Tutorial: The technique of “split-toning” with Gimp
The technique of split-toning consists in altering the natural colors of an image. Today we will see how to apply this technique in a few easy steps with Gimp. To understand this with an example photo shows the "before"And"after"Operation. [more]
First we choose a beautiful photo Whose su operating. Best if taken by us, otherwise Flickr and Panoramio are inexhaustible sources of photographs (if you publish them eye to comply with the licenses).
Open the photo with Gimp and start duplicate the layer.
Selecting the first level in the hierarchy "desaturiamo"Making black and white. “Colors” – “Desaturation”. Let the basic settings and click on "Desatura”.
We create a new level and we fill blu. As I used the blue "2bc6ff”.
Now change the layer mode to "Overlying”.
Once the level superimposed, it 'merge in low"With the black and white.
Repeat the same operation, always with the initial level: Duplication level, desaturation, creating new level. This time the newly created layer will be filled with yellow, the "ffc600”.
Now apply a layer mask to the yellow level "copy of the level grayscale”.
The same thing is repeated also on the blue level, with the difference that in the window of the layer mask flaggheremo "Invert Mask”.
To finish the job, you can play a little with the 'opacity of the layer. Depending on the photo it will take more or less opacity.
For perfectionists recommend you play the levels.
