effect

The script makes a pencil drawing from a photo. It's very easy to handle.
The original tutorial can be found here: http://www.gimpusers.com/tutorials/making-a-pencil-drawing-from-a-photo....
Here you can see a little example:

Creates a picture which is a duplication of the current picture upscaled and blured as background,
and the current picture itself with a border and shadow around it as foreground

Example:
Original picture :
Result picture :

The second version of the script add a dialog box that let you modify the blur ratio as well as the shadow ratio.
I also added 2 toggle button to control the de-saturation of the fore/background.

Based on the set edge, pixel ammount, color and brightness, this script-fu generates a layer that looks techno.

Here is an example of what it makes...

You can find it when you create the image window...
Script-Fu -> Render -> Tech

(Note: This is my first Script-Fu)

A script-fu to add to a photo a realistic effect of mist and fog. After treatment, you can delete excess mist by painting with a dark color and a soft brush on the layer's masks, or by adjusting the opacity of "Mist" and "Clouds" layers. You'll find this script in "Script-Fu/Effects/Harry's mist".
Comments are welcome, and I will consider any changes that you request.

The script use some code from Dodge burn is a script for The GIMP
by Harry Phillips
The script is located in " / Script-Fu / Enhance / HDR Fake Effect..."

Puts 2 borders around the image. The outside border is a Gausian blur of the image itself, the inner border is a colour.

This script has 4 options:

1. Border colour, pick the colour of the inner border.
2. Border size, the width of the colour border.
3. Blur amount, the amount of blur applied to the border.
4. Blur border size, the width of the blur border

UPDATE (26 Jul 2008): The script now checks to see if the image is big enough to fit the borders.

This script turns a photo into an image that looks like a sketch. Clicking on the photos below will take you to larger versions.
