G-Force : Digital Film FX : A single Photoshop-compatible plug-in filter for B&W grain effects.
It produces results similar to using traditional "fast" B&W camera film, allowing more control than the standard "noise" filters included with most image-editors. Give your photos back some of that artistic texture which seems to be sadly missing these days!
Ideal for both landscape scenes or portraits. For best results use with high-resolution images. This is just one of the photography-related filters from the "Fotomatic" series by Cybia, so be sure to check out the others that are available.
