F5, F4 series, F100,
F90/N90, F90X/N90S, F80/F80 series, F70D, U/F65/N65, F801S/N800S,
F801/N8008, F601M, F601/N6006 and Pronea 600i only.
Cameras with EV compensation capability allow you to make exposure
compensation on either the EM-140 DG NA-iTTL or the camera (or both).
If you use both controls, exposure is modified by the sum total of both
exposure compensation values, and will affect the background exposure.
If your camera is an F601 / N6006 series camera, set the exposure
compensation by operating the camera's synchronization mode.
It can be set at 1/3 stop increments from +1.0 stops to –3.0 stops.
1. Press the MODE button to select the TTL/BL (TTL) mode.
2. Press the SEL button to make the compensation amount indicator
3. Press the + button and - button to set the compensation amount.
4. Press the SEL button to make the compensation amount indicator

Intentional exposure compensation of the EM-140 DG NA-iTTL flash's power level and background
◆This function can be used except F3 series, FM10, New FM2 and FE10.
Use your camera's exposure compensation control button or dial to make exposure compensation to both
foreground and background. (Please refer to your camera's instruction)
Exposure compensation on the M mode
On the M mode, you can change the aperture value on the camera, or change the flash power level, after
setting the exposure compensation.

REAR-CURTAIN SYNCHRONIZATION

When you photograph a moving subject with slow synchronization, usually the furrow of the subject will be
exposed in front of the subject. The ordinary flash light will fire when the first shutter curtain is fully opened, thus
the subject will be exposed from the time flash is fired to the time the shutter is closed (This is front curtain
synchronization). When you use rear curtain synchronization, the flash will fire just before the rear curtain begins
to close, and the subject will be exposed by ambient light from the time the shutter opens until the flash fires. As
a result, the furrow of the subject will therefore be recorded behind the subject, creating a more natural effect.
It can be used with cameras providing rear-curtain sync. only.
You cannot set this function on the flashgun directly. For details please refer to your camera's instruction manual.
The LCD panel on the flash will indicate

MODELING FLASH

If you use the Modeling flash, you can check the lighting and shadow effects, before you take the picture.

2. Press the + button or - button several times to make the
3. Confirm that the flash is charged, then press the TEST button to fire.
MULTI FLASH MODE
While the shutter is open, the flash will fire repeatedly. By doing so a series of images of the subject will be exposed
in one frame. A dark background with a bright subject shows more effectively in this mode. It is possible to set the
firing frequency between 1Hz and 100Hz. Up to 90 flashes can be fired continuously. The maximum number of
flashes varies, depending on the flash guide number and firing frequency settings. (Please refer to table3 on the last
page).
