Was this machine washed? Or is that 7d that good on low light?

It's extremely good in low light and this is how the exposure looked in terms of light. Slight radial blur on the top half to give clouds movement and layers blended. The G1X is better and I suspect the 5D MkIII will be better still.

I no longer use my 20D in anything except bright light as it can't touch the newer sensors.
