Publisher description for Asiva Grain

Asiva Grain program icon

The Asiva Grain plug-in allows you add grain to images, which is useful when working with digital images that have a synthetic or ???Plastic??? feel. This gives texture and feel to an otherwise sterile image. By specifying grain amounts in the color component sliders in Combination with relative levels in the three HSI curves, one can create grain patterns Similar to those found in various film speeds and stocks. The Asiva Grain filter can be applied in three different color spaces: the image color space (RGB or CMYK), HSI (Hue-Saturation-Intensity), or YUV (Luminance-Chrominance). For the color space selected, sliders allow you to select the maximum grain amount for each color component in the selected color space. Note that the three curves in the three Asiva?? Maps then determine the relative grain amount depending upon hue, saturation and intensity curves. Define the source colors you wish to add grain to, using the built in Hue, Saturation and Luminance (HSV) curves or maps. Sampling the colors in the area/s or an image you wish to affect with the built in Color Sampler Tool is a simple way of selecting these values. Adjusting and fine tuning the curves in the maps allows you to include or exclude certain H or S or V (Luminance) values affected. The slope of the curves will define how The Filter is transitioned. A near vertical line on your Map will create sharply defined boundaries between where the filter is applied and is not, and a gently sloped curve on the Map will make the boundaries less defined or 'feathered'. Since there are three maps (Hue, Saturation and Luminance) to work with, you will be able to 'feather' those boundaries based on their Hue, Saturation or Luminance value differences. Asiva's curves are so PRECISE, that tedious masking prior to application of the filters are often not necessary. The Grain filter may also be applied to your Photoshop selections.
