Is there a way to leave an image with only black pixels in photoshop?

Question

Adobe Photoshop

Is there any way to leave an image with only black pixels, for example? There is an image of a fence and you need to remove the background and leave only this fence. The "magic eraser" is not effective in this situation, as it is a patterned and therefore complex fence. And so I thought, maybe there is such a function or a method based on the available tools in Photoshop, which allows you to leave only those pixel colors in the image that you prefer?

Answer 1

Copy the layer, set it to a new brightness threshold, invert it, paste it as a mask on the original layer.

Answer 2

In such cases, usually only hands can achieve a quality result. As an option selection through the Pen. Long, tedious, but effective.
