These days, everyone has a high-quality digital camera right in their pocket. Plus, right on your computer you have photography-editing software like Photoshop that just a few years ago would've been considered professional grade.
Together, they've made it really easy to doctor your photos. Magazines do it with their cover models, and maybe you've used Photoshop to take the red out of your eyes or, for fun, stuck your son's head on a bodybuilder's body.
So, photoshopping is a 21st century thing, right? As it turns out, people have been doctoring photographs for centuries. Case in point: A photograph of Ulysses S. Grant, the 18th president of the United States.
Prior to his presidency, Grant was a Civil War hero. As the Commanding General of the Union Army, he and his troops defeated the Confederacy.
He's one of the first presidents to be photographed and, in fact, there are several of him taken of him in the mid 1860s, including the one above. Except, can you tell what's wrong with the photo?
