This image has a great feeling of depth. The door knob on the right through the door, along the pathway, the street and the house across the street are all elements of this deep 3D impression. I used a single raw photograph that I developed for the outside first and saved as a tif file. Then I used the same raw file that I developed for the inside of the house. The second image I put as a layer on top of the tif file and created and painted a mask that made the outside of the tif file (outside) visible.
Enjoy and try this easy to use technique.
