Ttl Flash Mode; Manual Flash Mode; Autofocus Illumination; Color Temperature & Auto White Balance - Dörr Macro Flash DMF-15 Notice D'utilisation

Note: Your camera's stop down button allows checking the focus area before shooting, depending on the selected aperture.
The Macro Flash boasts of the following guide numbers:
• one side operation: guide no. 10,7
• both sides in operation: guide no. 15

3.4 TTL Flash Mode

The TTL flash mode is easy to handle and provides a high exposure precision. Moreover it has the following advantages:
• Camera settings and corrections are not required
• Lens extensions (e.g. with extension tubes) are automatically recognized
• Filter factors (e.g. for polarizing or neutral density filters) will be considered
• Automatic calculation of the variable aperture of zoom lenses
• The film speed in use /ISO no. will be considered and calculated correctly
• The usage of soft boxes and bouncers in case of indirect flash will be calculated correctly
• Only the required light for correct exposure is measured

3.5 Manual Flash Mode

Instead of using a TTL flash control, you can also adjust the flash power output manually using the manual
mode. The LED on the rear side of the main flash indicates the selected mode. The following power ratios
can be selected by pressing the mode button: M1/1 (full ratio) - M1/4 (1/4 of flash power) - M1/16 (1/16 of
flash power). If you wish to return to TTL mode, press the mode button again until the LED indicates TTL.

3.6 Autofocus Illumination

The DÖRR Macro TTL flash boasts of an assisting autofocus illumination. SLR camera require a certain minimum contrast for proper
distance setting. In case of inferior light conditions, the contrast of the object may be too small for autofocus. In this case DMF-15
macro flash can emit a contrast pattern which is activated by pressing slightly on the camera's shutter release button. The camera's
autofocus with its autofocus red light beam can now recognize structures of your object and calculates the distance even in darkest
environments fast and precisely.
3.7 Color Temperature & Auto White Balance
The DMF-15 Macro TTL flash achieves a color temperature of app. 5.500 K. The camera's white balance will be automatically set to this
color temperature. Mixed light can create tints. We therefore recommend to set your camera's white balance manually to 5.500 K or to
flash light symbol, depending on the camera model.
3.8 Automatic Power Saving
To conserve the batteries, the DÖRR DMF-15 Macro flash features an automatic power saving mode. This mode automatically activates
approx. 2 minutes after the flash has not been in use. To re-activate the flash, turn the power switch to OFF and then to ON or push
down slightly the camera´s shutter. The flash is now in stand-by mode again. Should you plan not to use the flash for a longer time
period, set the power switch to OFF .

3.9 Exposure Control Display

The incorporated exposure control of the DÖRR Macro TTL flash displays OK (glowing for 2 seconds) for correct exposure. If there is
no OK, the shot must be repeated with a smaller distance to the object or with different camera settings. The exposure control is only
activiated in TTL mode and if the flash is connected to a camera.

3.10 Flash Synchronization

Synchronization time refers to the shutter speeds which will allow flash photography. Special attention must be paid in the case of
short shutter speeds. Each camera model features a „shortest" synchronization - the so-called x-synchronization. Please review the
instruction manual of your camera. Do not use shutter speeds shorter than the camera's x-synchronization for flash photography in
order to avoid incorrect exposures. Using the DÖRR Macro TTL flash in TTL mode the x-synchronization of your camera will be set auto
matically.
3.11 Modeling Flash
A modeling flash function is available to help you to check for shadows, reflections and light balance on your object before taking the
picture. To use this function, simply press the "MODE" button for 2 seconds. The macro flash will fire a series of flashes to help you to
determine the result of macro shot.
