Dreamy fog effect.

The HOYA Fog No 0.5 features a frosted surface that gently covers the entire image, creating a pleasant dreamy fog effect. Compared to other soft filters from HOYA, objects in the photograph remain sharp and contrasting.

The effect can vary by changing the aperture of the lens. There are two HOYA Fog filters, Fog No 0.5 and Fog No 1. Both can be used together to create a result similar to dense fog.

The HOYA Fog No 0.5 filter uses special slotted glass to achieve the effect. A piece of this glass is laminated together with a clear optical element, giving it a special sandwich structure that creates the fog effect.

The soft effect of Fog No 0.5 enhances the bright areas in the image, making them appear as glowing objects. It is highly recommended for night photography. Using this effect in landscape settings can allow the photographer to create a mythical atmosphere akin to a fantasy story.
