“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”
Ansel Adams, from the introduction to The Negative - The New Ansel Adams Photography Series / Book 2
I have a ton of examples of shooting the ground glass images on my site linked below. It is not what you are asking for. You may want to get a Lensbaby or tilt/shift lens to manipulate the DOF on a camera of that type and size.
