Pilot lamp / Video mode (Fusion)
The installed pilot lamp allows a better orientation during a night dive. Similarly this LED
illuminate the object for autofocus and the cameradisplay .
To start the pilot lamp push the pilot button on the rear of your flash.
Pro160
: to switch off the lamp push the button again.
Fusion
: to change from pilot to video mode, push the button again. the fusion changes
from approx. 20% to 100% lightning power .
During the video mode the flash function is not available, this feature allows you to use the
lamp also for photos with ambient light and lamp.
To change back in flash mode push the pilot button again.
automatic TTL mode on analogue cameras
The flash identifies in AUTO - mode the connected camera system automatically.
(Nikon, Canon, Pentax. analogue )
The ttl-sensor is mounted in the camera and gives a switch-off pulse to the flash if the
exposure is OK.
•
For the correctness of the exposure is now the camera responsible, as the
delivered light achievement is determined by the camera. Therefore
manipulations of the exposure can in this mode of operation only be made at
the camera.
As soon as the flash is connected with a analogical camera, the ready symbol in the
camera lights up after touching the trigger lightly.
Strongly reflecting objects as well as back light photographs nearly always lead to under
exposure in the TTL mode. Use for this cases the manual mode or correct the exposure
index adjuster of the camera in positives (+). Do not forget resetting after shooting.
The same problem you have when using extreme wide angle objectives, if relative small
object is in front of a dark background. The sensor recognizes in this case mainly the dark
background and turns-off the flashlight to late. Overexposures results.
operating range on TTL-mode
According to the selected aperture arises the operating range, which depends also on
the turbidity under water.
The best aperture in the different situations depends on the needed reach and the depth
of sharpness. With smaller becoming f number (larger opening) the depth sharpness
range is reduced. Use a small f-number, where the background is to be illustrated in a dif­
fuse way. for Macro shoots normally higher f-numbers were used.
For standard situations a midrange aperture, f.e. aperture 5,6 to 8 is recommended. The
operating range in this case is approx. 2 meters (6,5 feet) which might be sufficient for
most UW photographs.
