Description
- Hoya 55mm DUTO Filter
HOYA 55MM DUTO/DIFFUSER FILTER Both are diffusion type filters but DIFFUSER gives a soft-focus effect due to its irregularly uneven surface while DUTO has fine concentric lines etched on its surface. The center of the picture is usually sharp with DUTO but DIFFUSER gives an overall soft-focus effect. Both are particularly effective in portraiture and commercial photography
