Re: Ideal settings for low-light on a Canon 60D

I think it'll be pretty easy to get more light...
You're shutter (typically) should be 1/(fps*2).
24fps - 1/48s (1/50 for most HDSLRs)
30fps - 1/60s
60fps - 1/120s (1/125 for most HDSLRs)
This is the equivalent of a 180 degree shutter angle.

Off the bat you could have achieved at least twice as much light by reducing your shutter.

The biggest limiting factor is your lens obviously. An f/4 just is not made for low light. An f/2.8 (common for zooms) would have given you twice as much light and of course on the extreme side, an F/1.4 (common for primes) would have yielded 8 times as much light on the sensor.

If you had adjusted shutter and had an f/1.4 lens you would have had 16 times the light compared to your current exposures. You also could have decreased ISO to 1600 and still had 4x as much light and less noise (though overexposing is one way to help ease noise).
