Gone to See California — SIRNA Goodby.

While in the San Francisco area I had the opportunity to visit and have dinner with a couple of former colleagues that now live in the Bay Area. In the back yard one of their Yucca plant was blooming. There was a humming bird working the flowers. I never got a picture of the humming bird in the flowers, but did capture a sillouete of it in the some other trees. These images were all taken with a Leica X1 or D-Lux 5 camera.

Gone to See SIRNA — San Francisco.

I was in California to visit my team one final time before the South San Francisco SIRNA site shut down. We went out to lunch at Ambers, an Indian Restaurant. I took a picture of my team in front of the Contemporary Jewish Museum, just outside of the restaurant. I wished everyone luck in their future endeavors.

Red Canyon Petroglyphs. HDR Examples (HDR Express, Photomatix Pro, NIK HDR Efex, Photoshop CS5 HDR). A year ago, I attended the Eastern Sierra Photography Workshop led by Michael Mariant.

The following is an image of the petroglypths processed with Capture One Pro, Topaz, Nik Color Efex Pro, and Photoshop CS5. This is followed by a series comparing different HDR programs (HDR , Photomatix Pro, Nik HDR Efex Pro, Photoshop CS5 HDR Pro)

Let me know which if any HDR images you like or don’t like.

Two-Years Ago (14-May-2009) — California

Gone to See America 2009 Road Trip. Day 7: Spring in Yosemite National Park Photography Workshop with Michael Mariant.

I took this image 2 years ago while driving into Yosemite National Park. I noticed something bright red in my rear view mirror. This was not red flashing lights, but rather something red in the woods. I turned around and found these flowers blooming. I did not know what they were — a plant or fungus. They were later identified as Snow Plants (Sarcodes sanguinea). Although plants, they do not use chlorophyll for photosynthesis, but rather get carbohydrates from coniferous trees via a shared mycorrhizal fungus.
