Urth 82mm Hard Graduated ND8 Lens Filter Plus+

It means the filter has a sharp, defined line (hard gradation) that transitions from a darkened area (ND8, reducing light by 3 f-stops) to a clear area. It's designed for scenes with a clear horizon line.

Check the front of your lens for a filter thread size, usually indicated by a diameter symbol (ø) followed by a number (e.g., ø82mm). This filter requires an 82mm thread.

It depends on the size of your lens hood. Many standard hoods may need to be removed or a smaller, 'hooded' filter adapter might be required. Check for compatibility before purchasing.

It reduces the amount of light entering the lens by 3 stops in the filtered half of the image. This balances the exposure between a very bright sky and a darker foreground, preventing blown highlights and retaining detail.

Yes, graduated ND filters can be very useful for video to maintain a consistent exposure, especially for cinematic shots with a clear horizon.

The 'Plus+' designation typically refers to Urth's enhanced coating and glass quality, offering superior performance in terms of clarity, color neutrality, and durability.

Use a soft microfiber lens cloth. For tougher smudges, use a dedicated lens cleaning solution applied sparingly to the cloth, not directly to the filter. Avoid abrasive materials.

Ensure the filter is clean and properly aligned. The nano-coating helps with color neutrality, but heavy smudges can sometimes affect results. Verify camera white balance settings.

Check that you are using the correct filter size for your lens or adapter. Ensure the threads are clean and not cross-threaded. Gently try again with a straight alignment.

This can occur with wide-angle lenses. Try stopping down your aperture by one or two stops, or consider using a thinner profile filter if available for your lens.

This filter is best for scenes with defined horizons. For irregular or soft transitions (e.g., trees, clouds), consider a soft-edge graduated ND filter or digital post-processing.
