Focus Stacking for Product Photography

From the B&H YouTube Channel:

What is focus stacking, and how does it work? In this product photography tutorial, Jake and Bobby show you how taking and processing multiple images at different focus distances can produce a greater depth of field than a single image is capable of. The final effect being the full image in sharp focus.

Note from Sean: I often use focus stacking when photographing flowers and highly recommend giving the technique a try when photographing small [motionless] objects.
