when shooting indoors in fairly low light, how do you set yout camera??

[Daniel Browning]

Or by "manual" you mean setting th camer speed and opening manually and leave the flash in TTL mode?

I meant manual aperture and shutter with TTL flash. I'm not as advanced with flash as many other forum members around here. Here's on example: http://community.the-digital-picture.com/forums/t/2081.aspx

Also can you give me somewhat of a guideline on how to compensate or measure the effective range of the flash when it is bounced?

Really the only thing you can do once you hit maximum power on the flash is up your ISO and use faster f-numbers. If I need higher FPS (quick recycle time) or there are high ceilings, I wont hesitate to use ISO 3200 with flash, at least until there is too much contamination from existing light.

I don't have an external flash so I diffuse my onboard flash using opteka's diffuser. I also shoot in Av mode so I can control the f-stop, the shutter sits at 1/200 by default because the flash is on!
