Color Adjustment
By: attator
Adjusting the colors of an image also changes its actual or perceived luminosity. If it's only the image's color that needs adjusting, this can be done without touching the luminosity (contrast, brightness) by instructing the software to limit the adjustment only to colors. RAW format processors, for example, usually have an option to apply noise reduction only to colors, thereby instantly solving the problem of chroma noise while preserving the texture of the image. In Photoshop, it's also easy enough to duplicate the main layer and assigning the new layer as "color" and do all kinds of color shifts and adjustments to this color layer. Still in Photoshop, just before saving the file in jpeg format, while still in the color layer, a simple localized gradual desaturation can be applied by running repeatedly (as many times as required) an action that goes:
* select - color range - out of gamut (to adjust only colors that are out of bounds, leaving the rest in their full colorful glory)
* select - modify - expand - a few pixels / select - modify - feather - a few pixels (to avoid banding)
* modify - image - desaturate - a few levels down
Repeat as necessary.
Photo above was taken in Miami on a recent trip, I used the above process to push it to maximum saturation without going out of gamut.
