Definitely real. Digital cams all have their own quirks on how they "interpret" the signals received. 99% of all the "paranormal" things you see on digital cameras are simply imaging defects. Digital cameras will continue to get better and have their place, but they aren't a true representation of what is out there. Even film has it's limitations, but it's more reliable, imho. Huge tradeoff in cost though, so no one is going back to film.
