Since it is a lot that I do not write a graphic tutorial, I thought I'd do it now. Today let's see how to draw one metallica graffetta with Gimp. This tutorial (come tutti gli altri fin’ora) è adatto ad un’medium-expert users the program Gimp, I do not exaggerate to declare the most famous Graphics software open source.
We will use a technique honestly a powder’ macchinosa, but already seen nearly a year ago: Give the glass effect / water with Gimp.
For the realization of the tutorial requires from 5 to 15 minutes, depending on the level of user. The result will be.
We begin to create a new file, dimensions 800 x 600 px background white.
We select the “Path tool” and begin to draw the staple.
Now let's create a new level transparent the tab of the layers and call it “paperclip“.
Now, tab in the Brushes, select a round toe with blurred margins.
We now go to the tab of the tracks and click the button “Draw along the route“, the dialog box, select “Outlines with a tool“. In this case, we leave the brush tool.
Il risultato fin’ora dovrebbe essere questo.
We invert the color Staple with “Colors” – “Invert“.
From this moment on, we can follow most of the instructions I have already given in tutorial sulla resa del vetro o dell’acqua. Here we go.
First of all levels in the tab click with the right on the level “paperclip” and select “Alpha to Selection“.
Then we go to the tab of the channels and it create a new one channel initializing it from selection as shown in figure.
Also from the tab channel deselezioniamo l’immagine (“Ctrl” + “Shift” + “A“) and apply different blur- “Filters” – “Blur” – “Gaussian“. Respectively from 7, 5 and 1 pixel.
At this point we make invisible the channel and applicare l’effetto luce to give depth to the clip. “Filters” – “Light and shadow” – “Lighting Effects“. Activate the bump map selecting the channel on which we just worked.
The parameters of the tab “Light“, instead, vanno un po’ alle preferenze personali. Below I point out the ones I used, but nobody forbids to change them at will.
The result will be.
At this point we have our graffettina ready to be adapted to our needs. I found an ad use in some templates, or for printing with different values (the higher the dpi, più piccola verrà l’immagine stampata).
Of course, then you can add the background, a’shading, or changing its outlook. As always, the variations are endless.
