Shooting in TTL mode
▪
Set main dial switch on the underwater strobe body to TTL mode. Please refer to concrete
strobe User’s Manual to choose
appropriate mode (Z330, Z-240, Retra Pro
set to “S-TTL”, YS-D1/D2 set to “DS-TTL”, YS-250/DS-161/DS160 set to “TTL”).
▪
Set another dial (+/-Ev correction) on the underwater
strobe body to “0 ev” position, as initial setting. Using Z-240/Z330
strobes
, pay attention: magnet must be in “Push” position, for fiber optical connection set second dial switch to “0ev”
(
position “12 o’clock”), for electric wire connection set to “ttl” mark as fixed position (“9 o’clock”). In case of optical TTL,
adjustment (+/-
) is available by the strobe dial “+/-Ev” and also by the camera wheel “flash exposure compensation”, the
final value is the sum of these two corrections. In case of electric wire TTL, adjustment (+/-) is unavailable by the strobe
dial, but available by the camera control wheel using
“flash exposure compensation”.
▪
Connect TTL-Converter Hot Shoe plug to the camera Hot Shoe socket. Switch ON the camera. TTL-Converter activates
automatically (switch ON) when user pushes camera Shutter Release Button for shooting or focusing. Device goes to
standby mode (switch OFF) also automatically few seconds later (according the camera command), or after disconnection
from camera Hot Shoe socket.
▪
Camera recognizes E-TTL device on the Hot Shoe socket and confirms compatibility by
the “Flash” symbol
on the
service screen.
Submenu “External Flash func. settings” becomes available in camera menu only in case of full
compatibility of camera and TTL-Converter.

During the initial test, dependently of concrete camera model, strobes condition etc., photographer should initially adjust
(+/-) correction to TTL Flash exposure control. (Flash Exposure Compensation). Pay attention on this.
Later, photographer should use necessary correction in wide range, according shooting conditions, if images are to bright
or too dark.
