Today it seems like doctoring photos is as common as 'Saying Cheese'. For a while, it was only popular with snapshots of the rich and famous. Now, everyday people are altering reality. Is it technology at its best, or are we faking memories instead of making them? When Theresa Newman's father passed away from Oral Cancer, she was devastated. "He was just always there for me," she recalls. To make things worse - she realized too late that she didn't have a single photo of the two of them together. So she took a picture of her dad and his friend to a photo retoucher and made an unusual request. She asked, "I have a picture of my dad and Katie. I would like to take Katie out of the picture and put me in. Can you do that?'" About a week later, Theresa had a brand new treasure of her past. "I totally lost it because it looks exactly like we actually sat together for the picture," she explains. Photo editing is big business. People pay professionals anywhere from $20-150 per hour to perfect portraits. But these days, even amateurs can play. Photo editing software is cheaper and easier to use than ever. Experts say you can do something as simple as removing red-eye...to much more extreme! Chris Johnson is a Professor of Photography at the California College of the Arts. He says, "Well, the most extreme kind of things are when you actually have the impulse to remove people who were at events so that, at least as far as the photograph is concerned, they no longer are there." Like after people break up. Of course, like in Theresa's case, you can also add people in. Professor Johnson remembers a wedding he went to a few years ago. One of the bride's cousins couldn't attend. "So we left a space for him in the photograph of his cousins. I scanned him and dropped him in," Johnson recalls. The resulting photo is so realistic… Chris says today many family members think they remember seeing him at the wedding. That is exactly what worries Family Psychologist Alan Entin. He uses photos as a tool in therapy sessions. He says this kind of casual editing may seem harmless, but it's not. "When you start to alter family photographs, you're really altering family history and the future," Entin says. He considers every photograph to be an important record of who we are, and where we've been -- and insists they shouldn't be tampered with. "If we alter them, the photographs become meaningless because they're not reality," Entin warns. But Theresa sees things differently. She says the technology has offered her one last precious memory of her father that she can look at and cherish forever. "Even though I know I wasn't there, it looks like I was and it means the world to me," she explains. It's not just families playing with pictures. If someone can't make a class photo or sports team shot…players or classmates can always be added in at a later date. Advanced photo editing tools can still cost several hundred dollars. You can get consumer versions for about a hundred dollars or less.
