i see what you are saying jim68134 ... but even 100 + years ago photographers manipulated images and altered scenes. take post cards for example - if you look at post cards from the turn of the last century even into the 1920-30s, you will see evidence this - people walking on a boardwalk or down a street -people walking a baby stroller &c. they were "dropped into the scene" - smoke in smokestacks (= progress) and that was painted in as well, and then there were the photographers and retouchers who 'swapped heads' in portraits. if you haven't seen the movie "photographing fairies" .. ( i know it is fiction but ... ) you get to see an edwardian era portait photographer doing things like that ...

the expression " believe none of what you hear and none of what you see " has been around for a long long time
