Horizontal, black and white photos are custom framed in vertical mouldings with super long matboards. Just goes to show - don't let the orientation of the art determine where it will and won't fit. Anything's possible with custom framing!
This long hallway of floor to ceiling windows is stunning. We had custom frames/mattes made and filled them with black and white family photos. I love how it turned out and fully intend to use this idea in other projects.
