I am fairly new to the creative lighting system and have figured out how to set my sb-600's to slave mode and the d700 as a commander with the built in flash but I am having an issue that probably easily solved but my brain is frazzled...
I want to use one sb600 in my lastolite ezybox and one as a fill light elsewhere. I want to use the strobes in manual mode but can't figure out how to adjust the power output on the individual units without changing the power of the whole system. Have I just been stupid and left it on TTL?
I will be using this for weddings in mostly low light situations... With gels occasionally too

Set the SB600s to different groups on the speedlights themselves - group a and group b. Set them to manual on the D700.
Then on the d700 you should be able to set their outputs to different levels. As long as they are both set the same channel they will both fire; the different groups will fire at whatever output rates you set them to... At least that is how I do it on my D200...

First you need to realize that AWS, Advance Wireless System, with Nikon's CLS Speedlights and cameras use IR, Infrared, light communication between the Master/Commander and Remotes. This light can be reflected or blocked. Reflected IR is not always a problem but blocking of the IR light will prevent control of the remote units.
Using a box or umbrella is more subject to blockage of light form your camera's pop-up light. Only experimentation will determine if this is a problem.
To change the power on remote Speedlights one can only change the power level of the group of Speedlights. To control 2 different Speedlights power level requires each Speedlight to be in a different Group. You then set the power for the Group through the camera's Flash control menu using the "Comp" field.

Hi, thanks for the info so far, I understand the infra-red could be an issue until I can afford the radio transmitters. But I think I can get around this.... With the placement of my lighting etc.
I didn't realise the two speed lights need to be set to two different groups which allows you to then set the exposure compensation, that's great to know. I wish there was an easier way to dial it in though... can't have it all I guess.
I have been trying to find this info out for a little while, should have come here first as always!

While setting each remote Speedlight to a seporate group gives you more control over the lighting, the remote Speedlights do not have to be set in different groups. You can set any number of Speedlights to each of the two or three remote groups depending on the Master Speedlight that you are using.

One you get used to changing the settings, it will be much easier. Good Luck and Enjoy your Nikons!

My apologies to all, I am repeating some of what has already been posted.
In my experience, all speedlights configured within a given remote group will fire at the power level/exposure compensation specified in the Commander Mode using the popup speedlight, or in an on-camera Master SB700/800/900/910 speedlight.
If you want different power level/exposure compensation for each of the two remote SB600s, they must be in different groups.
In Manual Mode, you can specify the exact power level desired for each remote group: M1/1, M1/2, M1/4 etc. All remote speedlights in each group will fire at this level.
In TTL Mode, you can specify the exposure compensation desired for each remote group + 3.0 to - 3.0. All remote speedlights in each group will fire at this exposure compensation level.
Nikon suggests no more than three speedlights in any remote group. I have successfully conducted night shoots with several more than that, but it takes careful placement of the remote speedlights relative to the on-camera Master/Commander.
As George mentioned, the Infrared (IR) CLS preflash signalling does not necessarily require line of sight alignment between the remote speedlights and the on-camera Master/Commander. In small to medium size rooms, the longer wavelength IR signals will bounce off floors, walls, and ceilings and find their way to the remotes. In very large rooms and outdoors, or outdoors, line of sight is more critical. I have had remote speedlights in large umbrellas fire around corners in separate rooms when doing interior photography. As George also mentioned, you will have to experiment.
Configuring remote speedlights in Commander Mode is a bit tedious. It gets easier when working with an on-camera speedlight in Master Mode.
Hope this helps a bit.
