Jack, Manual control of shutter does not work right in dynamic configuration. For the Sony Firewire cameras that you have on Marvin, the manual slider in the gui goes from 0 to 1. Auto shows (for my lighting) a number of 0.006. However, I was noticing that no calues between 0 and 16 were making a difference. Running, Coriander, I see that I can go from 3 to 1150 on the slider which equate to a shutter speed of 0.00001 to 16.0 seconds. So, the values you send to set the shutter are not floats in seconds, but integers (0-16; should be 3-1150 for my camera).
