Lichen Colonies on Maple Tree in Neighborhood - Texture

Yesterday I was walking in the neighborhood and foiund some lichen colonies on a maple tree.  I was intrigued because there was a lot of  a golden color there.  I was disappointed that the images I took were not as sharp as I had hoped. Should have done a playback instead of relying on the LED screen. Oh well, I hope to get back and try again when there is more sunshine.  Sometimes you can salvage an image using apps.   Taken with Camera+. Post processing done with PSE 11.  Left image has just increase in highlights & mid-tones, then sharpened a lot to give texture.
 I had taken the image at an angle rather than landscape. changed mode to square, and tried to do macro which uses digital zoom--not as good as optical zoom.  The right image I used a "Saturated Film" filter in PSE 11.  You can even see the green moss in the cracks if you are able to enlarge the image.
