Filter set Lee Sky Grad FHSS 100mm size by lee filters — graduated neutral density filter set for 100mm holder

Lee Sky Grad FHSS 100mm filter set contains graduated colour filters designed for use with 100 × 150 mm holder systems. The set is intended to balance differing light levels within a scene by reducing or adding colour in part of the frame, for example to darken or introduce blue tones to the sky. Each filter is a half-colour, half-clear graduated filter with a transition zone and is made in a 2 mm resin format that fits the Lee 100 mm holder and allows vertical adjustment of the filter position.

Advantages

The set includes filters with different colour effects and transition types, enabling selective colour enhancement and controlled light reduction across the frame. Soft-edge and hard-edge graduations are available to suit wide-angle and longer lenses respectively. Filters are 100 × 150 mm, 2 mm thick, and compatible with Lee 100 mm holder systems, allowing accurate placement and repeatable results in landscape and architectural photography.

Suitable for

• Landscape photography to balance bright skies and darker foregrounds
• Architectural and on-location shooting where partial light control is needed
• Situations requiring subtle colour tinting of the sky or selective areas of the frame

Key specifications

• Format: 100 × 150 mm resin filters
• Thickness: 2 mm
• Compatibility: Lee 100 mm holder systems
• Filter types included: Sunset 2, Sky Blue 3 Grad Hard, Coral Stripe

How to use

Insert the chosen graduated filter into the Lee 100 mm holder and slide it vertically to position the transition zone across the horizon or the area you want to affect. Use the soft-edge filters for wide-angle compositions and the hard-edge Sky Blue 3 for normal to longer focal lengths. Combine exposures or adjust exposure settings as needed to retain highlight detail and achieve the desired balance between sky and foreground.

Usage recommendations

Use the Sunset 2 to enhance warm end-of-day tones, the Sky Blue 3 Grad Hard to add blue to dull skies without affecting the foreground, and the Coral Stripe to boost a narrow band of colour typically directly above the horizon. Avoid stacking multiple dense graduated filters when possible to prevent vignetting on wide-angle lenses.
