Yes, two different uses of your flash. The help with focusing that requires mounting the flash, being in AF-S mode and the flash head in the direct forward angle Either put the flash into Commander mode or simply 1/2 press the shutter release to activate AF and the AF assist light, lock focus and turn off the flash to take your shot normally using ambient light. That of scourse works best in a Trap Focus mode where you focus to a spot and when the subject moves into the focal plane, the shutter releases. You press the release the whole time. Set the Focus priority to "Focus Priority" which is probably already set to that mode. The IR assist light will allow accurate AF in total darkness.
The use of bounced flash to augment ambient light is a very good way to get the noise handled, decrease ISO get better color but does involve the flash going off. Try some experiments. Go to a rehearsal and bounce flash a couple times without teling dancers that you will be doing it. Ask them afterwards if they noticed your presence, not referring to the flash but to your just being there. There is a good chance that they will not have even remembered the flash going off. I shoot in events a lot and if a flash is not direct, people tend to not even notice it. I'll show them a photo of themselves and they comment that they did not even know I was taking their photo. If I was to be so rude as to point a flash directly at their eyes from close range they would not be so happy with me, it IS very distracting. It also results in bad images. I think if you can find a suitable bounce direction that adds a few stops of light, all your problems will be over. Last night, bored, I dropped by a little bar and found they were big into Kareoke, which I hate, but stayed since everyone was friendly and having a great time on a Thursday night. I got out my camera from across the room and took a few shots. This one is of a biker who was actually a very good singer and a good conversationalist. It was ISO was 1000, f/2.8 1/100 and 200mm, hand held. Ambient light was very dim, and mixed source, mostly florecent beer signs. SB900, pointed up and directly to the rear at 45 degrees. Shot in JPG SOOC, and a 100% crop. Just to show that an indirect flash is not intrusive, he was very surprised that his photo was taken when I showed him after his song. There is a redish cast because the bounce ceiling and rear wall was painted a redish brown. You don't have much leeway in adjusting WB in JPG compared to raw NEF files. Stan St Petersburg Russia
