I recently came across pictures of this living room on Apartment Therapy and fell in love with the large photograph over the couch:
Pictures from "Genevieve and Maxwell's Mid Century Perch" House Tour on Apartment Therapy
I think I may steal this idea for a wall in our kitchen/ dining area... currently some artwork that I painted is hung there, but don't really love it and have been trying to decide the right replacement. I can't afford a professional piece of art like shown above (House Tour comments indicate the photo is by Kelly Barrie), but this would be great (and even more meaningful!) to implement with a personal photo.
I think what would keep the same feel is to do something abstract. It could be fun to shake up a champagne bottle and see what shots you get out of it. Last summer a friend's wedding had sparklers as the bride and groom exited and they looked great in pictures - a close-up of the sparks would also make for a really neat shot.
