    So until my poverty wizards arrive in the mail, a blazing 11 or so days from now, I need to figure out Nikon CLS.

    What is really confusing me is why does my onboard flash need to fire in Remote mode on my SB-800? I thought it used infrared in remote mode, not flash.

    The D90 manual says it is because it needs to fire "monitor pre-flashes."
    WAT?

    WHAT GIVES?

    I'm probably just an idiot, but whatever :D

    The pre flashes are used to meter, the system sends out one flash to check levels and then fires all the flashes together. The on board flash does not affect the exposure.

    I put my onboard flash or 800 if I get my hands on it, to commander mode. Then set the slaves manually. No preflash that way.

    But the flash does affect the exposure a little bit. It's probably like 1/128 power, but it still adds some amount of flash. I thought the Nikon CLS was completely Infrared?Plus why does my camera need to meter in M?

    Hopefully. I got the confirmation of shipping on Friday, so maybe by Wednesday?

    This is why I'm confused. I thought the CLS was based on infra red signals. The Onboard flash is set to -- and the flash is set to M in the commander mode screen. So Confused.

    The short answer is no, CLS is not completely infrared. You can use an SU-800 Remote Commander in place of your built in flash to use Infrared communication but otherwise in that configuration you will need the on-board flash to fire.

    As for output from the on board while in commander mode, I have played with it and the output is practically nonexistent from an exposure standpoint. I have many series of test shots where I was dialing up the exposure one step at a time, with and without the slaves active and on board never contributed to the scene that I could tell.

    Unless you want it to; either with Manual or TTL settings.

    So assuming no other device is invloved...... how do you suppose the flash will fire without a pre-flash?

    In the Commander mode menu with the Built-In flash set to (--) it does not contribute to the scene. However, if you're close up on your subject and particularly if it is a reflective surface, then yes, it will show. You could use tissue paper to diffuse if needed.

    It is IR based.

    Ok. I guess I'll just use it until my poverty wizards come and I'll hope they come asap.

    Wow, I actually found CLS *easier* to use than my Gadget infinity setup, becuase there was nothing to do on my end... just aim, compose, press the shutter, CLS did the rest for me and thats it... lol.

    Have you tried places like:

    The Jerry Blog!: Nikon CLS play time!

    The Jerry Blog!: Specific settings for various CLS Configurations

    The Jerry Blog!: 60 Second Strobist #1

    Nikon CLS Practical Guide: 1. Nikon Flash - Two Separate Metering Systems

    Strobist: New Nikon Video: 154 Minutes of CLS Goodness

    Strobist: Nikon CLS Tutorial Video

    There were about 15,700 hits for "Nikon CLS tutorials" on google, but these were the first few. Youtube had a couple hundred as well.

    BTW, I've mentioned it here at least 5-6 times that the GI triggers/receivers were also available from MPEX.com... faster shipping than from Hong Kong and a couple dollars cheaper. They are based out of Ohio... a little closer so shipping cost and time is lower as well. ;)

    are you using the poverty remotes to fire more then just the SB 800.. Personally The CLS system is really easy to use. its all built into the gear you already have you dont need to worry about the batteries, other then in the flash and camera my remotes just sit in my bag i have only found a few situation where i needed to use the them.. but i still use the cls to fire my sb900 and attach my trigger to the PC port of the Flash to fire the other lights.

    I need the wizards for a location where the flash won't see onboard flash, so I need them to trigger it.

    Thanks for the tutorials guys!

    I guess I'll pick up a copy of the official Nikon CLS video.

    If you're indoors, the chances are good that the pre-flash still fires the off camera flash within 20-30 feet. You don't necessarily need line-of-sight. Outdoors in bright light is a different kettle of fish.

    I've had my off-camera flashes fire from behind walls using the built-in to trigger. Of course, I try to position the receiver in the most opportune direction.
