## Long description

lee filters Sky Blue 4 Hard is a 100 × 150 mm graduated resin filter with a hard (medium-hard) transition that combines a clear lower half and a coloured upper half. Designed for landscape and outdoor photography, the Sky Blue 4 adds a natural blue tint to skies while helping to balance exposure between bright skies and darker foregrounds. The 150 mm length allows vertical adjustment in a compatible holder; the 2 mm thickness ensures stable handling.
Advantages
The Sky Blue 4 Hard provides a hard-edge graduated transition suitable for scenes with a distinct horizon, preserving highlight detail in bright skies while introducing controlled blue colouring. Its resin construction and standard 100 × 150 mm size make it compatible with Lee-style filter holders and easy to position for precise blending. The medium-hard transition is a compromise between soft and very hard edges, offering predictable placement with many lenses.
Suitable for
Landscape photography with a distinct horizon
Outdoor scenes where sky and foreground exposure need balancing
Adding a natural blue tint to skies for creative colour grading in-camera
Key specifications

Model: Sky Blue 4 Hard (medium-hard transition)
Material: Resin
Size: 100 × 150 mm
Thickness: 2 mm
Compatible with: Lee-style filter holders
EAN: 619465016848
How to use
Place the filter in a compatible holder and slide it vertically to align the coloured transition with the horizon or the area where you want the blue tint. Use the hard (medium-hard) edge for scenes with a clear horizon line or distinct separation between sky and foreground. Meter the scene with the filter in place or bracket exposures to ensure retained highlight detail; adjust filter position to control the strength and placement of the blue effect.
Usage recommendations
For wide-angle lenses where the sky covers a large portion of the frame, check the transition placement carefully; the medium-hard edge gives more defined separation than a soft edge but can be positioned to avoid abrupt lines. Store the resin filter flat and clean with a soft cloth and mild cleaner to prevent scratches and preserve colour accuracy.
