The weather held, and I got a second chance to capture an image of the fireflies flashing in my backyard. This time I set up two cameras, reduced the aperture (so a greater distance would be in focus), increased the ISO to increase the brightness (dealt with the increased noise in post processing), and set the focus distance to ~70 feet (locking the focus ring with gaffer tape). This time the composite images were better. I will try again tomorrow.
Fireflies in my backyard. Composite of 110 images taken with a Nikon D3s camera and 600 mm f/4 VR lens. I liked this image, and used the camera parameters to help my efforts to get better images tonight.
It was relatively dark out, and I could see a large number of fireflies out my backyard. I set up a camera, and took a series of images which I used to create a nearly two hour composite image. I am not happy that all of the fireflies were out of focus — I didn’t guess right with the distance from the camera and/or the focus dial moved as I was setting the camera up in the dark. Weather permitting I am going to try again tomorrow night.
Another composite image of fireflies in my backyard. This time with a telephoto lens at f/13 to try to get a deeper depth of field effect. As before, the camera was set up to take 25 second images, and the resultant 110 images combined using the Startrails program.
