it looks like the venue was inside some shopping centre.
I guess you used flash, but the lighting is still not too bad, I guess these are around ISO400 1/200 f/5.6?
What film did you use?
I'm about to shoot a dance performance (of a SYF gold dance society) this month, it will be in some theater in NUS. I prepared to use NPH400 with 135/2 50/1.8 and may push a stop if needed. I do have some 80B & 80C filters, but still hope that I will not get tungsten lighting.
