Gone to See America 2010. Big Sur Photography Workshop with Michael Mariant. Day 1: Afternoon/Evening.

For the Afternoon, we spent time at Redwood Gulch Falls. The light levels within the forest near the falls ranged from very bright to very dark — well beyond the capability of DSLR sensors. Here I used Singh-Ray filters (to smooth out the water flow) and HDR (took 5 images under and over exposed) which were then combined using Photomatix. Later on we traveled to Sand Dollar beach. Our first exercise was to use filters at the beach to give the waves a soft ethereal effect. As the sun set over the Pacific ocean, I used HDR again to adapt to the wide range of light.

Troll Family Portrait: Helicon Focus

Macro focus stacking study using Helicon Focus. This is a composite of 30 stacked image where the focus was adjusted near to far using Helicon Remote and then combined using Helicon Focus. The images were acquired using a Nikon D3x camera and 5o mm f/1.4G lens (ISO 100, f/1.4, 1.3 sec) and ambient light.  The distance between nearest and farthest focus point was ~5 inches, and the camera was ~24 inches from the nearest focus point. The Helicon Focus settings used to process the images were mode B, radius 8, smoothing 4. Other settings increased the halo.

Gone to See Hawaii, Maui Day 1: Surfer Girl at Hookipa Beach.

This was the only day while in Maui that the surf was good. After coming down from Haleakala National Park, I spent a the later part of the afternoon at the Hookipa beach overlook watching and taking images. This image was taken with a Nikon D3x and 70-300 mm VR lens (ISO 200, 300 mm, f/8, 1/400 sec). This is a significant crop (1873 x 1249 from the original 6048 x 4032) as the action was quite a distance from the overlook. I was very impressed with sharpness the 70-300 mm lens.
