This color shift is directly affected by the infrared spectrum. Specifically, in high definition photography, the sensitivity of imaging sensors to IR has become a challenge. This is particularly evident when using standard neutral density filters that absorb visible light but pass infrared. \u003c\/p\u003e \u003cp\u003eUnlike many photographic films, the CCD or CMOS of a digital camera is inherently susceptible to infrared contamination, even when the manufacturer attempts to reduce this problem by adding an infrared absorbing filter on top of the image sensor. Because these filters do not have a sharp cutoff at the infrared wavelengths there has to be a compromise in order not to exclude visible red wavelengths. This results in some infrared wavelengths being allowed to pass.\u003c\/p\u003e \u003cp\u003eWhile minor infrared contamination does not normally cause much of a problem for visible images, when using conventional neutral density filters especially denser grades, this issue is multiplied by the filter factor. Tiffen has now addressed this problem with the introduction of its exclusive line of their Infrared Hot Mirror filters. Hot Mirror filters completely block infrared throughout the entire spectrum.\u003c\/p\u003e \u003cp\u003eA 0.6 (2 stop) Neutral Density filter is often considered an average ND filter to use that normally compensates for preventing a bright, washed out image when shooting with a high ISO in bright light. However, it is purely situational as to which degree of ND you should use in any given venue. By slowing down your shutter speed even more, you will begin to see more movement in the image such as the blurring of water. The difference between fore\/background becomes more noticeable.\u003c\/p\u003e \u003cp\u003eTiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ch3\u003eNeutral Density Filters Have Four Main Uses\u003c\/h3\u003e \u003cdl\u003e \u003cdd\u003eTo enable slow shutter speeds to be used, especially with high speed ISOs, to record movement in subjects such as waterfalls, clouds, or cars\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eTo decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eTo decrease the effective ISO of high speed film (above ISO 400) and allow it to be used outdoors in bright situation\u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdd\u003eTo allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which could cause overexposure\u003c\/dd\u003e \u003c\/dl\u003e \u003c\/div\u003e \u003cdiv\u003e \u003ch3\u003eColorCore Technology\u003c\/h3\u003e \u003cdl\u003e \u003cdd\u003eAs with all Tiffen filters, IR ND filters are ground and polished to provide the greatest level of flatness and parallelism.
