I found these photos from a Russian photographer called Sergey Larenkov. He photoshops the old with the new, more specifically he looked at world war 2 photos and matched up the locations with todays photos to see how the place has changed. I think I could maybe do something similar in Cardiff with this Facebook page which has been collecting old photos of Cardiff. You could hold up you phone and get a half image of old Cardiff and super impose it over the current day Cardiff on your phone… easier said than done I’m sure.
More recent photos of a similiar style, ones taken in Ukraine.
