An unbelievable resource debuted February 1, 2011: Google Art Project – www.googleartproject.com. Fabulous works from 17 (so far) museums worldwide are available in incredibly high resolution. Besides viewing the artwork, you can explore the museums via virtual tours. You can create and share your own collections. Here’s a link to the visitor’s guide: www.googleartproject.com/c/faq.
The accompanying images show the amazing amount of detail these high-resolution images capture. And – you can see in the frame of reference in the lower right that I’m framed in only about half of the way. Here’s a link to the actual image you see above: http://www.googleartproject.com/museums/tate/no-woman-no-cry
