Overview

The Heliopan 1011 Yellow-Green Filter is a black-and-white contrast filter designed to deliver natural tonal separation and accurate grayscale rendering in monochrome photography. It is especially effective for landscape and outdoor work, where it brightens green foliage while gently darkening blue tones and slightly reducing reds to create balanced contrast and improved depth.

Manufactured in Germany using premium SCHOTT optical glass, it features a precision-machined brass slim mount with front threads for stacking accessories or attaching a lens cap. The optical surfaces are multi-coated to reduce reflections and improve resistance to water, dust, and general environmental wear, making it reliable for field use.
