During night dives, if I am using the modleing light from one of my dual DS200 strobes, there is a bright circular hotspot. It only occurs on whichever side I have on for the modeling light, and is more prevalent against a light background. Is this the modeling light staying on and being bright enough to appear in the photo? I dont think it is a hotspot from strobe aiming, because it only happens on one side if only one modeling light is on.
