[QUOTE="Stoshowicz, post: 368048, member: 31397"] Yes , I'm aware that there are two curtains, whether they traverse in the same direction and then go the other way at some point or whether they always go in opposite directions I don't know.. but I do know that curtains obscure light and at higher shutter speeds over sync speed , the entire sensor is not exposed all at the same time , there is always a differential time element as to WHEN a particular bayer array begins its duration of exposure relative to other arrays on other parts of the sensor. What I've seen of mistimed flash exposures suggests that the exposure opening is a diagonal slot. [/QUOTE]
