From Photojojo I learned about this article in the June Scientific American. Some pretty high-end stuff, but this is a very important skill for us and our students to learn.
It used to be that only professional photographers had the ability to "doctor" photos. But now, thanks to Photoshop and all the other image-editing software, ANYONE can fake a photo AND put that photo on a webpage, or attach it to an email.
Wouldn't this be a great way to talk about propaganda? Or political campaigns?
Our students, and, unfortunately, many adults, assume that everything they see on the internet is true, especially if it's a photograph. This article will be a real eye-opener for many!
