As a youth I wavered between absolute non belief in ghosts and scared out of my wits that they existed. Now, as a senior adult, I no longer fear ghosts but believe they exist. I have had multiple “ghost experiences” throughout my life. These have convinced me that the vast majority of ghosts are benign. They are trapped in transition with unfinished business.
A neighbor had a whimsical lamp that played friendly ghosts on the side of his house. I took this photo with my Canon with an 18-55 mm lens at 55mm. 1/5 second exposure at ISO 1600.
Basic processing iPad Photo app. Applied noir filter, and adjusted contrast to blacken the house.
