if you had a photo

or get your picture taken with a large clock set in the 1880s

If you brought a camera with you when you went time travelling. Would people believe that the pictures you took are real?

It would be very easy..I would buy a movie camera and film and take a friend with me back to the 1920s and film as much as i could around London at that time with me doing the commentary and of course showing myself with modern day technology..I phone..laptop..etc etc
Obviously i would have to include a girl from that time period, ideally holding a newspaper

so it would be really hard prove that you time traveled. It would be easier to build the time machine than to convince a sceptic that you went back in time.
