Tutorial: create a paper clip with Gimp

final

Since it is a lot that I do not write a graphic tutorial, I thought I'd do it now. Today we see how "render" a metallica graffetta with Gimp. This tutorial (like everyone else so far) is suitable for a '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 bit 'cumbersome, 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.

The result so far this should be.

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 on the yield of glass or water. 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 deselect the image ("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 apply the light effect 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, go a little 'personal preferences. 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, smaller will be the printed image).

Of course, then you can add the background, one 'shading, or changing its outlook. As always, the variations are endless.
