Stylization and Artistic Filters

Increases edge contrast to give an apparent sharpness boost.

• -Amount — strength of sharpening
• -Radius — how wide the sharpening halo is around detected edges
• -Threshold — minimum edge contrast required to trigger sharpening (prevents sharpening noise)

Finds and highlights edges in the image.

• -Sobel — classic edge detection; produces a high-contrast outline of shape boundaries
• -Canny — fine, single-pixel-wide edges; more detailed
• -Laplacian — detects edges in all directions simultaneously; produces a dotted/blob pattern on some images

Produces a raised bas-relief appearance.

• -Direction — the direction of the virtual light source (determines which side of edges is highlighted)
• -Strength — height of the emboss effect
• -Blend Mode — usually set to Overlay or Hard Light to combine with the original image beneath

Reduces the number of tonal levels in the image, creating a flat, graphic, poster-art appearance.

• -Levels — the number of distinct tonal values per channel (2 to 8 range is most dramatic; higher values are subtler)

Divides the image into a grid of large pixel blocks.

• -Block Size — the size of each block in pixels

Converts the image to a simulated halftone dot pattern.

• -Dot Size — radius of each dot
• -Angle — rotation of the dot grid (traditional printing uses approximately 45 degrees to reduce moire)
• -Mode — Round Dots, Lines, Crosses, Diamonds
• -Color Mode — Monochrome or CMYK (separate screens for each channel)

Converts the image to a pencil drawing simulation.

• -Line Density — number of sketch lines
• -Line Weight — thickness of lines
• -Shading — amount of cross-hatching and tonal shading in the result
• -Color Mode — Grayscale Sketch or Colored Sketch

Simulates an oil painting surface.

• -Stylization — the degree of paint stroke abstraction
• -Brush Scale — size of simulated brush strokes
• -Direction — flow direction for brush stroke orientation

Soft, organic watercolor simulation.

• -Flow — wetness of simulated paint; higher values create more blending and blooming
• -Edge Darkening — intensity of edge outlines (common in real watercolor work)
• -Granulation — roughness of paper texture in the simulation

Separates RGB channels and offsets them to simulate lens chromatic aberration or digital glitch artifacts.

• -Offset X / Y — horizontal and vertical separation of channels
• -Intensity — how dramatically each channel is displaced
• -Mode: Chromatic Aberration (smooth lens distortion), RGB Shift (angular separation), Scan Lines (horizontal line displacement artifacts)

Adds random pixel variation to simulate film grain or digital sensor noise.

• -Amount — intensity of the noise
• -Grain Size — size of individual noise particles
• -Color Mode — Monochrome Grain (brightness variation only), Color Grain (independent RGB channel variation)
• -Luminance Weighting — concentration of grain in shadows, midtones, or highlights
