The first image, that I’ve tried to fix is the one below, with a single flower whose petals are too weakly colored in the original shot.

Image Initiale
Original shot

The image that made its way to my gallery suffers from over-saturation, because I only applied global changes on the white balance and the overall contrast, which was probably not well suited here (or at least not enough).

Image over-saturated
Flower with overly saturated colors.

To get a better result (with Gimp), the easiest way is to use the layers and layer masks. This technique is well explained in the MeetTheGimp[en] podcast (for instance in the  latest episode[en]).

Masque de calque
A layer mask isolating the flower.

So layers make it possible to work with several images superimposed, and to control the transparency effects 1. Here, only two layers were needed: a image of the origianl shot, modified in order to make the greenish background darker and an image of the same shot but where the colors and luminosity have been enhanced. Using a layer mask on this second image, made it possible to keep the modifications only on the white regions of the mask. Thus, I could modify the color of the flower independently from the background. Images below show three examples of such modifications.

Pétales légèrement réhaussés Fond assombris indépendemment des pétales Fond quasiment invisible

A good occasion for me to learn about macro photography (“only” 100mm for now).

Here is a small sample (the full gallery is accessible by clicking on the image):
