Settings Detail
TTL
Mode
The
TTL setting represents using the full power of i-TTL technology.
By leaving Mode set to TTL (as shown in Figure 1) on each
of the Built-in or Groups A or B, you derive maximum flexibility
and accuracy from all your flash units.
In
this mode the Comp setting (Figure 1) will display exposure
values from -3.0 EV to + 3.0 EV, a full 6-stop range of exposure
compensation for each Group of Speedlights. You can set the
compensation in 1/3 EV steps for very fine control. If you
change Comp to a “+” or “–“ setting, the LCD Control Panel
will show the flash compensation symbol.
AA Mode
I am only briefly touching on the AA mode, since that is an
older non-i-TTL technology included for those accustomed to
using the older technology. With the SB-800 it is used primarily
by cameras not compatible with the Creative Lighting System.
It is not available for the built-in pop-up Speedlight on
the D200, or for the SB-600. You can safely ignore the AA
mode, unless you want to experiment with it. It will not provide
as accurate a flash exposure as TTL mode though, since it
is not based on the amazing i-TTL technology.
M Mode
This
allows you to set eight different levels of flash output for
the pop-up flash or the Speedlights in Groups A or B. The
settings you can put in the Comp field are: 1/1, 1/2, 1/4,
1/8, 1/16, 1/32, 1/64, or 1/128. Many people are used to working
with flash units this way, so it seems more familiar. CLS
is willing to oblige those experienced in working manually.
-- Mode (Double-Dash Mode)
The
built-in pop-up Speedlight will not fire the main flash in
this mode. It will fire the monitor pre-flashes, since it
uses them to determine exposure, and communicate with the
external flash groups. Be sure you always raise the pop-up
flash in any of the Commander Modes, otherwise the flash Groups
will not receive a signal and won’t fire their flashes.
Special
Note: Since the pop-up’s monitor pre-flashes always fire,
be careful that they do not influence the lighting of your
image. Use a smaller aperture, or move the camera farther
away from your subject if the pre-flashes add unwanted light.
When
setting the Mode for Group A or B to Double-Dash mode, that
entire group will not fire any flash output. You can use this
mode to temporarily turn off one of the flash Groups for testing
purposes.
Setting
the Channel (CH) for Communication
Look
at Figure 2, or your D200’s Commander Mode screen and
you’ll notice that just below Group B you’ll see a Channel
3 CH selection. (Outlined in red in Figure 2) The number
“3” (factory default) is the communication channel your
D200 is expecting to use to talk to the external flash
Groups.

You
can select any number between 1 – 4. There are four channels
available, just in case you happen to be working in the vicinity
of another Nikonian who is also using Commander Mode. By using
separate channels you won't interfere with each other.
It
is important that you realize that all your external flashes
in all the Groups must be on the same channel. This involves
setting up your individual flash units to respond on a particular
channel. We’ll next examine how to do that for the SB-800
and SB-600 Speedlight units.
