LEE Filters LEE85 Neutral Density Grad Medium Filter Set

It means the filter gradually transitions from a neutral density (darkening) effect to clear. 'Medium' refers to the transition zone's length, which is neither too abrupt nor too soft, making it versatile for general landscape use. 'Neutral Density' indicates it darkens the scene without altering the colors.

The choice depends on the difference in exposure between your desired foreground and sky. A 1-stop (0.3 ND) is for mild differences, 2-stop (0.6 ND) for moderate differences, and 3-stop (0.9 ND) for significant differences in brightness. You'll adjust based on your scene's contrast.

No, these filters are specifically designed for the LEE85 filter holder system. They are not compatible with older LEE100 or other LEE filter systems.

Yes, graduated neutral density filters can be used for video to balance exposure in dynamic scenes, similar to photography. The medium transition is often suitable for video work.

Harder grad lines create a more defined transition, which is beneficial for modern cameras with smaller sensors. This helps to better match the filter's effect to the sensor's capture area and can result in a more natural-looking balance in high-contrast scenes.

The grip tab is a small protrusion designed to make it easier to insert, remove, and adjust the filter's position within the holder. It also helps to keep your fingers from touching the optical surface of the filter, reducing the chance of fingerprints.

Gently wipe the filter surface with a soft, lint-free microfiber cloth. For stubborn marks, use a lens cleaning solution specifically designed for optical glass, applied sparingly to the cloth, not directly to the filter. Always avoid abrasive materials.

Ensure the filter is clean and free of smudges. Verify that the filter is properly seated in the holder. If the issue persists, try a different filter from the set to isolate the problem.

Experiment with the positioning of the graduated line within the frame. For very precise placement, practice on scenes with clear horizon lines. Ensure the correct filter holder is being used.

Utilize the integrated grip tab when handling and positioning the filter. Clean the filter gently with a microfiber cloth after each use if smudges occur.

Confirm that you are using the LEE85 filter holder, as these filters are specific to that system. Ensure the filter is being inserted correctly into the designated slots.
