Good morning everyone (at least it is where I am) :-)
My set up is a Samsung NX 11 using a hotshoe flash on TTL mode.
Most articles on flash photography I've read recommend adjusting shutter speed to adjust ambient light levels as doing so means that the flash output doesnt need to change. Fine, I think I understand the theory behind that and have successfully tried it a couple of times in camera manual mode (flash on TTL).
However my question is this....If I'm in aperture priority mode (and I shoot a lot in this mode) can I simply reduce the EV reading in the viewfinder to reduce ambient light as I assume that, for any given aperture, the shutter speed will increase?
