This tab is used to control the infrared (IR) cleaning, restore colors, grain reduction and sharpening options.
Filter options affect the output of cropped TIFF or JPEG files and the images in an index. They do not affect the data of a raw scan file.
The one exception to this is if "Output|Raw output with" is set to "Save" - in this case, the infrared cleaning and grain reduction is also done before saving the raw scan files.
See the Processing section of the topic "How VueScan Works" to understand the details of how these filters are applied.
