Stiching Long FL Tiles for Shallow DOF 1905 Style
 

Shallow DOF can be created with stitching long FL tiles, even with crop
cameras and thus get the large format look of the early 20th century.
The latest iteration of this method is called "Brenizer". The trick is
to keep live picture elements in one or possible two of the central
tiles. You need at least two, but nine will give you a more dramatic
effect. You can use PS Photomerge for stitching.
