have you ever seen a ghost in a photo or seen 1 in person? what was it like?

I've seen things (both in photographs and in real life) that I really have no explanation for. It could be a ghost, or it might not. I'm definitely open to the idea that what I'm seeing could be a ghost, but I can't prove it. And since I can't prove that it isn't a ghost either, then I'm left with something that can't be explained!

I remember a friend from college said she taken a photo with ghost with them. Im not really sure, she showed us the photo taken from her phone and it looks like a smoke that just passed by. I also seen this kind of story in television but i wasn't sure if it's true or not.

I have never seen a ghost in person but have seen photography of supposed ghosts. I am skeptical of any photos today with ghosts. With all the software out there it is easy to create one. Even photos from the past can be fakes. For example when cameras came around in the 1800's, the shutter would stay open for long period of time and people would have to sit still for quite some time. By accident, people would move and the resulting photo would be a ghost like effect. Some photographers took advantage of this and would purposely create these photos. But there are photo experts out there who say they can tell the fakes from the real thing.
