H&Y Filters 100 x 100mm K-Series Filter
- Reduces the appearance of light pollution in images or video that include the night sky and illumination from artificial light sources
- For cameras with daylight film installed, or a digital camera system with its daylight white balance setting selected
- Absorbs the yellow light from sodium-vapor lamps, mercury-vapor lamps, or low Color Rendering Index LED’s, common light sources within urban areas
- Enhances the visibility of astronomical objects, and where they appear, artificial light sources are more clearly defined with less glare and improved contrast
- 2x filter factor reduces exposure by 1 stop
- Constructed from optical glass for clarity
- Each glass surface includes eight layers of anti-reflection coatings to prevent internal ghosting and reflections as well as an anti-smear, nano coating for an improved beading effect when in contact with water or oil for greater cleaning efficiency
- Filter pouch for storage and transport, as well as a microfiber cleaning cloth for filter maintenance
H&Y Filters 100 x 100mm Quick Release Magnetic Filter Frame
- Pre-installed along the edges of the included 100 x 100mm K-Series Filter for use within an H&Y Filters 100mm K-Series Filter Holder that is configured with a pair of magnetic filter slots
- Allows 100 x 100mm K-Series Filter to be magnetically stacked in front of a camera lens along with other filters that have a Quick Release Magnetic Filter Frame installed, instead of inserted only within one of a specific number of filter holder slots
- Helps allow the user to determine the number of filters to be applied when using a 100mm K-Series Filter Holder, all of which can be quickly installed, repositioned, or switched with a different filter needed for other subjects or changing lighting conditions
- Reinforces the edges of the 100 x 100mm K-Series Filter, enhancing that filter’s rigidity and promoting sharp results by helping to ensure that the filter remains flat
- Front-facing center finder rulers on side sections of this Quick Release Magnetic Filter Frame help enable precise positioning of the 100 x 100mm filter it is installed on, relative to another filter that 100 x 100mm is stacked on
