This B&W 30.5mm 090 Light Red Glass Filter is the classic filter for strong contrast in black and white and architectural photography. The white sides of buildings shine brightly; skies are darkened dramatically and clouds become more impressive. It is also excellent for spectacular landscape photographs that will be characterized by greatly improved vistas.
