It looks like your shutter speed is too fast to sync with the flash units. Check your camera sync speed and make sure the shutter is set at a speed slower than sync speed. Jeff

Ditto. Your shutter speed is too fast. I shoot Nikon and 1/250 is the fastest speed I can shoot without this happening.

Hi Ron, The strobe has a very short duration, on the order of 1/1000 of a second. So if the shutter is only partially open you get only part of a picture. The strobe is not on for the entire time the shutter is moving, and the shutter does move. The highest speed you can use is called your sync speed, but you can also use any longer speed. You can get a lot more information about sync at this link: www.siskinphoto.com/magazine/zpdf/sync.pdf. Thanks, John Siskin

Thank you all for taking the time to respond. You have set my mind at ease regarding this being a camera issue. Unfortunately, I can not do another test run for a few more days because I've been traveling for work. I'll post the results after my next attempt. Again, I greatly appreciate you all taking the time to respond. Ron

Hi Ron, In trying to help myself understand this very thing, I came across this video on youtube which I found to be the clearest explanation that made it 'click' :) for me: here is the link: http://www.youtube.com/watch?v=Xnn5nzPvoIM if that does not work type in "digital photography 1 on 1" at youtube.com and it is the first video in the series (it says - Mark explains how the shutter works) I'm sure this will clear things up for you.

Hi Ron With the Canon cameras, at least some, when using a non Canon flash attatchment a different setting is needed for the flash. There may even be a different shutter speed for studio lights. READ the manual. On these the only thing you need to adjust is the shutter speed. Probably 1/125 second will do the job. Make sure the camera is set on the proper flash setting also. Lynn

Different camera models, even from the same manufacturer, have different sync speeds. So it is necessary to check what the sync speed for your camera model is. You can find this out in the instructions. You will be able to sync with strobes at any speed longer than the sync speed. Thanks, John Siskin

Thank you all very much for the feedback. I was able to confirm with an Alien Bees representative that the max shutter speed for my 40d would be 1/250th. Had I read the manual provided with my camera I would have seen this in the section regarding flash.
