In this case does the on-camera flash have to fire to trigger the other flash. I've used my SB-800 as a Master flash and triggered another SB-800(my fathers) for some creative lighting. What if I want just 1 flash to go off (the off camera flash)? Is this possibly without the Pocket Wizards? Or a Flash cord?
Yes. You can control the output of the on camera master flash.
The advantage with the Creative Lighting System is that you can control the output of the off camera flash from you on camera master flash. The disadvantage is range and sensitivity to the ambient light level. If the ambient light is really bright, or if you get too far away from the remote flashes you can expect some mis-fires.
NOTE: This is all coming from memory so a trip to the user guide or 5-10 min playing around will help you figure it out.
Basically the master flash will allow you to control up to 3 groups of off camera flashes as well as the on camera master flash. Your off camera flash will be in one group and the on camera master will be a seperate one (the master flash is always at the top of the SB-800 LCD when it is in master/commander mode).
For each group you can determine the mode the group will use. Each mode has a different letter code:
--
Flash Not Used (if it is the master flash it will still fire other flashes)
iTTL
ITTL flash (camera decides amt of light output)
AA
Automatic (flash decides amt of light output)
M
Manual (you decide how much light should be output)
Manual control + pocket wizards is my prefered method (check out the strobist link referenced above for the reasons why).
So to summarize what you would do to set up a one light off camera flash:
- -Set your on camera SB-800 to commander mode
- -Set the SB-600 to group A
- -Set the commander flash mode to "--"
- -Set the group A mode to "M"
- -Adjust the flash output to 1/4 power and use that as a starting point. Adjust the flash output as needed (a flash meter is really handy here... but your histogram will get you there if you don't have one)
The best advise is to test and get really comfortable with the setup before it is time to shoot.
Hope this helps!
