White Halation Diffusion

Halation diffusion, as discussed last week, causes an effect whereby a source of light acquires a halo in the shot. White halation filters typically do this by producing a clean and sometimes shimmering halo effect but without losing the sharpness of the shot.

Tiffen Glimmerglass for instance creates a subtle effect which subdues colours and contrast but does not destroy sharpness, even at heavy densities.

Glimmerglass takes its name from the shining silver particles within its glass which glisten when you view them. Those particles act to disperse some quantity of the light that passes through them to achieve their effect. Their halation effect is quite soft and clean but is visible on primary sources of light and on specular (reflected) light sources.

Pearlescent filters are similar but add a luscious sheen that disguises the fine details of complexions – this can give your images a stunning, rich glamour which very effectively counteracts the uncharitable level of detail that some modern, digital cameras provide. The halation effect, as with Glimmerglass is subtle and there is no sense of loss of sharpness, instead there is simply a subtle easing of the imperfections of the complexion while eyes remain sharply defined.

For a much more vintage diffusion effect that provides pronounced halations, you want Pro-Mists. Pro-Mists provide timeless glamour, washing out colours and causing faces and light sources to really glow, with a beautiful, old fashioned luminescence.

Finally in the white halation range, we have Satin filters. Satin filters produce a soft and subtle halation effect that softens the light sources and complexions but does not look as if it has been diffused and filtered – providing a very natural, albeit softened look. The harshness of a modern camera’s resolution is broken up without breaking up the image.
