Not sure if it's the camera or something else. Notice, on the right side, the monolights and shutter curtain aren't synch'd: It's close... but no cigar. I was shooting w/ Canon 5D, f/5.6 @ 200, ISO 100, w/28-135mm Canon IS USM zoom. Off-camera monolights, radio triggered. The max synch speed on this camera is 200th of a sec. But, apparently, it wasn't synching. Not sure if it's an issue with the radio trigger, the camera itself, or maybe that synch speed is only guaranteed using Canon Speedlites? (Anyone? Anyone? Buehler? Anyone?)
Here's an example. I used an SN shot cuz those were the only ones that showed the white wall on the other side of that god-awful sculpture. The image is untouched except for size-reduction and the copyright.
