"There is only you and your camera. The limitations in your photography are in yourself, for what we see is what we are."

72dpi with unused space filled with black canvas.
The attached pdf shows how to do this in Photoshop CC and photoshop Elements - details may vary slightly with earlier versions of photoshop.
