On camera flash

There is nothing wrong with on camera flash. There is no taboo about it. Learning how to do it right and consistently is key. As far as assuming the OP didn't need flash at ISO 1000, without being there how do you know? In my house at night I'd need iso 3200 to get a decent shutter speed at anything smaller than f/2.8. To the OP I'd recommend getting Neil Van Niekerk's "On-Camera Flash". You can also check out his tutorials atwww.planetneil.com. There is a lot more to on camera flash than bouncing it off of the ceiling or flashing it through a piece of tupperware.

Scatter, thank you. I have read Neil Van's tutorials on the web... this guys is awesome and yes, there is a lot more to on camera flash that bouncing it off the wall/ceilings (I feel like it's a science in itself....lol).
The lighting in the room where the shot was taken is really poor (flood lights) so I needed to bump the ISO in order to capture the ambient light.
