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.
