Travels around the world

Three-Years Ago (19-November-2007) — Hawaii

Gone to See Hawaii. Big Island Photography Workshop with Thom Hogan. Day 2: Morning Session.

Image Processing Techniques. A comparison of different HDR (high dynamic range) programs for rendering a series of images 7 images taken at different exposures (+3, +2, +1, 0, -1, -2, -3 EV). The programs compared are Photoshop CS5, Photomatix Pro, and Nik HDR Efex Pro. I should note that I am not able to run the Nik HDR Efex Pro on my desktop computer as it causes Photoshop to crash. I had to use a different computer to process the images using the Nik HDR Efex program. The images were taken with a Nikon D2xs camera and 105 mm f/2.8 VR macro lens.


Thursday (05-August-2010) — California

Gone to See America August 2010 Road Trip. Day 5: Eastern Sierra Photography Workshop with Michael Mariant.

A few images from the first day of the Eastern Sierra Photography Workshop with Michael Mariant. I actually missed the first locations that Michael took the group to earlier in the day since I was traveling from San Francisco (visiting my group as part of my day job). Michael provided me with the GPS coordinates for the Red Canyon Petroglyphs so I could meet up with the group for the petroglyphs and then sunset over the Owens Valley. I took the following images of the petroglyphs soon after meeting up with the group. You can tell that there has been vandalism as folks try to add their own “art” or have taken parts of the ancient art away.

We spent the day doing a walkabout in St. Georges. The objective for the day was “street photography”. Three of the main churches were still missing their roofs after a hurricane several years earlier. This photo is of the pastor at the Episcopal Church.
