To Photoshop, or not to Photoshop...

The modern debate over the Adobe photo editing software, Photoshop, is whether or not to use it for body shaping.  Many of us dismiss the photos seen in the hottest magazines or in advertisements because it is common for them to be Photoshoped drastically.  Some people are worried that these images of size 0 and 1 women is adding to the pressure of young girls.  The concept is that these unrealistically slim models are being broadcast as "the norm" and creating self-image issues for vulnerable young teenage girls, leading to eating disorders and related psychological problems.
There has been a bill introduced in some European countries such as Norway, France and England mandating that digitally altered photos be labeled as such.  A professor and Doctoral student at Dartmouth University have used this concept and debate over Photoshop as inspiration for a computer program that measures the altered state of an image.  These two, Dr. Farid, and Eric Kee, have developed the software tool to measures just how much an image has been changed on a scale of 1 to 5.  This algorithm developed by Farid and Kee statistically measures how much the photo of one's face and body has been altered.  Interestingly enough, most of the pictures they used to create the algorithm were taken from websites of "professional Photoshopers" showing off their abilities.  The program simulates how a person would decide if an image has been altered.  In order to do this, they used many people to compare before-and-after Photoshoped images and rank them on a 1 to 5 scale.  These ratings the people gave images were used to train the software so it can accurately decide what altered-state rank to give the photo.
Potentially, either the labeling of altered pictures or this software program, could have drastic implications on society and the social pressures to look like a model.  However, some argue that there is already a decrease in Photoshop usage in the fashion and magazine industry.  One editor commented that it is alright to do simple touch-ups or changes, but mentioned, "Readers arent' fooled if you really sculpt the images.  If you're a good editor, you don't go too far these days.  If you give someone a face-lift, you're a fool."  So, it is up to you to decide, is it a good idea to label images? What could be the impact of this photo-alteration detection technology on society?
