The DIFFUSER No1 is a creative filter in the HOYA's soft filter line-up that offers a unique kind of soft effect through creating an overall very slight unsharpness in the photo, softening the highlights and removing edge sharpness without reducing the contrast.
The surface of the HOYA DIFFUSER No1 has an irregularly uneven pattern achieved by roughening the glass surface through spraying hydrogen fluoride using a special masking plate.

Using the HOYA DIFFUSER No1 is an excellent opportunity to try out a new soft-effect style. The filter especially excels in portrait for softening skin tones and commercial photography, but can be used in video production too according to the creator's intentions.
