Here's a couple of lucky shots straight outta the SD card. This is my DIL who came to perform at the Quincenera with my stepson and stilted on the dance floor. She's a pro stiltwalker (how many families can say they have one of those in the ranks?) and she was spinning LED arrays. Room was very dark so I cranked ISO to 16,000 and guessed on F/stop and shutter speed. This is the result, more of these to come.
