# Introduction

The digiKam image plugin Filmgrain is an easy tool to produce film grain on your images as known from classical high speed film material as, for example, the famous B/W KodaK Tri-X. In order to increase film sensitivity, manufacturers employed larger silver grains in the photo emulsion.

The film grain effect gives your shot a particular mood or seems to transport it in time. The treated image acquires a timeless atmosphere, detached from every day life. If you want that gritty, art-house, street-photography grainy film look, especially in monochromatic photos, use this plugin.

## Using the plugin

There is a slider calibrated in ISO-sensitivity to control the grain intensity and granularity. The default is set to ISO-2400, although higher values are often required. If you still want more grain, apply the filter several times.

## The plugin in action

This is an example of the film grain effect applied on a black and white image. The original image is (1) and the corrected image is (2). The film sensitivity used for simulate the film graininess is ISO-1600.
