I had to try my hand at the filter challenge too, especially after being inspired by Hilary's beautiful layout this morning. I had previously rendered this photo in B&W but wanted to try something else as well. I will post the original picture in the forum challenge thread.
One thing I did differently was once I reached the stage of changing it to B&W and inverting it, I added a sepia tint. I also used a brush to lighten and give the sky some texture. I used a colored pencil filter on the top layer, then reduced the opacity of the top 2 layers. I really like the look of the trees with this technique! I turned it into a card and printed it on watercolor paper, and then I'll mount it on brown cardstock.
No scrapping supplies used here - just pure filter!
