Photographers understand that when practicing their craft a filter is a thin piece of glass that is placed over the camera lens that allows for various image effects to be transferred to the photograph. Filters can also balance out glare or provide enhancements such as adding light in a darkened space. There are filters on the market that “polarize” which means they are able to balance wide landscape photos and can also provide “warm” or “cool” effects to an image. Another filter that photographers rely on is a ultraviolet (UV) filter.
What does a UV filter do?
Ultraviolet light is light that is in the non-visible spectrum. Even though this light is not visible to the human eye, it can wreak havoc with photographs if not properly addressed. Much as the way UV light can harm your skin, it can also limit your camera’s ability to capture contrast in a photograph. A UV filter filters out the UV rays and eliminate the potential for “purple hazing” around the photo edges. UV lenses are clear, thin and pop onto the front of your camera lens.
Photographers continue to debate whether UV filters are needed if you’re shooting with digital cameras rather than with film. Digital photographers feel that the sensors built into digital cameras make the device less sensitive to UV light than does cameras that use film. In fact, some photographers that use digital technologies feel that a UV filter can cause their images to be less sharply focused.
UV filters provide an additional layer of protection to your camera lens in addition to blocking UV rays and potentially enhancing the images you capture.
Universe Kogaku America adds to its existing line of Quartz lenses, a new 12mm lens for imaging applications in the non-visible light spectrum. This lens is a reasonably priced solution to the growing need for imaging in the other than visible spectrum.
