Color reversal is a photographic technique that inverts the colors of an image, creating a negative effect. This process transforms bright colors into their complementary shades, resulting in a visually striking representation. For example, blue becomes orange, and green turns red. This technique is commonly used in film photography, particularly with slide film, which captures images in a way that can be projected directly. Color reversal can also be applied digitally through software, allowing photographers and artists to explore creative possibilities and enhance visual storytelling.
