Color reversal is a photographic technique that involves inverting the colors of an image. This process transforms the original colors into their complementary hues, creating a striking visual effect. For example, bright red may turn into cyan, while green could become magenta. This technique is often used in artistic photography and graphic design to create unique and eye-catching visuals. In traditional film photography, color reversal was achieved using slide film, which produced positive images directly. In digital photography, software tools can replicate this effect by adjusting color channels. Color reversal can also be applied in printing and video editing to enhance creativity and explore new artistic expressions.
