I bought a new flash last week and started using it with my Nikon D40 yesterday. The flash is the yongnuo yn-560 ii.
I had a tough time to photoshoot. I was indoors and shooting on A mode.
Many times the shutter was slow (adapting to the lack of light) and it seemed to me it was assuming I was using no flash. The flash was lighting properly and perfectly synced, but the shutter was still slow so most of my pics were blur because of the motion.
Is there any way I have to set up my D40 so it knows there is a flash and shoots fast? I am trying to avoid using the S mode.
