What is this technique called in web design?

Question

Design

Hello!
I saw on one site the following processing of a photo:

I mean the effect of strokes at the bottom of it. A sort of transition to the next section of the landing page.
What is the name of this thing or how can it be rendered in Photoshop?
Thanks for the answer!

Answer 1

I don’t know, I would just take the finished brush from Photoshop, set the desired parameters and paint.

Answer 2

A mask is made on the layer with the picture and painted on it with brushes. Black is absolute transparency, white is absolute opacity, grayscale is transparency.
