I tried taking some night portraits with my new DSLR for the first time last night and had some trouble. I was using a 60D, 50mm f/1.4, 430EX II flash, and Rogue FlashBender. I hate noise so I never want to shoot higher than ISO 800 if possible.
First I tried Av mode; I set my aperture to 1.8 and ISO to 800 but the resulting shutter speed even with flash was way too long...sometimes it was giving me 2.5s, and so obviously my subjects were turning out blurry.
So then I tried Tv mode; I set my shutter to 1/30 and ISO to 800 and had a much better result, but the resulting aperture was always 1.4, which meant I couldn't focus on a group of people, for example.
I guess the obvious answer is that I need to shoot in Manual mode? Or am I missing something
