w01 - Intro / Image Correction Techniques

Post by glegrady » Mon Apr 02, 2012 6:44 pm

Please post an image listing all the correction steps you have taken to adjust it using full image tools.

You should have explored the following:
- levels/curves for contrast adjust
- transformation for correcting parallax
- color balance for color adjustment
- image adjustment for saturation and brightness
- image size for reducing image to a manageable size and appropriate resolution for print or screen
- proper compression
There may be more functions - dont do any work on image details that require

Before and After images posted below:

-Transformed and skewed the image for proper parallax.
-Adjusted color balance, curve, and desaturated the image some to add a more suitably oppressive atmosphere for the image (photo was from Pripyat, a town that had been abandoned for 30 years after the Chernobyl incident).
-Reduced the size of the image from 4097x2726 to 1024x681 pixels.
