chromed Bumpmapping

Shrinking selection in 3px steps, then converted to a path, stroke by 1px and blurred by 2px as the bumpmap.

Chrome curves, 'anisotropic smoothing' and 'Light Glow'.

In this version i tried to get the same effect with Lighting effects, using the bumpmap, but for some reason the filter doesnt recognise much detail.
It was good for adding colour though.

The cushion effect comes from the G'MIC Relief Light filter.

BumpMapping Level II

I think there is a lot of potential in bumpmapping that is overlooked and today im going to show you how you can add some complexity to the basic technique.

The key element of bumpmapping is blurring and as all my gimp-scientist-padawans know, blur means you can shape it with an alpha-curve ! :)

Chrome Curves

I already posted a tutorial about alpha-curves that are good for shaping the alpha-channel. In this tutorial its all about Value or Chrome-Curves.
The channel of the curves-tool is set to the default of 'Value' (instead of Alpha).

Chrome-Curves are a way of shaping a gradient (for example), into something that looks metallic or chromed.
