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.
