tonight I thought I'd finish off my tutorial/guide to how I put together cartoons for my other site (www.satiricalblog.com) using Inkscape and Gimp2.
Which can be found here:-
The first part focussed on the use of Inkscape to trace an outline (and can be found here Part 1)
The second part looked at using GIMP2 to colour the sketch (and can be found here Part 2)
This third part looks at continuing to use Gimp2 to provide a bit of shading to the cartoon.
So here's where we left off last week...
The first step it to reorganise the layers of the picture.
Dragging the original image layer to the top of the Layer Stack in the right hand window.
Once that is done I hide all other layers (clicking on the icon) leaving just the original picture.
This is what I'm going to use to provide the shading to the image after a little manipulation.
From the 'Colours' menu I select 'Desaturate...' usually accepting the default options in the window that pops up.
Next I want to enhance the contrast using the 'Brightness-Contrast...' option in the 'Colours' menu.
...using the sliders to just bring out all the areas of light/shade.
So far so simple.
The next steps involves using blur filters and posterise function to produce a simplified shading map for the image.
In the 'Filters' menu I select 'Blur' and then 'Gaussian Blur...'
...and then I adjust the sliders until I've got a suitable amount of blur.
This tends to be between 2-5 px depending on the size of the image.
Essentially what this step does is take out some of the fine detail, blurring together smaller areas of light and shade into larger areas.
Next comes simplifying this layer using the 'Posterise...' function from the 'Colours' menu
...using the slider I normally go for about 4-6 colours/levels of grey, what ever looks best for the image.
Now I have my shading map the next step is to overlay this on the cartoon image.
So while still on the, now black and white, shading layer I change the layer mode from 'normal' to 'soft light'.
And drop the 'Opacity' a little...
...then I make visible all the other layers
...and all that is left is saving it.
Giving the final result:-
So there you have it, how I cheat at being a cartoonist.
