The first one with the light streaming through the trees?? Love this....I have a collection of pastoral and tree forest pictures. Love this.

What a creative soul you are....seriously. This idea is a great idea!!

There used to be a "posterize" edit in Picassa - I don't know if another software would have it...you could try using that and playing with the controls to see what happens. I really like what you've done though and can't wait to see what it is you are trying to achieve.

I'm a fan.
