Fluorescent Light Filters

Standard cool-white or daylight fluorescent tubes offer a reasonable approximation of photographic daylight except for their excessive green content. Two separate techniques are available to deal with this situation: (1) balance all sources to the fluorescent, or (2) balance the fluorescent to the sources. Rosco Product 3304 is applied to windows or daylight sources and 3306 is applied to 3200 K sources to balance them to the fluorescent lights. Rosco Products 3308, 3313, 3314, 3310, and 3311 are applied to fluorescent lights to convert them to either 3200 K or nominal daylight. A roll of the material is generally a little over 100 sq. ft. (54 in. by 25 ft.), and the products are optically clear.
