Realgrain Plugin for Mac

From Imagenomic:

If you long for the darkroom age, the soft, warm graininess of the film, or you seek to infuse that fuzzy, retro look or perhaps enhance your digital photos by simulating the greater range and texture of traditional film, then Realgrain is the plugin for you.

Realgrain features versatile methods for simulating the grain patterns, the color and the tonal response of different films and different scan resolutions to convey a truly film-like image effect.

Because Realgrain enables you to automatically adjust the grain size based on the physical image dimensions, it can dynamically render accurate grain patterns for varying image sizes.

Realgrain's controls for grain balance, tonal and color fine-tuning enable you to generate superior output quality and picture vibrancy, and are simple and easy-to-use for a truly intuitive workflow experience.

Plus, Realgrain comes with precision presets for a range of default effect options. You can also capture your own signature workflow through custom presets tailored to your specific requirements and individual photographs.
