Four-Years Ago (31-July-2011) — New Jersey

Backyard Summer Nighttime Sky Over New Jersey.

Star Trails taken by three cameras. (1) Looking North: Nikon D3s camera and 24 mm f/1.4 lens (ISO 400, 24 mm, f/4, 30 sec). (2) Looking South: Nikon D3 camera and 24 mm f/3.5 PC-E lens (ISO 400, 24 mm, f/4, 30 sec). (3) Looking South and Up: Nikon D3x camera and 14-24 mm f/2.8 lens (ISO 400, 14 mm, f/4, 30 sec). One hour composite star trail images. Dew settled on the 14-24 mm lens making the center of the image darker and making it look like there are few stars.




Individual images from the slide shows can be viewed here.

Seven-Years Ago (31-July-2008) — Colorado

Summer Nighttime Sky Over Colorado.

Star trails from my room at the Marriott Residence Inn in Boulder, Colorado. Composite of 180 images taken with a Nikon D3 camera and 24 mm f/3.5 PC-E lens (ISO 200, 24 mm, f/5.6, 30 sec exposures). Raw images processed with Capture One Pro 8, and combined using Photoshop CC 2014 (scripts, statistics, maximum). Note that these images were taken using the in-camera intervalometer and noise reduction so for every minute, only 30 seconds of exposure. I’ve learned how to do it better since then — using an external intervalometer and doing the noise reduction post processing.

Two-Years Ago (30-July-2013) — Iceland

Gone to See Iceland 2013 Photography Safari with Mike Hagen. Day 1: Golden Circle.

The Bubble is About to Burst. Strokkur, a geyser in the Haukadalur geothermal area beside the Hvítá River in Iceland. Images taken with a Nikon D4 camera and 80-400 mm VRII lens (ISO 100, 80 mm, f/11, 1/320 sec). The great thing about this geyser is that it erupts several times an hour, and you can get to relatively close safe distance. All of the Golden Circle bus tours stop here, so it can be crowded.
