如何使專案影片的影片變暗

When it comes to video production, one frequently used technique is to darken specific areas of the footage. This process can be done for several reasons, such as to create a mood or atmosphere, draw focus to a particular part of the screen, or help hide imperfections.

By reducing the exposure and increasing the contrast, shadows are intensified, and highlights are minimized, giving the footage a more ominous and foreboding feel. This process can be particularly effective in horror movies or thrillers, where the audience is meant to feel on edge. For your project video, you must learn this technique with the detailed guides below.
