Soft focus is a photography technique that creates a dreamy, blurred effect by slightly defocusing the lens. This method softens sharp edges and reduces contrast, resulting in a more flattering and ethereal appearance. It is often used in portrait photography to enhance the subject's features and create a romantic atmosphere. In addition to photography, soft focus can also be applied in film and video production. By using special filters or post-production techniques, filmmakers can achieve a similar effect, adding a layer of visual softness to scenes. This technique is commonly associated with genres like romantic films and dream sequences.
