Lee Filters

Lee Filters Sky Blue Graduated Soft #3 Filter 4x6" Resin

SKU CH-AJM8-N8TAT

A 4x6-inch resin graduated filter that adds a soft-edged sky blue tint to the upper frame for landscape and seascape colour enhancement

  • Softer blue tone than Real Blue or Twilight Blue series
  • Sky Blue #3 strength adds subtle cooling to skies or water
  • Soft-edge graduation blends colour smoothly into clear area
  • 4x6 inch resin construction fits standard filter holders
  • Medium cooling filter series ranges from #1 mildest to #5 strongest

Purpose and Audience

This Lee Filters Sky Blue Graduated Soft #3 filter adds a gentle sky-blue tone to the upper part of a scene. Landscape and seascape photographers use it to deepen pale skies or enhance water colour without affecting the foreground. The 4x6 inch resin sheet fits standard filter holders for creative control in bright conditions.

Who It Suits and Who It Does Not

The soft-edge graduation blends smoothly into the frame, making it ideal for uneven horizons such as hills, trees or buildings. Photographers needing a sharp, abrupt transition for flat horizons will not find that style here. Buyers who want a stronger or weaker blue density should choose a different grade in the same series.

Key Specification

The filter is a Sky Blue Graduated Soft #3 made from optical resin in a 4x6 inch format. It sits midway in a five-strength cooling series, providing a moderate blue cast with a feathered edge for natural-looking results.

  • Sky Blue #3 strength adds subtle cooling to skies or water
  • Soft-edge graduation blends colour smoothly into clear area

Questions about this item

What filter holder system is required to use this 4x6" resin filter?

This filter measures 4x6 inches and is designed for the Lee Filters holder system that accepts that size.

How does the soft-edge graduation interact with a lens that has a rotating front element?

The soft graduation provides a gradual transition, so rotating the filter in its holder adjusts the horizon line without a hard edge appearing in the frame.

How can I verify the #3 strength is producing the intended cooling effect on my sky?

Compare a test shot with the filter against one without; the sky should show a noticeably stronger blue tone than the Sky Blue 1 or 2 filters would give.
