How do they achieve a shallow depth of field in bright sunshine? Neutral
density filters stacked in front of the lens?

Yes. Exactly that.
Some cameras have them in a filter wheel between the lens and the
image sensor, but they can be augmented by extra filters in front.


Such ingenuity just to **** up the picture.
