9. In the dialog ox that opens, adjust the mask radius and percent black that you want in your sketch, I have shown the settings I used in the picture below. Play with the sliders to study their effects.

10. Now to make a decorative border for our picture. Click on Script-Fu->Decor->Fuzzy Border

*img503.imageshack.us/img503/1846/fig14fp0.th.jpg

I just saw that the colour of the border was white, that's the one I wanted for this picture, so I leave it as it is. And click ok

Very nice tutorial.But i can do it in Photoshop without using filters
through vector painting.

 

[NucleusKore]

Thank you
This works good if the background is plain, as in photographs shot in a studio. Too much detail in the background may mess up the work

Thanks, you may also skip step 2 and see what happens, gives a colour sketch

I see, I am not a professional, been using GIMP for a year now. I have seen many pages of tutorials on this forum for Adobe Photoshop. Nice, but how many people actually own the original software. Not many I'm sure. But then the pirate version is so easily available
I hope to be writing now and then on my experiences with the GIMP, lets see how far I go.
