NightScope is a single Photoshop-compatible plug-in filter for adding a basic "night-vision" effect to your digital photographs and/or 2D and 3D computer-generated images. It first removes all colour from the picture and gives a very slight blur to indicate the film is trying hard to focus in a low-light situation. Then you can choose to add grain either keeping it B&W or mixing separate red, green and blue channels to vary the effect. You can also produce a strong overall colour cast using the RGB sliders provided. Works best with dark night-time photographs that have minimal areas of bright background elements in the scene.
