Ghost Catcher by Code Pumpkin

Looking for a ghost? This app allows you to take or choose a photo and that photo is then transformed into a gray scale image with an eerie green filter to help you see if a ghost is in the photo.

This already sounds like a barrel of fun doesn't it? But hold on, there is more...

This app is really intended as a prank app to scare the heck out of people. There is a unnamed setting on the toolbar that uncovers a hidden switch. When the switch is turned on all subsequent photos taken or chosen will add a series of random ghostly images to the photo. The images are designed to be subtle yet frightening, so sometimes you might not see it right away, but once seen it will scare even the most hardened skeptic.

For best results of your ghostly images, take or choose a photo that shows distance (like down a hallway, across a room, down the street, etc) and take or choose a photo that is in a slightly darker setting.

All the ghostly images you create can be saved to your photo library too.

Enjoy!
