Night Sky in Patagonia.

I got up really early before dawn to see the night sky in the southern hemisphere. I’ve wanted to see the Southern Milky Way and the Large and Small Magellanic Clouds. This was the first time that I saw the Orion constellation up side down. I don’t recognize many of the other stars and southern constellations. Images from my Patagonia photography workshop with Thom Hogan while staying at Hosteria El Pilar in El Chalten in Argentina.

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 a 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.

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.
