This is the top cover of a bamboo steamer. I tried a different procedure to do the focus stacking. I used Rob Marshall's recommendation to use the script method available in Photoshop CS5. This was made using 6 images stacked. The actual width of the bamboo material is about 1/2 inch. Thank you very much for viewing.
