Filter Description:
The Warm2Cool is a first of its kind filter that allows the user to warm up or cool down an image by simply rotating a filter. The unique design of the filter eliminates vignetting on wide angle lenses, as the front rotating element is larger than the screw on element. Markings on the ring also provide the photographer with a guide to the colour they can achieve (photographers should always test the filter first to ensure the correct colour is achieved before committing to a final shot).
