Tunnel Ghost Busted

I had some friends over for dinner last weekend. What was supposed to be a relaxing Sunday dinner suddenly turned cold with fear. A friend, senior tunnel engineer, was flipping through his phone pictures when he suddenly spotted a picture of his worksite with ghost in the background, a whitish girl on the tunnel wall. His face turned white and mood subdued when he showed the picture to us.
I couldn't believe it. But the fear on my friend's face and the intensity with which he refused to accept any of my scientific explanations of possible manipulation of the picture soon gave me goosebumps. His phone doesn't have internet connection to download the picture from elsewhere and he was confident that it was the picture of his worksite and he took the shot himself.
He grew restless and paranoid. He sweared he will never enter the tunnel again. He recalled how his camera didn't work when he took picture of himself. He took out his phone from time to time and looked at the creepy picture, and worse made us look at it. After a while I could look at this picture no more. It was as if the girl would look at me anytime. I even asked him if there's some dirty bloody secret inside his tunnel that's now coming out in the form of spirit.

Rest of the evening went in talking about all sorts of ghost stories. And when the dinner was done one of my guests, the youngest among us, couldn't go home. He is also an engineer but not in tunnel. He doesn't have a family yet and all his roommates were not home that night. He easily accepted my offer to sleep on my couch. (Talking about critical blogger Dawa Knight, lol)

Look Closely, you don't wanna miss the ghost!

Next Day: (I heard) The senior engineer friend freaked everybody outside the tunnel at his worksite. He approached his boss with the picture and it had the same effect on them as well. Their office gathered all IT experts to study the picture, and finally they could disintegrate the picture of the girl from the picture of the tunnel it was photoshopped to. They also managed to photoshop it onto the tunnel of other site and post it to them.

The question remains: It was a flawlessly done photoshop work, who did it? how it came to his phone? Why would anyone do it? The answer same from his wife who spent the next day investigating the same. She found out their kids have played with a camera app called Camera360 which has many options which includes Ghost Mode. Ha ha ha kids can scare the hell outta adults with technology.
