One 'trick' in editing a photo is to focus on the dominate color in a shot. Today I took two photos at lunch. The first photo was centric on the color blue. The second was not a shot centered on the color, but when editing out the other colors the shot took on a new feeling.
The primary colors are the best to use, or some shade of those colors. Blue is a common color to focus on since the sky (and reflections of the sky) are normally a shade of blue.
The photo on this blog entry is of a New Orleans porch with a Lavender-Blue theme. When editing the photo all other colors were removed.
Discovered in Nola while walking to lunch.
