Flowers - after the rain
I own the Nikon CLS - SU800 with 2 SB200's. General setup is mount the two flashes at 9:00 & 10:30 position on one side of the lens. The lenses are the Nikon VR105 and the Sigma 150 f/2.8 macro (older version). These shots hand held. Sometimes I will hold one of the flashes off to the side. Some of the bee macros (phase.com - search - boatner) I have mounted a flash on a stand/ off to the side with a RRS wedding bracket.
When the primary camera was the D200 - just owned the two SB200s and used a S800 to control the flash. Haven't tried bouncing yet - lot of macro insects that are too flighty.
Thanks for the comments!
