Elderhostel “Photography in the Southwest” Workshop Day 1. Star Trails.
The following image is a composite of five 30 minute night sky exposures taken during a Elderhostel/Road Scholar photography workshop at Kelly Place outside of Cortez, Colorado in 2008. It was really dark other than the Christmas lights at the main building, and you could see a lot of stars in the sky. I moved the tripod as far away from the lights as possible and decided to do this series with a fisheye lens that would give a 180° field of view. The five images were combined using Startrails. This program is old (only works with jpg or 8-bit tif files) but works better than when I try to merge the images as layers in Photoshop.

Backyard Winter Nature in New Jersey: Turkey Vulture and Using Focus Magic to Remove Motion Blur.
I often use Focus Magic to sharpen images. I prefer using this program since it uses a deconvolution algorithm to sharpen the image, rather than unsharp mask (USM). Here is an example where I used Focus Magic to remove motion blur. On the down side, Focus Magic has not been updated for some time and only runs as a 32-bit application. I can only use it as a plugin in Photoshop CS5 when running the 32-bit version of CS5. For this example I am using an image of a Turkey Vulture in flight (from four-years ago). I tried to improve the sharpness of the head, eye, and beak. The 2nd and 3rd image are 1:1 zooms of the head — first without removing the motion blur, and the second with the motion blur removed (350°, 9 pixels). The results are not perfect, but better than the original image. One of the reasons I do not delete images — new software can sometimes be used to recover and image that previously would have been rejected.

Gone to See Hawaii, Maui Day 3: Haleakala National Park.
Sunset over Haleakala Satellite Tracking Station: Comparison of HDR Image Processing Programs. I used images taken at sunset last year to do a comparison of HDR (high dynamic range) processing programs. The first image is the original image taken with a Nikon D3x and 24 mm f/3.5 PC-E lens (ISO 100, f/16, 1/10 sec). The next three images are HDR composites from 5 exposures (+2, +1, 0, -1, -2 EV) using Photoshop CS5 HDR Pro, Photomatix Pro, and Nik HDR Efex Pro. The final image was processed using DxO Optics Pro 6 using a “single-shot” HDR technique. All of the new HDR programs have multiple, if not many presets as well as many controls to optimize the image. The HDR programs have come a long way over the last 3-4 years, where the HDR effects were often overboard. But then again, HDR can recover an uninteresting image i.e. “A derelict fishing boat along the Alaska Canada Highway”
