Today we see how create an effect "starry sky"With GIMP. This guide can ever be of assistance to dial one background for pc, but also and especially for greeting cards, Tickets, posters, folding and products for typography in general. If the final destination of the image will be the screen Computer (background, but also web page or web gallery) advice 72,00dpi. In case the requirement was the carta stampata I suggest the 300,00dpi (to maintain high resolution).
First, create the image of the desired size. “File” – “Fresh”, e which we set the dpi by clicking on "Advanced Options” (72 Screen, 300 for paper). As an example I will use the size 800×600 a 72,00dpi.
We begin to color the background in black. Soon after we create a new transparent layer with the appropriate button in the Layers dialog leaving the settings that are unchanged.
We will work on this level to create the stars. Come on "Filters” – “Disorder” – “Chance"And always apply with the settings given.
Now that the colored dots are all we have "discolour"Acting only on Grayscale. In this way, the stars will be all white. “Colors” – “Desaturation”.
Too white, is not credible. “Colors” – “Brightness and Contrast"And set the brightness to"-112"And the contrast to"127”.
And now imposteremo l 'glow effect all agency. “Filters” – “Light and shadow” – “Twinkle"And set l '"intensity glitter” a “0.20”. Everything else unchanged (unfortunately the screen from 8.9 inch does not allow me the full screenshot).
The work is almost finished. We add a new level as before and begin to create mist effect made. “Filters” – “Render” – “Clouds” – “Solid Noise”. The dimensions "X"And"And"Should be set to"3.9”.
Now we're going to act on the layer stacking, modifying the way down the appropriate. Select "Lighten only”, and we set l '"opacity” a “9.5”. The curtain can find it at the top of the Layers dialog where usually it says "usual"As follows.
And here is our background (a bit petite, but very clear) ready to be saved as jpg.
