Looking for another technique

Going back to the desktop wallpaper I created for myself: The wallpaper utilises only two colours, one for the background and one for any graphics/objects on the background, basically a "black & white" background but using two differant colours instead of b & w.

I would like to take a photographic image and convert the image to only two colours ... with the subject of the photograph (say, a person) in the foreground colour and the rest in the background colour, effectively making a silouette(sp) of the photo's subject.

So basically I need to rubber band the subject of the photograph (I would assume some method of masking would be best here) and convert the photo to only the two colours I am using, but my fiddling around has so far not gotten me anywhere.

Any tips? Sorry, I am an absolute novice with image editing/manipulation. I am reading some of the online gimp guides/manuals but that only gets me so far!

Thanks!

I'm pretty sure there are some projects like that in the book "Grokking the Gimp", at http://gimp-savvy.com/, as well as various ways of selecting the foreground object.

The straightforward way is to use your favorite technique to make the selection around the subject (I usually end up making a Bezier path then doing Path to Selection, but sometimes you can use the magic wand or other selection tools, depending on the image), use the bucket fill tool to fill with the foreground color, do Selection->Invert, and use bucket fill to fill with the background color.

Mark,

Have you tried using the threshold tool (rightclick->image->colors->threshold)? That will break the photo down into black and white based on the levels. So long as the object I want is the focus of the image is usually does pretty well. You can then use fuzzy select to change the colors to whatever you want.

Regards, Andrew

Thanks Andrew. I gave this a shot but it does not seem to work ... I think maybe because the foreground and background colours are not distinct enough. I think I will look at using bezier curves ... got some reading to do!
