Have you heard of the Google Art Project? Google has been taking extremely high-resolution images of famous works of art from around the world and posting them online. Not only can you see highly detailed images of famous paintings and other works of art, but you can even take a virtual tour of galleries like the Metropolitan Museum of Art in New York, the National Gallery in London, the Uffizi in Florence, the Palace of Versailles, and more!
To use the site, select a museum from the homepage and then either choose "Explore the Museum" or "View Artwork". Once you are in the main site, use the drop-down menus or the side info bar to navigate between artwork and museums. You can even create and share your own collections online!
If you are interested in showing artwork to your students in class, using Google Art Project to display images of paintings can allow you to zoom in to see the tiniest details. You can zoom in so close, in fact, that you can actually see more detail than you could see in a museum (where guards would undoubtedly stop you from getting too close!) Another fun class activity would be to take your students on a Street View tour of one of these famous museums.
Google Art Project can allow you to dig in to artwork and discover things you might not otherwise see if you were looking at an image of art in a book or magazine. Check it out!
