First I took the original image from a garden magazine that sold wall hangings. The original image was 411 x 310. This is important becauses unlike leonardo, every image used to make a terrain in bryce will be made square. To get the right scale ratio the terrain will have to be resized once it is made.

The image was small so I doubled it in paintshop and applied a gausian blur of 1 to take off the sharp edges and give me more room to work. Here is the finished color image.
