The Heliopan Hasselblad Bay 60 Light Yellow Filter (#5) enhances contrast in black and white photography, refining images that appear flat. Its moderate yellow tint improves tonal separation without overpowering the scene. Crafted with a slim black anodized brass mount, this filter minimizes vignetting even on wide-angle lenses. Ideal for photographers seeking subtle but effective contrast enhancement in their black and white film work.
