Originally posted by Moropo the purpose of my question was to understand the rationale of why the camera is choosing such a high ISO number given that it knows it will be using flash
It is quite simple really: the camera is trying to balance ambient light with the output from the flash. However in your case the ambient light levels are extremely low, so the camera is using a High ISO. This is why I prefer to use manual exposure when I'm working with flash. You will never see a studio photographer using AUTO- settings with professional strobes in a studio. Flash is a controllable, reliable light source. So when working with flash, I set my camera in manual mode so can set my exposure
exactly how I want it.
