David's Images of the Day Photoblog
November Full Moon — Also known as the Beaver Moon or Harvest Moon. 1) Image acquired with a Nikon D3x camera and 400 mm f/2.8 with TC-E 20 teleconverter (ISO 100, 800 mm, f/8, 1/250 sec). 2) Image acquired with a Nikon D3s camera and 400 mm f/2.8 with TC-E 20 teleconverter (ISO 200, 800 mm, f/16, 1/100 sec).
Comparison of RAW image converters. Waipi’o Valley is located along the Hamakua Coast on the northeastern coast of the Big Island of Hawaii. The image was taken with a Nikon D2xs camera and 12-24 mm f/4 lens (ISO 100, 17 mm, f/11, 1/200 sec). Four different programs were used to render the RAW image: 1) Capture NX2, 2) Photoshop CS5 with Camera Raw 6.2, 3) Capture One Pro 5, 4) DxO 6.5. The images were rotated 2.6° to level the horizon, sharpened with Focus Magic, and then converted to jpg and sRGB with Photoshop CS5. I am interested in feedback regarding the different renderings.

Waxing Gibbous Moon (97% full). Image taken with a Nikon D3x camera and Questar 7″ telescope (ISO 200, 1600 mm, f/16, 1/200 sec). Image processed with Capture One 5, Photoshop CS5, Focus Magic, Topaz DeNoise.
Image Processing Techniques. A comparison of different HDR (high dynamic range) programs for rendering a series of images 7 images taken at different exposures (+3, +2, +1, 0, -1, -2, -3 EV). The programs compared are Photoshop CS5, Photomatix Pro, and Nik HDR Efex Pro. I should note that I am not able to run the Nik HDR Efex Pro on my desktop computer as it causes Photoshop to crash. I had to use a different computer to process the images using the Nik HDR Efex program. The images were taken with a Nikon D2xs camera and 105 mm f/2.8 VR macro lens.
Gibbous Moon. Image taken with Nikon D3x camera and Questar 3.5″ telescope (ISO 100, ~ 1600 mm, f/16, 1/60 sec). Processed using Capture One Pro 5 and Photoshop CS3. With the smaller telescope I used the mirror up setting on the camera to dampen mirror vibrations for 30 seconds before taking the image.
