Digital cameras can exhibit the effect of color shifting due to infrared light in dark colors. In some situations, black material with different dyes are rendered in different color tones due to this infrared contamination. The effect of this color shift can be exascerbated by adding ND filters for acceptable exposure instead of stopping down the lens iris. Schneider Optics has introduced Platinum IR filters to correct for this effect. Platinum filters are available as a straight IR filter or incorporated into ND filters from densities .3 to 1.8 (one to six stops of compensation). These Platinum IR ND filters reduce exposure while also blocking infrared light. Watch my video above to learn more.
