You can make it yourself. Look for a black and white hexagonal pattern in Google Image.

You can add some gradient in the hexagonal shapes by doing a soft selection and filling it with black. (selection > modify > deather).

Then you put it in a seperate layer and use the soft light blending mode for example. In combination with some blur filter.

Tip: first search for a reference photo and try to copy the effect
