The vibrant light programs across various locations in Osaka Prefecture will showcase the unique charm of each region. From stylish displays in urban commercial facilities to heartwarming lights rooted in local communities, you can enjoy a wide variety of programs.

"Midosuji Illumination," in Osaka was recognized as the street illumination of the the world-largest scale in January 2015. This year, under the design concept of "Grow-Light," the event aims to create light that grows with the city and its people. We offer a variety of projects including light art created through public participation workshops and projection mapping. Enjoy the dazzling light performances along Midosuji Ave.!

A diffractive diffuser is a kind of diffractive optical element (DOE) that exploits the principles of diffraction and refraction. It uses diffraction to manipulate monochromatic light, giving it a specific spatial configuration and intensity profile. Diffractive diffusers are commonly used in commercially available LED illumination systems. Usually, the diffuser material is GaN or fused silica with processed rough surfaces. LED diffusers can be characterized online using scatterometry-based metrology.[3][2]

A flash diffuser (also called a speedlight diffuser, or shoot-through diffuser) spreads the light from the flash of a camera. A diffusion filter of this type may also be used in front of a non-flash studio light to soften the light on the scene being shot; such filters are used in still photography, in film lighting, and in stage lighting. In the film and stage industry, a diffusion filter may also be called diffusion gel, or just diffusion. This is by analogy to a color gel, which is another type of lighting gel. Shōji are diffusing window/doors.

In effect, the light will not come from one concentrated source (like a spotlight), but rather will spread out, bounce from reflective ceilings and walls, thus getting rid of harsh light, and hard shadows. This is particularly useful for portrait photographers, since harsh light and hard shadows are usually not considered flattering in a portrait.

Diffusion filters may be used to diffuse the light falling on the subject, or placed between the camera and the subject for a hazy effect.

"Midousuji Illumination" shines Midosuji Ave., the main street of Osaka. "OSAKA Hikari-Renaissance" illuminates Nakanoshima, the symbol of aqua metropolis Osaka. Besides these two core programs, Area program present fantastic and dazzling nights at many locations in Osaka Prefecture.

Silk sheets can also be used as diffusers, and in fact were until the invention of translucent plastics. "Opal" is a common translucent or opalescent diffusion.

"Diffusion filter" may also refer to a translucent photographic filter used for a special effect. When used in front of the camera lens, a diffusion filter softens subjects and generates a dreamy haze. This effect can also be improvised by smearing petroleum jelly on a UV filter or shooting through a nylon stocking. Diffusion filters may be uniform or may have a clear center area to create a vignette of diffused area around the clear center subject.

In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light. Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.

A perfect (reflecting) diffuser (PRD) is a theoretical perfectly white surface with Lambertian reflectance (its brightness appears the same from any angle of view). It does not absorb light, giving back 100% of the light it receives.[1] Reflective diffusers can be easily characterised by scatterometers.[2]

Recently, photopolymers have been used for making holographic diffusers. Photopolymers offer better performance than other materials and have a large viewing angle. Also, the process of synthesizing photopolymers is much simpler.

At OSAKA Hikari-Renaissance, beautiful light programs are held utilizing the scenery spreading around the waterfront of Nakanoshima, the symbol of aqua metropolis Osaka. We reconsider our roots as a "Water City" and connect the relationship between the waterfront, people, and the city like the "808 Bridges" of the past.
