Neutral density filters are light filters that decrease the intensity of light without altering the relative spectral distribution of the energy. They are used to filter the entire visible spectrum ...

Neutral density filters are critical for landscape and portrait photographers. Unsurprisingly, considering their necessity for these types of images, there are a massive number of neutral density ...

Tunable filters are optical filters that are suitable for applications requiring wavelength tuning. Two of their main specifications are the optical density (OD) and the out-of-band rejection. The ...

Without having other variable ND filters for comparison, we can’t make definitive comments on whether the Syrp filter is superior. But we can say that it provides a compact and versatile addition to a ...

Neutral density filters, also known as ND filters or grey filters, are optical filters that reduce light transmission evenly across a portion of the spectrum. They achieve this reduction without ...

The neutral density filter is indispensable for landscape photographers. SOPHISTICATED SLR CAMERAS with their array of lenses can do many things, but there are still situations where a photo can only ...

Variable neutral density filters are very useful for photographers that like manual control in bright light. Instead of paying hundreds of dollars for one, though, you can make your own from just a ...

New Hoya Variable Density filter in sizes from 52 mm to 82 mm. Each filter uses two polarising layers to control the amount of light that passes through the filter and into the camera lens. They can ...
