I just realized that I haven't posted a Creative Commons photo in a long time. So, here is one :-)
About this photo:
I took this photo at the University of Pennsylvania Museum of Archaeology & Anthropology. This is an one example of their Islamic Art pieces. The lighting in the museum was very low, so the photo lacks a little clarity.
About the process:
Auto-levels/Auto-contrast in Photoshop.
About the License:
THIS PHOTO CANNOT BE USED FOR COMMERCIAL VENTURES (It's not my rule; it's a stipulation set forth by the museum). Other than that, you can use the image as you like. Please leave my name intact or otherwise post credit in relation to the photo. Links to my website are also appreciated. Thanks!
