Classic style lets you create color and B&W drawings with well-defined contour lines.
A characteristic feature of this style is its accuracy: the
image looks as if it was primarily created by contour lines with the
addition of hatching. Though this mode is versatile and good for many
purposes, it is the most suitable for technical illustration, architectural
images, and other pictures where you would like to attain good detail.
Pencil Sketch from Photograph: Classic Style in AKVIS Sketch
(Move your mouse over the image to see the original version)
In the Sketch tab you can adjust the parameters for the photo-to-sketch conversion.
Note: You can see the conversion result immediately, as you move the slider, only in the Preview Window. To convert the whole image, press the button
or click on the After tab.
Effects tab:
Watercolor. The Watercolor parameter lets you create watercolor drawings. This parameter accepts values between 0 and 50. By default it is set to 0 which corresponds to a pencil drawing. As you move the slider to the right (that is, increase the value of the parameter) the strokes get blurred, contrast and detail get weaker, as if the strokes were drawn on wet paper. The higher the value of the parameter, the stronger the effect.
Watercolor = 10
Charcoal. The parameter changes the drawing technique from a fine pencil drawing to charcoal. The higher the value of the parameter, the more it looks like the charcoal technique.
Charcoal = 7
Coloration. The effect adds color to a drawing provided by the color information from the original image (if the image is not grayscale). The parameter accepts values between 0 and 100.
By default the value is set to 0, which corresponds to a graphite pencil sketch, in this case the pencil sketch is not mixed with the original image.
As you move the slider to the right, the drawing gets colors from the original image. If at the same time the parameter Watercolor has a value higher than 0, the sketch looks very similar to a watercolor drawing.
Coloration = 40
Smudging. The parameter creates the effect of smearing hatching in midtone areas without affecting the contour lines of the drawing. This technique looks like a result of rubbing across a drawing with a stump tool, smooth paper, or a finger. The parameter accepts values between 0 and 30. By default it is set to 0 at which there is no smudging effect. At higher values the appearance of shaded areas changes. Shading becomes similar to soft graphite. It is a fast and simple way to add a soft and blurred texture to a sketch.
Smudging = 0
Smudging = 30
Strokes tab (hatching parameters):
Color Pencil. When the check-box is enabled, the program imitates a color pencil drawing. When the check-box is disabled, the strokes are black.
The check-box "Color Pencil" is enabled
The check-box "Color Pencil" is disabled
When the check-box Color Pencil is enabled, you can change the Saturation of the image by moving the slider to the right of the check-box. As the value of this parameter is increased, the intensity of colors in the image become more intense, and colors of the strokes become more "bright".
Saturation = 0
Saturation = 100
Angle. This parameter Angle sets the pitch angle of the strokes when hatching a uniform area (an area that does not contain edges and intensity swings). By default the strokes in such areas are drawn at a 45 degree angle. The parameter has values between 0 and 180 degrees; the step is 5 degrees.
Angle = 45
Angle = 135
Angle = 90
Stroke Thickness. This parameter sets the stroke size. If you reduce the value of the parameter the strokes on the picture get thinner and harder, if you increase the value the strokes get wider and blurred on their edges.
Stroke Thickness = 5
Stroke Thickness = 9
Min Length/Max Length. This parameter sets a range within which the stroke length can vary. There are two sliders to define the range borders: the left slider sets the minimum length, the right slider sets the maximum length. The resulting sketch will be made up of strokes that fall within this range.
If you reduce the minimum length, the number of strokes and the detail of the image increase. Visually the drawing becomes darker. If you increase the value of the minimum length, the number of strokes is reduced (strokes shorter than the set minimum do not get drawn). Visually the image becomes lighter and neater.
If you increase the maximum length, the hatching becomes less uniform. The higher the value of this parameter, the longer strokes can be drawn on the picture. However, if the value is too high it may worsen the precision of the hatching.
Min Length/Max Length=1/4
Min Length/Max Length=8/16
Midtones Intensity. This parameter defines the intensity of the midtone strokes, as if drawn with different pressure. As you move the slider to the left, the midtone strokes fade - becoming dim and blurred. As you move the slider to the right the midtone strokes become thicker and more intensive.
Midtones Intensity = 1
Midtones Intensity = 10
Midtones Hatching. This parameter defines the level of hatching in the midtone areas. If you want to reduce hatching move the slider to the left.
Midtones Hatching = 1
Midtones Hatching = 100
Edges tab (parameters that affect how edges are drawn):
Edge Strength. This is the main parameter used to control edges, by adjusting the intensity of lines and details. At lower levels there are fewer edges and the level of detail decreases, while at higher values more edges are drawn and more detail is present.
Edge Strength = 0
Edge Strength = 50
Edge Strength = 100
The Edge Tracing check-box is used to detect the additional edges between areas that don't have well-defined transitions in brightness. Its affect can be adjusted further by these two parameters:
Sensitivity. The higher the value of this parameter the more transitions between colors will be retrieved and the more edges will be defined by lines instead of hatching. If you want to emphasize the edges, increase the value of this parameter.
Sensitivity = 10 (Edge Width = 15)
Sensitivity = 80 (Edge Width = 15)
Edge Width. This parameter defines the thickness of the outliness. At higher values of this parameter the edges will be drawn by thicker lines.
Edge Width = 10 (Sensitivity = 70)
Edge Width = 60 (Sensitivity = 70)
Direction tab (parameters to control hatching direction):
The parameters under this tab affect hatching when the Stroke Direction tool is used .
The Stroke Direction tool gives you full control over how hatching is drawn on an image. Use this special tool to define the guiding lines, and the program will convert the image into a sketch, directing the hatching to follow them. With this technique you can achieve a truly realistic drawing with patterns and textures going in the right direction.
The tool is not available for the basic Home license; it is active only for advanced licenses like Home Deluxe, Business.
You can use it more effectively by adjusting these parameters:
Zone of Influence - the width of the area affected by stroke guide lines. The higher the value, the more hatching will follow the direction of stroke guide lines.
Zone of Influence = 0
Zone of Influence = 35
Preserve Edges check-box. When this check-box is deselected, hatching will be drawn past edges.
