Processing Images from the Patagonia Trip.

I’ve been going back and processing images from the Patagonia trip. I’ve added a number of new images to the 11-January-2011 blog.

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 stiching 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

Magellanic Woodpecker.

Some images of a female Magellanic woodpecker taken while on the trail to Laguna Torres in Parque Nacionals Glaciares back in January (01-January-2011). We saw several of the these woodpeckers while going through a wooded area. This one was calm enough to pose and let several photographers take her picture.
