This 72mm Blue Enhancer (Intensifier) Filter from Hoya is designed to enhance blue colours of the spectrum. When a circular polarising filter alone cannot enhance enough of the blue colours, because of a cloudy sky, combine the Blue Enhancer and a Circular Polarising filter together and it will intensify the colours and increase the contrast of the image.
The Blue Enhancing filter has a filter factor of 2.5, so you should increase your exposure by 1 and 1/3 of a stop to compensate. Transmission of light passes easier through the filter, because of a single type of coating, which has been placed on both sides of the glass; reducing reflections off the surface of the filter. The ring is made of aluminium adding strength and protection to the lens while is it screwed on.
- Single coating on both sides of the glass for better light transmission
- Enhances blue colours
- Aluminium ring for durability
- Front threads allow filter stacking
