David's Images of the Day Photoblog
Views of the land around the world
This was the beginning of the extended family winter vacation in Norway. Our first full day was in Oslo. Some of the children in the group had never seen snow before. A long day with many things to see and do as well as adjust to the time difference.
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.
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
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.
