OPF 550-L
OPF (Optical Preset Filter) is a camera lens filter designed to layer sensation into photography by controlling specific wavelengths of light, allowing balance, atmosphere, and a gentle sense of depth to emerge in the image.
With an optical design targeting wavelengths around 550 nanometers, OPF organizes the characteristics of green light, stabilizing color balance while subtly shaping light edges and overall transparency across the frame.
Two diffusion types are available: S / L, each offering a different level of light spread. L (Light) introduces a more expressive diffusion, creating clearer changes in highlight bloom and a smoother, more expansive spread of light, while maintaining a natural and well-balanced look.
As a BASE filter within the Layer-X system, OPF 550-L is designed for everyday use—a reference filter that preserves balance while gently widening the range of expression that can be layered on top.
