the subject. If the subject is overexposed (light), then you can rotate
the mode switch clockwise to reduce the light output of the flash
until the desired exposure is obtained. The AF35 provides five
reductions in power in one-half f-stop increments from the full
power setting, (Fig 4), for example, shows the mode switch set to
minus 1-1/2 f-stops.
When the AF35 is in any manual setting the Auto Exposure Selector
Dial setting has no effect on the flash output.
Switch the AF35 between Auto and Manual settings at any time.
AF35 Flash Ready Light
The Ikelite AF35 Flash features a
ready/confidence light at the rear of the flash	AUTO
that glows when the flash has recycled and is
ready to fire. When the recycle times range
between 10 and 15 seconds it is recommended
that fresh batteries be installed.
NOTE: The AF35 flash will most likely recycle
faster than the camera’s built-in flash. Since
the camera’s built-in flash is required to trigger	Ready
the AF35 flash, make sure the camera’s built-in	Light
flash has recycled and is ready to fire before
taking a picture.

Ready Light in Auto Mode

When the AF35 fires in the Auto Mode and enough light reaches the subject for proper exposure the ready light will glow green for about 2-3 seconds, then glow red. If the ready light does not glow green, but glows red immediately after taking a picture, not enough light reached the subject for proper exposure. Move closer to the subject and take another picture and check the ready light.

Setting the Auto Exposure Selector Dial continued Using Dual AF35 AutoFlashes

When using dual AF35 AutoFlashes, determine the optimum Auto Exposure Value for one AF35 Autoflash as described on page 6, then set the same Auto Exposure Value on the second AF35’s selector dial.

Setting the Auto Exposure Selector Dial
On the side of the Auto Sensor is the		Auto Exposure Selector Dial
Auto Exposure Selector Dial.			Indicator Mark
Different cameras may require
different exposure values. Once the
correct exposure value is determined
for a particular camera, no further
adjustments should be necessary to
obtain acceptable flash exposures of
varying subjects within normal shooting ranges.
To determine the camera’s optimum Exposure Value we recommend
the following procedure. This procedure can be done above water.
Make sure the camera’s battery is fully charged and the AF35 flash
has fresh batteries. Assemble the AF35 flash and camera housing with
the flash deflector installed on the housing. Make sure the camera’s
built-in flash is set to fire on every shot and is fully charged. Turn the
AF35 flash mode dial to AUTO. Set the Auto Exposure Selector Dial to
5 as shown above. Position the camera and flash approximately 1m (3
feet) from a colorful subject. Subject should not be allwhite or black.
Take a picture, review the picture, if the picture is overexposed (light),
turn the Auto Exposure Selector Dial down to 4, if the picture is
underexposed (dark) turn the Auto Exposure Selector Dial up to 6.
Repeat this procedure until the optimum exposure is obtained. Once
the optimum Auto Exposure Value has been determined for that
camera, use that value anytime that camera is used with the AF35 in
the Auto Mode. Repeat this procedure anytime a different camera is
used with the AF35 AutoFlash.
For advanced users, the Auto Exposure Selector Dial can be used for
exposure compensation while remaining in the automatic mode.
When the AF35 Autoflash is set in the Auto Mode the Auto Exposure
Selector Dial can be used to increase or decrease the flash intensity in
difficult lighting conditions.	6

Mounting Ikelite Housings to the Tray

Applies to Single or Dual Tray.

NOTE: The AF35 AutoFlash can ONLY be mounted to Ikelite Compact Digital housing models DC-100 and DC-200.

Turn the housing so the tray mounting inserts on the bottom of the housing are facing up. Place the tray across the bottom of the housing, align the two outer holes in the tray with the mountin g inserts in the bottom of the housing. Insert the two mounting b olts as shown below and tighten the bolts firmly to secure the tray to the housing.

AF35 Flash Diffuser

The flash diffuser adds 10° to the	Tab
angle-of-coverage of the flash. The	Push and
	Lift to Remove
diffuser is usually not required unless
a wide angle lens is being used. The
white diffuser features two
protruding tabs for use in installation	Holes for
and removal. The tabs on the diffuser	Lanyard
should be positioned away from the	Tab
flash.

Place the diffuser over the front of the flash. Spread the two tabs

apart, insert the diffuser into the recessed front, and then rotate the

diffuser until it locks into position.

To remove the diffuser, bend one tab out towards the edge while

lifting simultaneously.

A lanyard can be attached to the diffuser by threading it through the
