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

Digital Editing — Comparison of RAW Image Converters.

Something a bit different. Today I am comparing 4 different programs that convert the RAW digital images acquired by my Nikon cameras. The RAW converters that I typically use include Adobe Camera Raw (ver 6.2), Nikon Capture NX2 (ver 2.2.6),  Phase One Capture One Pro (ver 6.00), and DxO Optics Pro (ver 6). The programs were all run on Windows 7 (64 bit). The image is one that I had taken on a Nikonians workshop run by Michael Mariant in Big Sur this spring.  The image was taken with a Nikon D3x and 14-24 mm f/2.8 lens (ISO 100, 14 mm, f/16, 2.5 sec) on a tripod. The overall scene was beyond the dynamic range of the digital sensor. It was rather dark in the forest, thus the long exposure. The bit of sky visible is bright (and blown out). In the following days I will be comparing some HDR (high dynamic range) programs to process several images of the same scene taken at different exposures to try to compensate for the wide dynamic range.

Adobe Camera Raw. This is the program that Adobe uses to process RAW digital images for Photoshop and Lightroom. Camera Raw is only able to read some of the Nikon in camera settings. In recent versions they have included settings that simulate the Nikon Picture Control settings (Landscape, Vivid, etc). The current version of Camera Raw also now includes lens corrections for a wide variety of lenses including the lens that this image was taken.
