Digital painting from a pencil sketch

As an amateur and self-taught painter (I don’t like to call myself an artist) I always find it’s hard to adapt with graphic tablet, although I knew I have to get use to it if I want to make some nice digital drawings.

Fortunately, from David Revoy’s blog, there’s an article about how to turn my pencil sketch into digital drawing with some easy steps, all I need are :

  • Gimp ( I got the latest version ; 2.8.4)
  • G’MIC plugin
  • MyPaint, and Krita (optional)

And so I made this sketch, and uploaded into my computer with using my pocket camera, it would be better if I can use a scanner, but I don’t have it, but nevermind it.


First, open it with Gimp, choose from menu : Colors – Level , and adjust some setting just like in the picture below, to make the paper more white and the pencil sketch darker.

And then , open G’MIC plugin, and choose filter “PhotoComix Smoothing” , it’s at Testing – PhotoComix – PhotoComix Smoothing , ( if you don’t have it, maybe you have to update your G’MIC plugin first ) Just leave the setting as the default, the purpose of using this filter is to make the sketch look more smooth without loosing its sharpness.

To remove the paper from pencil sketch and make drawing transparent, choose Colors – Color to Alpha , and press OK.

Now, as the picture has turned transparent, Add New Layer with Layer Fill Type : White, and put that new layer in the bottom of the sketch layer.

Before I started to color my sketch, I change the layer mode into “Multiply” so the sketch line will more visible after I color it.

And I saved this picture with .ora (open raster file) so it can be opened in MyPaint.

At David Revoy’s blog , he used Krita to colored his drawing, I wish I can do that too, as I believe Krita is the most powerful digital software at this moment,  but I already enjoy using MyPaint, so here I just use MyPaint to color my sketch with only one layer !

What I love about MyPaint is it has very simple interface, so I can draw easily without any disturbance, and here I used Devaad Mixbrush (it called Deevad since it was made by Deevad, off course, hehehee ) I only use one layer to color this, but it would be much better if there are more layers, because using more layers will create a more realistic painting.

So this is the final result :


And that’s all about how to turn a pencil sketch into a digital painting, with using some help from these useful open source graphic software : Gimp, G’MIC plugin and MyPaint ! 😀

G’MIC Plugin

Colorize Comics, a great new filter from G’MIC

A few days ago I saw from G’MIC post at Google+ , there was a new filter : Colorize Comics , it was a very interesting filter, basically this filter can colorize your black and white picture (B/W) just by applying some colors in it, then the filter will do its job ; to extrapolate the colors into that picture.

Oh btw, G’MIC is a famous plug-in for Gimp, it has many amazing filters, until now it has more than 400 filters ! and you can have chat with G’MIC developers in Gimp Chat and Google+ , and off course they’re very helpful and friendly.

So how to use this filter ?

first, you have to install G’MIC, it’s very easy, just go to and download it.

After installing G’MIC, just open Gimp, go to menu bar : Filter – G’MIC ,there you have it !


But what happen if  there’s no Colorize Comic filter in G’MIC ?

No worries, you just need to update your G’MIC plug-in , just press that little blue “Refresh” button, and automatically G’MIC will update its new filters.


So first I tried to draw a picture :


then Add New Layer on the top of previous layer, with layer type : Transparency , then stroke some colors in that transparent layer just like this :


With that transparent layer selected, go to menu bar : Filter – G’MIC , then choose Color – Colorize Comics , on the left side you need to choose Input Layers to All , and just press Apply 

To make your B/W visible, you need to move that layer to the top, and change the Layer Mode into Multiply, and here’s the result :


Okay so this filter works very well in my childish sketch 😳 , but will it also work with “advance” picture ?

So I loaded my eye sketch, and I applied that same method to this pic :


And here’s the result ! Wow, awesome ! :mrgreen:


So for the conclusion, this Colorize Comics filter is very interesting and useful, especially for those who are too lazy to color some pictures 😀
