More firefly trails. I found that I can do exposures longer than 30 seconds on the Fuji X-H1 camera. However, at the cost of more sensor noise. The image required more post processing to remove the red and blue noise pixels.
Backyard Fireflies. Composite of 110 images taken with a Nikon D3s and 600 mm f/4 lens (ISO 2500, 600 mm, f/13, 25 sec). Images processed with Capture One Pro, Startrails (used to stack the images), and Photoshop CS5.
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.
