The Hitech 67mm Warm2Cool Filter is a variable color enhancement filter providing a diversity of color possibilities from cooling blues to warming yellows. You can easily manipulate the effect of the filter by rotating the front filter ring in order to browse through the fluent range of tones. This eliminates the necessity to carry multiple color correction filters or to be dependent on one type of colored filter.
