If the source image sample color is darker than 50% gray, the background is darkened, similar to multiplying. If the source image sample color is equal to 50% gray, the source image is not changed. Image samples that are equal to pure black or pure white result in pure black or white. The overall effect is similar to what you would achieve by shining a harsh spotlight on the source image.
Hatched Screen Hatched Screen

Height Field From Mask Height Field From Mask
Produces a continuous three-dimensional, loft-shaped height field from a grayscale mask. The white values of the mask define those pixels that are inside the height field while the black values define those pixels that are outside. The field varies smoothly and continuously inside the mask, reaching the value 0 at the edge of the mask. You can use this filter with the Shaded Material filter to produce extremely realistic shaded objects.

Multiply Blend Mode Multiply Blend Mode
Multiplies the source image samples with the background image samples. This results in colors that are at least as dark as either of the two contributing sample colors.
Noise Reduction Noise Reduction
Reduces noise using a threshold value to define what is considered noise. Small changes in luminance below that value are considered noise and get a noise reduction treatment, which is a local blur. Changes above the threshold value are considered edges, so they are sharpened.
Op Tile Op Tile
Segments an image, applying any specified scaling and rotation, and then assembles the image again to give an op art appearance.
Overlay Blend Mode Overlay Blend Mode
Either multiplies or screens the source image samples with the background image samples, depending on the background color. The result is to overlay the existing image samples while preserving the highlights and shadows of the background. The background color mixes with the source image to reflect the lightness or darkness of the background.

Ripple Ripple
Transitions from one image to another by creating a circular wave that expands from the center point, revealing the new image in the wake of the wave.
Saturation Blend Mode Saturation Blend Mode
Uses the luminance and hue values of the background with the saturation of the source image. Areas of the background that have no saturation (that is, pure gray areas) do not produce a change.
Screen Blend Mode Screen Blend Mode
Multiplies the inverse of the source image samples with the inverse of the background image samples. This results in colors that are at least as light as either of the two contributing sample colors.
Sepia Tone Sepia Tone
Maps the colors of an image to various shades of brown.
Shaded Material Shaded Material
Produces a shaded image from a height field. The height field is defined to have greater heights with lighter shades, and lesser heights (lower areas) with darker shades. You can combine this filter with the Height Field From Mask filter to produce quick shadings of masks, such as text.
Sharpen Luminance Sharpen Luminance
Increases image detail by sharpening. It operates on the luminance of the image; the chrominance of the pixels remains unaffected.

Sixfold Rotated Tile Sixfold Rotated Tile
Produces a tiled image from a source image by rotating the source at increments of 60 degrees.
Soft Light Blend Mode Soft Light Blend Mode
Either darkens or lightens colors, depending on the source image sample color. If the source image sample color is lighter than 50% gray, the background is lightened, similar to dodging. If the source image sample color is darker than 50% gray, the background is darkened, similar to burning. If the source image sample color is equal to 50% gray, the background is not changed. Image samples that are equal to pure black or pure white produce darker or lighter areas, but do not result in pure black or white. The overall effect is similar to what you would achieve by shining a diffuse spotlight on the source image.
