Meet the GIMP #93: Isolation!

In this episode I try to isolate a subject from the background.

There are a lot of ways to do this - I chose to make a layer mask with the threshold tool. Selecting with the path tool is an other option - see the comments to this post.

To get rid of the artificial look I feathered (blurred) the edge of the mask a bit. This gives a soft edge.

The subject of this image is the logo of the Weltladen in Bremen. This is a shop with fair trade products. In the past these products were often bad in quality and high in price, but this has changed. Now the goal of a lot of fair trade organisations is to get the producers to good quality for a competitive price and make them fit for competing in the regular markets. By going mostly organic they can get more money for the products. We buy there all our chocolate (in the box with a bulk discount ) , wine, orange and other juices, rice and even a honey from southern Chile. Philippe considers this type of honey as the best from Chile and recommended mixing it with yoghurt. Exellent!
