Late-Winter Indoor Nature in New Jersey. Stink Bug.

I have gone the entire winter and only saw a couple of Stink Bugs in the house. So tonight, while cooking dinner this Stink Bug decided to become a target while I was cooking dinner.

Just wondering if anyone is viewing my “Image of the Day” photo blog”. I have not posted anything for the last month, and didn’t get any feedback wondering where I was or if there would be more posts. The blog has been getting 20-40 spam messages a day to older posts, which I do not pass forward. At the same time, I have been posting images almost every day to Google+, mainly to various “Daily Photography Themes“. For these posts, I get many pluses (+) and comments. I am trying to figure out if there is a real audience to “My Image of the Day” photo blog. Please comment either to this blog or by e-mail.

Backyard Winter Night Sky in New Jersey: Star and Jet Trails.

I used a 16 mm Fisheye lens to take acquire some winter night sky images. The images were combined using the startrails.exe program to get the star trail images. The first image is a composite of 15 60 second images relatively early in the evening. The next three are composites of 16, 35, and 300 second (5 minute) images.

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.

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 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

Photo Techniques. High Dynamic Range (HDR) Image Processing.

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.
