Zenoté Grain

Zenoté Grain will add various levels of noise to your image. This can be used to add an edginess to your look or sotften the edges of video footage. Skillful use of this tool can also simulate various film stocks.

The amount parameter determines how much grain to add to the image. Larger numbers will be more visible. The grain is added based on the content of the image so most grain is visible in the middle ranges and becomes nearly invisible in the darkest and brightest sections of the image. Be careful not to add too much unless your intention is to make the grain obvious. Even a very low number goes a long way toward fooling the eye.

Size determines the size of the grain and the general "clumpiness" of the grain added. Using several different sizes of grain chained together can create some amazing effects.

The channel setting determines where the grain is applied. You can add grain to all channels equally resulting in monochromatic grain. You may also apply grain to each channel separately or to all 3 channels with different values to create RGB grain.

The transfer mode allows you to set how you want the original image mixed with the grain. The possible choices for transfer mode are Normal, Darken, Lighten, Screen, Multiply, Difference, Additive, Dodge and Burn.

• Normal mode will simply blend evenly between the grain and the image based on the amount setting.
• Darken mode will compare the image and the grain and take the darker pixel at each location in the image.
  Lighten is similar to darken mode except that the lightest pixel is selected.
• Screen blending mode will brighten the pixel based on how bright its original value is. A black pixel will not be lightened at all while a lighter pixel will have its value updated.
• Multiply will mutiply the values of each image from the center value. This has the effect of making the darker pixels darker and the brighter pixels brighter.
• Difference will compare the 2 images and will set the pixel vaule based on the difference between the 2. Where there is no change you will see the original image. Where there is a difference, the color will be brighter. This creates an interesting effect but does not result in realistic or natural world colors.
• Additive will add the 2 images together. This creates a general lightening of the image.
• Dodge will adjust the areas to grain based on the darker value of luminance between the grain and the image.
• Burn is a mode similar to dodge but will bias the brighter values.
  

The Render Settings check box will allow you to render the current settings being used to your video for test and comparison purposes.
