1 — According to the previous studies, it is found that the Bi2S3 is a good cocatalyst, which has a high photoelectron conversion efficiency.

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]

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.

Produced by Glide, the creator of the popular video messaging app of the same name, the CMRA will come in white, blue, gray and black and will sell for $149 to earlier buyers and $249 when becomes available via normal retail. Early buyers are expected to receive the device in spring of 2017.

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.

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.

Of all the Apple rumors we've heard in recent months, a dual HD camera on the Apple Watch wasn't among them, so this product, which is touched by someone with a genuine Apple background, will likely be a welcome surprise.

Developed by former Apple Watch engineer Shawn Grening, the band features two cameras, a front-facing 8-megapixel camera and a self-facing 2-megapixel camera. Both cameras capture HD photos and video, which can be saved to the band's 8GB of embedded storage.

What is diffused light for plants

"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.

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]

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.

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.

So is this the accessory that will turn the Apple Watch from a relatively niche device (Apple still won't release unit sales numbers on the device) into a mainstream hit? Possibly. The selfie camera alone could be enough to boost Apple Watch sales.

Along with band, the company has also created a unique charging dock that can charge the CMRA band and the Apple Watch simultaneously. That rechargeable charging dock has the ability to recharge both the Apple Watch and the CMRA band two times each.

Perhaps the most amazing thing about the well-designed device is the fact that Apple didn't think of it first. When the Apple Watch first launched, the first thing many analysts compared it to was the fictional smartwatch worn by Dick Tracy, a device that had its own embedded camera.

Fans of the Apple Watch have mostly expressed satisfaction with the device's existing functions, with most of the conversation revolving around longer battery life and a thinner form factor in future models. But the arrival of a dual-camera addition was probably more than any Apple Watch lover hoped for.

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.

Despite its many functions, one of the biggest questions about the Apple Watch from its critics — namely, what is it for? — may have finally been answered. Now it's a selfie camera viewer and video recorder on your wrist, when combined with the new CMRA camera band for Apple Watch.
