I found a very interesting article about ideals now and then, with art GIF's created by Lauren Wade:
"To shed light to the unrealistic body ideals created by virtual scalpels, photo editor Lauren Wade has taken her Photoshop tools to famous paintings that feature iconic images of female beauty. By perking up breasts, pulling in waists, creating thigh gaps and smoothing out blemishes, Wade shows just how extreme Photoshop culture has become."
Read the article and see more pictures here.
This painting plays a central part in Jostein Gaarder's book "Maya". I love his books, and when he combines a good story with a little bit of art history it gets even better!
