Fireflies in My Backyard.

Yesterday was the first day of summer, and my backyard is full of firelies. I set up a camera to take 25 second images, and then used the Startrails program to combine ~150 image (ISO 400) for the first image and then ~100 images (ISO 6400) for the second image. The D3s can see in the dark, and I didn’t take it all the way up to 100K ISO.
