One-Year Ago (10-January-2011) — Chile

Gone to See Patagonia 2010/2011. Photography Workshop with Thom Hogan. Day 15: Torres del Paine National Park, Departing Hosteria Lago Grey Chile.

Early Morning Double Rainbow in Patagonia. Comparison of HDR (High Dynamic Range) Processing Programs. Digital camera sensors are not able to deal with the full dynamic range that the human eye can process. The same is true with computer monitors and printers. There are several commercial programs that will combine over and under exposed digital images to provide a composite digital image that tries to express the wider dynamic range of the eye. I continue to evaluate the commercial HDR programs. The following images are of an early morning double rainbow taken at Lago Grey in Torres del Paine National Park in Chile during my Photography Workshop in Patagonia with Thom Hogan (10-January-2011). The inital image is the original single exposure. This is followed by four HDR images processed with 1) Photoshop CS5 HDR Pro, 2) Photomatix Pro, 3) Nik HDR Pro, and 4) HDR Express Pro. Please reply with comments on which HDR image you like or don’t like.

Composite Panorama Image Processing.

There are several image processing programs available to combine images to afford wider panorama images. The images of Laguna Torre were taken on a hike from El Chalten in Parque Nacional Los Glaciares while on a Photography Workshop in Patagonia with Thom Hogan on 01-January-2011. Three examples shown below have four portrait orientation images combined using Photoshop CS5, AutoPano Giga 2.5, and PTGui. All three composite images were cropped to the largest rectangle: Photoshop (11865 x 5814), AutoPano (12572 x 6266), and PTGui (12091 x 5979). Photoshop did the best job in minimizing the stitching artifacts in the water. AutoPano Giga did the best job in including the most image area — our hiking guide in the far lower right corner of the image is not cut off

Photo Techniques. High Dynamic Range (HDR) Image Processing.

I continue to evaluate and compare several HDR processing programs. The images were taken on a hike from El Chalten to Laguna Torre in Parque Nacional Los Glaciares while on a Photography Workshop in Patagonia with Thom Hogan on 01-January-2011. The first three images are composites of 5 images processed with Photoshop CS5 HDR Pro, Photomatix, and NIK HDR Efex Pro. The last two images are single image HDR processed with Capture One Pro and DxO. Of these I like the image from NIK HDR Efex Pro best.

Gone to See America. December 2011 Florida Road Trip. Day 2: Merritt Island National Wildlife Refuge.

After arriving at my hotel in Cocoa Beach I drove to Merritt Island Wildlife Refuge. It took about 40 minutes to get to the headquarters to buy a new America the Beautiful pass. They were going to give it to me for the senior rate of $10, but to be ethical I paid the full price. I then went for one round through the 7 mile, one-way Black Point Wildlife drive before sundown. They close the road at sunset. The following are some images I took along the road.
