I am a big fan of Abelardo Morell and some of his ideas were the inspiration for my Reflactions project. One thing that I saw back in 2009 on the BBC's excellent Genius of Photography series was how Abelardo used a room as a giant Camera Obscura. He does this by covering up all the windows with black paper/bin sacks and then creating a small opening in the middle of one that projects the view from the window on to the opposite walls. Last week the National Geographic released a video on the process, you can check it out below:
