What does Threshold do in Photoshop?

Answer 1

The Threshold adjustment in Photoshop converts an image to a binary image by setting a specific brightness level. Pixels lighter than the threshold value become white, while those darker become black, effectively creating a high-contrast image. This tool is useful for creating stark black-and-white effects, enhancing details, or preparing images for printing or vectorization. It allows users to adjust the threshold level to achieve the desired contrast and detail.
