BestDealUSA 67mm Soft Focus Effect Diffuser Lens Filter For Sony Canon Nikon 67mm Lens
Description:Soft focus effects are common in fashion and advertising images. In certain circumstances, a soft focus  treatment of a landscape can enhance the mood of an image by creating a  soft glowing atmosphere, and can be particularly effective for backlit  subjects. Soft focus is not the same as out of focus, and is not about  degrading the image, but rather about subtly changing the image to  convey a desired interpretation to the viewer.The key to a  successful soft focus image is to maintain a sharp rendition of the  subject while adding a supplementary softer image. Traditionally with  film this is achieved by use of patterned glass or plastic filters, by  stretching a fine mesh over the lens, or less controllably, by breathing  on the lens. These methods all work by allowing most of the light  entering the lens to pass straight to the film while diffracting a small  amount of light to give the desired effect. Of course this means that  the decision to use a soft focus effect must be taken at the time the  photograph is taken; with digital manipulation we have the luxury to  apply a soft focus interpretation at any time, and to have much greater control than is possible using filtration with film.This Optical Diffuser provides a minimum of diffusion and is most commonly used in portraiture; however, it can also be used in landscape photography. The diffuser has very  little effect on the sharpness of the image. It merely diffuses  highlights, reducing contrast and can creates a soft halo around the  highlights. It is also ideal for creating a hint of softness or blurred  contours. As such, diffusers can be used to soften a landscape, or  soften skin texture in a portrait to hide minor flaws, giving a gentle,  flattering effect.Package Contents:1 x 67mm Soft Filter
