Sometimes we take pictures that don’t turn out quite right or just rather boring. It is possible to rescue such images specially if they have a nice pattern.
Using free image editor like Paint.NET or Gimp, you can
section this image into several overlapping pieces. I will explain the overlap later.Edit each section and change its hue to the color you like. Set the saturation to get a more vivid color.
Now, going back to the overlap. Microsoft Windows Live Photo Gallery has a very smart feature that allows you to merge images with overlapping contents. It is basically a tool to create panoramic pictures out of several photos that you have taken.
I also suggest that you don’t retouch the section individually other that changing it’s color. You want to apply your finishing touches after all the sections are merged.
Here is the result after the merge and some cropping. Notice the three colors are now nicely blended, and the flower petals are now more noticeable. Click on the image to see the photo in higher resolution.
