The difference between OPF 480, 550, and 650 lies in which wavelength range they affect, and how that changes the overall mood of an image. Each filter has a distinct direction in the way it shapes light.
OPF 480-C / S / L emphasizes clarity and transparency, creating a clean, crisp atmosphere. It works well for scenes such as morning light, highland landscapes, or dry winter air.
OPF 550-C / S / L produces soft, natural, and balanced light. It is less dependent on time of day or weather, making it an easy choice for everyday use.
OPF 650-C / L adds depth with a subtle warmth, creating a more dramatic tone. It is well suited for evening light or backlit scenes where you want light to linger with a sense of afterglow.
