The Tiffen Filter Wheel 3 Glimmerglass 1/4 filter is a unique way to give your portrait subject a sharp, fresh and flattering appearance. This creative diffusion filter provides you with a graduated way of choosing the degree of filtration that will complement your subject. Whilst Glimmerglass softens fine details such as blemishes, it also adds a soft and flattering glow to the shot that brings an enhanced sense of glamour. The lighter grades of the filter are subtle whilst higher grades will show noticeably more diffusion. The filter also reduces contrast, which will soften the harshness of the shot and present your subject in a more flattering light. The main characteristic of Glimmerglass is that it produces a silvery sparkle on the front face of the filter that gives more confidence to your subject. This sparkle adds a psychological element to the shot that makes your subject more receptive and confident that the session is going well. In this sense, Glimmerglass is as effective to look at as it is to see through. The Glimmerglass 1/4 filter adds more diffusion whilst increasing the glow around your highlights. Contrast continues to be reduced. Tiffen's ColorCore glass is produced by a process that involves permanently laminating the filter material between two pieces of optical glass polished flat to tolerances of one ten-thousandth of an inch, then mounted in precision aluminium rings. Glimmerglass is the first series of filters to offer a "psychological advantage" Glimmerglass softens fine details in a unique way, whilst adding a slight glow to highlights; as contrast is reduced, the appearance is that of enhanced beauty Effective and functional - The glass itself has a distinct silvery sparkle, which has proven doubly useful because when production begins and people see the filter sparkling on the front of the lens, they become more confident that the filter is working for them and they can give a better performance - Tiffen's ColorCore glass is sealed between two sheets of optical glass. In this way, Tiffen can better control the different densities of their filters and thus create more precise degrees of filtration. This process allows for greater colour accuracy compared to glass that is simply tinted and becomes subject to variations during the tinting process Specifications
