Sketch filters use many active colors, background and foreground ones, in order to change an average colored image into a dichromatic one, stylizing the image according to one or another drawing technique.
Move to menu Filters>Sketch to you find the following sketch thumbnails:
1. Bas Relief
This filter uses active colors to create an effect of an illuminated relief background. Dark areas of the image are painted with the foreground color, light areas - with the background one.
Let's get started by opening the image and choosing Filter>Sketch>Bas Relief. You will see the following settings:
Detail - controls the degree of detail in an image (I chose 14).
Smoothness - controls the degree of smoothness of an image (I chose 3).
Light - determines the direction of illumination. You can choose up to eight basic directions (I chose Right).
Here's what I came up with:
2. Chalk&Charcoal
This filter draws the image with diagonal lines: chalk ones and coal ones, both done in a foreground color.
Now open the image and select Filter>Sketch>Chalk&Charcoal. You will see the following settings:
Charcoal Area - determines the portion of the image that is done in Charcoal (I chose 6).
Chalk Area - determines the portion of the image that is done in Chalk (I chose 5).
Stroke Pressure - controls the image contrast (I chose 1).
Here's what I came up with:
3. Charcoal
This filter simulates drawing with charcoal in a foreground color on paper of a background color. Middle tones of the image are streaked with charcoal along diagonal line, main contours are crisply outlined with thick lines in a foreground color, light areas get one homogeneous fill color.
And so we begin. Open the image and select Filter>Sketch>Charcoal. You will see the following settings:
Charcoal Thickness - controls the thickness of the hatching (I chose 2).
Detail - controls saving the details of the image (I chose 5).
Light/Dark Balance - determines the portion of the image to be done in charcoal (I chose 44).
Here is my result:
4. Chrome
This filter simulates chrome plating. Light areas give the impression of convex areas, dark ones - of concave areas.
Begin by opening the image and selecting Filter>Sketch>Chrome. You will see the following settings:
Detail - controls the degree of detail in your image (I chose 7).
Smoothness - controls the degree of smoothness of your image (I chose 8).
Here's what I got as a result:
5. Conte Crayon
This filter simulates drawing with an Italian pencil or conte crayon on material of a varied texture.
Let's begin. Open your image and select Filter>Sketch>Conte Crayon. You will find the following settings:
Stroke Length - adjusts the depth of the foreground color (I chose 8).
Stroke Detail - determines the depth of the background color (I chose 6).
Texture - in the drop down list that appears here, you have a choice of texture, that is to say, the material, on which the image is imprinted. You'll find textures like these: Brick, Burlap, Canvas, Sandstone. You can also download your own texture (I chose Canvas).
Scaling - changes the scale of the texture in relation to the image (I chose 67%).
Relief - increases the contrast of the texture, and is used for getting more relief in textures (I chose 4).
Light - regulates illumination: is used to change Light Direction (I chose Top).
Invert - inverts the texture, and during the inversion process all convex areas become concave and vice versa (I chose to leave the box unchecked).
Here's what I came up with:
6. Graphic Pen
This filter simulates drawing with feather and ink. A painting is done in stokes with various directions.
And so we begin here by opening the image and selecting Filter>Sketch>Graphic Pen. You'll find the following settings:
Stroke Length - determines the length of the hatch marks (I chose 15).
Light/Dark Balance - controls the illumination of the picture by increasing the share of the hatched surface (I chose 15).
Stroke Direction - is the direction of the strokes, with up to 8 possible directions (I chose Right Diagonal).
Here's my result:
7. Halftone Pattern
This filter repaints the image in two colors, adding a rasterized pattern to the image.
Let's open the image and select Filter>Sketch>Halftone Pattern. You'll see the following settings:
Size - adjusts the size of the pattern that colors an image (I chose 1).
Contrast - controls the contrast of the image (I chose 2).
Pattern Type - allows users to choose the type of pattern used. The following types are available: Circle, Dot, Line (I chose Dot).
Here's what I got:
8. Note Paper
This filter gives the effect of notebook paper of a background color glued to paper of a foreground color.
We begin by opening our image and selecting Filter>Sketch>Note Paper. You'll find these settings:
Image Balance - controls the relationship between the areas of foreground and background colors (I chose 33).
Graininess - gives the paper a grainy effect (I chose 12).
Relief - adds a relief look (I chose 9).
Here is my result:
9. Photocopy
This filter creates the photocopy effect. Dark areas are preserved only along the basic contours of the image. Middle tones become either dark or light shades, depending on their clarity.
To begin, we open an image and select Filter>Sketch>Photocopy. Here you'll find the following settings:
Detail - controls the image details (I chose 16).
Darkness - determines the intensity of the colors (I chose 3).
Here's what I came up with:
10. Plaster
This filter imbues an image with relief qualities: dark areas are raised and light areas are lowered.
To begin, we open our image and select Filter>Sketch>Plaster. You'll find the following settings:
Image Balance - determines the level of brightness, that separates foreground and background colors. (I chose 36).
Smoothness - adjusts the degree of smoothness in an image (I chose 1).
Light - determines the source of illumination, can be set in one of 8 directions (I chose Left).
My result:
11. Reticulation
This filter imitates the effect of reticulation - photo emulsion decompositions on film. Grain is more noticeable in light places.
To begin, we will open an image and select Filter>Sketch>Reticulation. You'll find the following settings:
Density - controls the density of dots (I chose 4).
Foreground Level - adjusts the intensity of the foundation color in the image (I chose 10).
Background Level - adjusts the density of the background color in the image (I chose 20).
Here's my result:
12. Stamp
This filter creates the rubber or wooden stamp effect. The image is significantly simplified and filled with two colors only.
Let's open the image and select Filter>Sketch>Stamp. You'll find these settings
Light/Dark Balance - controls the border between foreground and background colors (I chose 11).
Smoothness - adjusts the smoothness of sharp edges and borders (I chose 4).
Here's my result:
13. Torn Edges
This filter imitates paper with torn edges and fills the image with background and foreground colors.
Now, open your image and select Filter>Sketch>Torn Edges. You'll find the following settings:
Image Balance - determines the ratio of foreground and background colored areas (I chose 34).
Smoothness - adjusts the smoothness of sharp borders (I chose 11).
Contrast - adjusts the contrast in blending between colors (I chose 6).
Here's what I came up with:
14. Water Paper
This filter imitates a drawing on wet paper. The image retains the initial colors.
Let's start. Open your image and select Filter>Sketch>Water Paper. You'll find the following settings:
Fiber Length - adjusts the length of fiber paper (I chose 8).
Brightness - controls the brightness of the image (I chose 64).
Contrast - controls the contrast of the image (I chose 54).
Here's what I got as a result:
