I'm naturally averse to using high ISOs. Blame it on my days as a film photographer shooting landscapes. The grain (or noise) associated with pushing film to the upper limits of speed was a price that I was seldom willing to pay. I determined never to go beyond 400 ISO. That "speed limit" was something I carried over in the switch to digital.
I'm more willing now to pay the price for the ability to shoot in low light conditions. Being paid to cover events and weddings in less than ideal lighting does that to you, I guess. You do what you gotta do to get the pictures people want. 800 ISO became my new friend, along with a software program designed to reduce digital noise.
This fella was shot at 1600 ISO -- formerly a no-man's-land for me. A very small amount of on-camera flash was used to give the bird a catchlight in its eye, but that's all. The heavy lifting was done by my camera's sensor.
Not sure that I'll make a regular practice of shooting at 1600, but with photography, at least, I've learned to never say never.
