I just wanted to share an experience I had. My daughter dances with a professional company (Latin Ballet of Virginia) and during their latest, annual Christmas-time performance of "The Legend of the Poinsettia", I was called on to take pictures of the last show - at the last moment...
As a proud Dad, I usually go to relax and enjoy the performance but in this case I was working - in a tricky situation. I had never shot my D70 at 1600ASA but in this case I had no choice. I was very impressed. With a little help from noise reduction plug-in software called "Neat Image" (a life saver in this instance) I produced results like the one posted here.
Oh,...and going back to being the proud Dad, this is a photo of my daughter, Kelly, during that performance.
