Today, I will show you how to add smoke on top of a chimney thanks to paint.net and few plugins.
First, here is the starting picture :
As you can see, it has a very nice chimney from which we will make smoke emerge.
Here are the steps to add smoke on this picture :
1/ Add a new layer (CTRL + SHIFT + N);
2/ Select the area next to the chimney top with the ellispe selection tool (S key);
3/ Apply a cloud effect (Effects menu > Render > Clouds) with the following values : scale at 110 and roughness at 0.90;
4/ Deselect (CTRL + D);
5/ Apply a motion blur (Effects menu > Blurs > Motion blur) with the following settings : angle at 90° and distance at 80;
6/ Apply a SinWaves effect (Effects menu > Distort > SinWaves) with these params : amplitude at 5 and horizontal period at 15. This effect will create the wave aspect of the smoke.
7/ Apply a gaussian blur (Effects menu > Blurs > Gaussian blur) with a radius of 2;
8/ Apply a glow effect (Effects menu > Photo > Glow) with the following values : radius at 5, brightness at -15 and contrast at 45;
9/ Switch the layer blending mode (F4 key) to screen mode;
10/ You can perform a gradient (S key) on the smoke density (in order to simulate the dissipation) with the following values : transparency mode and linear and then perform the gradient from bottom to top.
Here is the final result of the house with the smoke coming out of it :
To perform this tutorial, you will need the following paint.net plugin :
le magical plugins megapack.
The nice thing is that you can reuse this technique for other contexts such as a cup of coffee, a cigatte, a fire, etc…
To write this original tutorial, I started from this tutorial photoshop that I have adapted to paint.net with few modifications.
