Cokin NUANCES Extreme Full ND Filter Kit - P-Series (M)

Yes, you can stack filters in a P-Series holder, though stacking multiple ND filters can lead to vignetting or increased reflections. It is recommended to use one filter at a time for the best image quality.

These are made from tempered optical glass, which provides superior scratch resistance and optical clarity compared to standard resin filters.

Yes, they will fit a 77mm lens as long as you use the appropriate Cokin P-Series 77mm adapter ring.

A 10-stop filter requires increasing your exposure time by a factor of 1024. Many smartphone apps are available to calculate these long exposure times automatically.

While the glass is tempered to be more resistant to drops and scratches than standard optical glass, it is still glass and should be handled with care to prevent breakage.

Ensure the filter is seated fully in the slot and use a piece of black gaffer tape or a dedicated light-blocking foam gasket to seal the gap between the holder and the lens.

Check the holder slots for accumulated sand, dust, or debris. Clean the slots and wipe the edges of the filter with a clean cloth.

Verify that your white balance is set correctly for the scene. While these filters are color-neutral, extreme long exposures can occasionally be affected by infrared light contamination.
