GIMP – Using Colorize

Lets suppose that after a trip skiing, you realize that a few of the photos didn’t turn out as you had hoped.  You can’t just go back and take the photo again easily, so you’ll have to clean it up a bit.  In this case, I’m pretty sure that the white balance was off on my camera.  This caused many of my photos to turn out with a turquoise tint to them.

While there are many ways to approach fixing this, I had the best luck with GIMP’s Colorize tool. This tool give you the ability to adjust the image’s Hue, Saturation, and Lightness.

Adjusting the hue up will add more red to the image, while down will add more yellow.  Less saturation will essentially remove color from the image, and more saturation will make the colors more profound. For my case, even though I wanted the snow and lights to be nearly white, I didn’t want it to be completely white.  The adjustment to the hue managed to change most of the turquoise to a blue and once the saturation was turned down, the blue was left just as an accent.
