David Mathre Photography

Welcome to my Images of the Day Photo blog. My goal is to post images from each day of the year going back to 2006 when I got my first DSLR camera. My photographic interest include Travel, the Natural World, Landscapes, and Photographic Techniques. I try to include information for each image as to where, when, why and how the image was processed. Most of the images are available for purchase -- either as prints or rights managed (Clicking on an image brings you to the ShepArt Studio Team Site). Comments about the images or this site are always welcome. DJM

Comparison of Digital Noise Reduction Programs. Pre-dawn view of the Moon, Venus (and Mercury) over the Pacific Ocean. 

While sailing south on the M/V Explorer last month, we were told by Professor Ian Campbell to look for the moon and several planets in close proximity. Here are a couple of images taken with a Nikon D3x amd 85 mm f/1.4 lens (ISO 1600, 85 mm, f/1.4, 1/30 sec). I needed the high ISO to even get a 1/30 sec exposure since it was still dark and the ship was moving. For each image I processed with no digital noise reduction, then with either NIK Define 2.0 or Topaz DeNoise 5.0.

Check out the updated 30-April-2011 post for more images from day 4 of the 2011 Spring Enrichment Voyage/UTW-II.
