Normally we strive to produce the sharpest images possible. However, one common exception occurs when printing portraits. Most subjects don't appreciate having lines, wrinkles, and skin blemishes revealed in sharp detail. Portrait Diffusion Grids have been used for decades to soften and minimize the appearance of those unwanted facial details. Unlike diffusion filters which simply blur the image, projecting the image through the steel mesh grid uses diffraction to reduce resolution. The effect can be controlled by changing the lens aperture, adjusting the distance between lens and grid, or making only part of the exposure through the grid.
The #429-013 Portrait Diffusion Grid is designed be installed on Omega D-2, D-3, D-4 4x5 enlargers, as well as B-series 6x9, E-series 5x7 and F-series 8x10 enlargers using the accessory attachment bracket on the lens mounts.
