Images from Hosteria El Pilar and a Hike to El Mirador and Laguna Torre.
We stayed several days at Hosteria El Pilar near El Chaltén in Argentina. With the constant wind and extreme weather, the trees in Patagonia take on some unique shapes. After a long hike, there was a rainbow visible from the back porch at the Hosteria.
Double Rainbow. While driving from Zion National Park to Bryce National Park on Utah Highway 12, I noticed a dark sky and then a rainbow in my rear-view mirror. I stopped along the road just outside Canyonville and started to take some pictures. It was great that I had a dark background so I could see the double rainbow. By the time the rainbow was done several other cars stopped. I was the only one with a tripod, which was good since I could take several exposures for later HDR processing.
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.
