Modeling Flash - Canon Macro Twin Light MT-26EX-RT Instruction Manual

E-TTL II/E-TTL Autoflash by Shooting Mode

Modeling Flash

When the camera's depth-of-field preview button is pressed, the flash
fires continuously for approx. 1 sec. This feature is called "modeling
flash". This is effective for checking shadows cast on the subject and
the lighting balance. Modeling flash can be fired during radio
transmission wireless multiple flash shooting (p.58) or optical
transmission wireless multiple flash shooting (p.82) as well.
To avoid degrading and damaging the flash head due to overheating, do
not fire the modeling flash more than 20 times continuously. After firing it
20 times continuously, allow a rest time for at least 10 min.
During Live View shooting, firing modeling flash (by operating the
camera) is not possible.
Modeling flash (by operating the camera) is disabled when using the
flash unit with EOS M6, EOS M5, EOS M3, EOS M2, EOS M, EOS Elan
II/Elan II E/50/50E, EOS REBEL 2000/300, EOS REBEL G/500N, EOS
REBEL K2/3000V, EOS REBEL XS N/REBEL G II/3000N/66, EOS IX, or
EOS IX Lite/IX7. Set C.Fn-02 to 1 or 2 (p.101), and then fire modeling
flash using the test flash button. (When using the EOS M series cameras
listed above, the test flash button functions when the camera's metering
timer is not active.)
You can use the test flash button to fire the modeling flash (C.Fn-02, p.101).
Color Temperature Information Transmission
This function adjusts the white balance depending on the color
temperature of the flash light by transmitting the color temperature
information to the EOS DIGITAL camera when the flash fires. When you
set the camera's white balance to <Q>, <Qw>, or <Q>, the function
is enabled automatically.
Refer to the specifications in your camera's Instruction Manual to find
out if it is compatible with this function.
