In this mode, the camera will automatically adjust the flash output level to achieve standard
exposure with Program AE, which automatically sets the shutter speed and aperture
according to the brightness of the subject.
• If the resulting picture is underexposed, increase the ISO speed.
In this mode, the camera will automatically adjust the flash output level to achieve standard
exposure for the automatically set aperture.
• If the aperture display blinks, it means that the background exposure will be underexposed
or overexposed. Adjust the shutter speed until the aperture display stops blinking.
Flash Shooting in Each Camera Mode
V: Program AE
X: Shutter Priority AE

In this mode, the camera will automatically adjust the flash output level to achieve standard
exposure for the set aperture.
If the background is dark, like a night scene, a slow sync speed will be used to obtain a
standard exposure of both the main subject and background. Standard exposure of the main
subject is obtained with the flash, while a standard exposure of the background is obtained
with a slow shutter speed.
• Since a slow shutter speed will be used for low-light scenes, using a tripod is
recommended.
• If the shutter speed display blinks, it means that the background exposure will be
underexposed or overexposed. Adjust the aperture until the shutter speed display stops
blinking.
Select this mode if you want to set both the shutter speed and aperture manually.
As the camera will automatically adjust the flash output level according to the aperture you
set, the exposure of the main subject will be standard. The exposure of the background is
obtained with the shutter speed and aperture combination you set.

To save battery power, power will be turned off automatically after 5 min. of idle use. To turn
on the power again, press and hold the Speedlite’s power button for at least 1 second.
* Canceling the auto power off function is possible. (p.14)
When you press the camera’s shutter button halfway, the flash may fire repeatedly. This is
the AF-assist beam function that facilitates autofocus for dark scenes. Its effective range is
approximately 2.8 m.
This function is available when using the Speedlite with an EOS camera that has an external
flash control function. Depending on the camera model, note that the firmware may need to
be updated.
During wireless flash shooting, the 90EX will not fire as AF-assist beam.

With multiple Canon Speedlites having the wireless flash feature, you can create various
lighting effects with the same ease as using normal E-TTL II/E-TTL autoflash.
The settings you input with the 90EX attached to the camera are also automatically
transmitted to the slave units which are controlled by the master unit via wireless. Therefore,
you need not operate the slave unit(s) at all during the shoot.
The basic wireless set-up is illustrated on the next page. All you need to do is set the master
unit to <a> to enable wireless E-TTL II autoflash (p.18).
You can use the menu to switch between normal flash shooting and wireless flash shooting.
During normal flash shooting, be sure to turn off the wireless setting to use the flash.
About Wireless Flash
Wireless Settings
During wireless flash shooting, the 90EX fires to control the slave flash but does not fire
as a flash.

In this shooting mode, all flash units except the 90EX fire with the same flash output, and E-
TTL II autoflash is used to obtain a standard exposure from the total flash output.
1 Check the communication channel.
You can change the transmission channel to avoid
interference with other wireless multiple Speedlite
systems being used. Set the same channel for both
the master unit and slave unit.
2 Position the camera and Speedlites.
Position the Speedlites within the range shown on
page 20.
3 Set the master unit’s flash mode to
<a>.
For shooting, <a> will also be set
automatically for the slave unit(s).

Position the slave unit using the mini stand supplied with the slave unit (the one with a
tripod screw hole).
For slave units with the horizontal bounce function, point the sensor of the slave unit
toward the master unit.
Indoors, the wireless signal can also bounce off the wall so there is more leeway in
positioning the slave unit(s).
If the sensor on the slave unit is not facing the master unit, the slave unit may not fire.
After positioning the slave unit(s), be sure to test the wireless flash operation before
shooting.
To avoid interference with the transmission, do not place any obstacles between the
master unit and slave unit.

Flash exposure compensation and other settings set with the master unit will also be
automatically set in the slave units. Thus, you need not operate the slave unit(s). Wireless
flash with the following settings can be done in the same way as with normal flash shooting.
· Flash exposure compensation · FE lock
· High-speed sync (FP flash) · Manual flash
Using Fully Automatic Wireless Flash
With FE lock, if even one Speedlite results in underexposure, the <Q> icon will blink. Increase
the ISO speed, open the aperture, or move the slave unit closer to the subject.

A and B to obtain the standard flash exposure of the subject, and slave group C to illuminate
the background to eliminate shadows.
1 Set the slave units.
See “Setting the Slave Units” on page 23 to set the
slave unit’s ID to <1>, <2>, or <3>.
For slave <3>, also set the flash exposure
compensation as necessary.
2 Set the master unit and shoot.
Follow “Setting the Master Unit Flash Ratio” on
page 23. In step 1, select <k>.

If you need more flash output or want to perform
advanced lighting, you can increase the number of
slave units. Set an additional slave unit to the firing
group (A, B or C) whose flash output you want to
increase. There is no restriction on the number of
units.
For example, if you set a firing group with three slave
units to <1>, the three units are controlled as a single
firing group A with a large flash output.
