A comparison between Under the stars in the snow 101 and 102


The first two pictures of my Flickr set titled Under the stars in the snow are a comparison of photo editing techniques.  Under the stars in the snow numbers 101 and 102 were created from a single digital photographic exposure.  After the camera sensor had collected the light on the scene for 30 seconds an image file was created on my CF memory card.  The details of the creation of the image are recorded in the Exif data.  The Exif details are available to view in Flickr if the photographer has allowed them to be seen.  The details for my images are available on Flickr if you use the drop down menu from the, “Actions,” tab you will see the option to, “View Exif info.”

Under the stars in the snow 101 - Exif details - (some not all)

Camera Canon EOS 5D Mark II
Lens EF16-35mm f/2.8L II USM
Exposure 30 seconds
Aperture f/9.0
Focal Length 16 mm
ISO Speed 800
Exposure Bias 0 EV
Date and Time 17 December 2010, 9:47:31 PM

This original image was then processed in two separate ways.  Under the stars in the snow101 has had Vibrance, Gamma and Brightness increased to create a greater glow all along the horizon than that presented in Under the stars in the snow 102.  In the midst of the dark night scene the glow of Under the stars in the snow 101 is rather bright indeed.  Under the stars in the snow 102 has had less of increase and it more closely resembles the view as seen by my eyes.  In general I only load one version of any single exposure.  Often I will show more than one exposure when I have altered the camera settings between exposures.  It is good to compare the effects of shutter speed, light sensitivity and aperture settings on pictures that are taken in a single photo session.  Sometimes it is also good to see just how basic differences in photo editing settings completely change a scene.
