Great shots Darkburst. Integra, I'm with you on the no flash too. Like Darkburst said, flash flattens so much, very often. It can be used artfully, but I prefer natural lighting when photographing stage acts. I let their lighting techs do the work and I try and capture that mood.
This one was shot at F 5.6 and still did not have enough Depth of field though. That can be a problem with small apertures and F5.6 is not even small. This was shallow DOF wise because I was at 300mm and even with IS, it was a challenge.
Here's one, Ok, two combined. Sigma 20mm 1.8 lens f 2.5 1/50 sec.
Black lights and other light providing the kelvin.
Natural light rules!
