Over thirty years ago I remember reading an article in a photography magazine which demonstrated a technique for getting extreme depth of field in a macro shot. The results which made such an impression on my teenage self that I'm recalling them now, were blades of grass in the foreground with an entire backyard in focus maybe 50 meters of depth of field. The setup was extremely homebrew, from what I remember combining large lenses threaded back to front, and the exposure was done over as many hours of daylight as were available.
The results looked like something from Honey I Shrunk the Kids which was a popular movie around that time. It didn't look like traditional macro photography. It looked like small things were giant things. In the same way tilt shifting makes giant things look small. To this date, I've never seen photos like these, and I'm wondering if anyone knows of a technique to create similar photos. Looking back at it, it seems like black magic given the lengths one must go through using stacking to achieve even a few millimeters of depth of field in extreme macro photography.
