In some shooting conditions or camera settings, TTL system may be not effective or
out of working range.
This case
photographer should use
Manual mode
.
Shooting in Manual mode
▪
Underwater photographer can use 3 different methods for shooting in Manual mode:
-
Camera menu Manual mode
-
Underwater strobe Manual mode
-
TTL-Converter hardwire Manual mode
o
Camera menu controlled Manual Mode
(set by camera menu assigned command
– “WL”)
Switch TTL-converter to Manual mode by camera menu
(“WL” setting in menu).
Set underwater strobe to “S-TTL” mode on the dial switch on the strobe body, - to control light intensity
manually via camera scale.
Sony camera menu does not have any original command for switching to M mode. That is why the “
WL
” command
(On/Off) is assigned for this aim via TTL-
Converter firmware. “
WL
” command ON switches TTL-Converter to M mode
without Pre-flashes. This is preferable Manual mode for universal usage, easy switchable and controllable during the
diving.
Base
d on your camera firmware, if “
WL
” sign doesn’t show on the Flash Mode Menu, it can also be found on page 11 of
Camera Menu 1. When ON, it will override the flash mode setting menu and the TTL system will operate in Manual Mode only.
In this Manual Mode the
flash intensity manual adjustment
by camera menu
also becomes available
.
Pay attention,
underwater strobe must be in STTL mode for this function. Then, user can comfortably adjust flash intensity by camera wheel,
looking at the camera scale. Full scale range (-
3ev….+3ev) corresponds to flash intensities 1/64 …1/1.
Some manual underwater strobes (like MF-1) requires very strong optical signal for synchronization, this case necessary to
set maximum power by this scale (+3 ev):
