Using the Oil Brush tool
You can use the Oil Brush tool to simulate a dense medium that blends color by mixing with a thick medium, rather than through an overlay function. You can load the Oil Brush tool with multiple colors. You can smear and blend colors by mixing them with oil that is already on the canvas.
There are a number of options for managing the reloading of the Oil Brush tool head between strokes. You can
• |
reload the brush with a solid color
|
• |
reload the brush by sampling from the Mixer page
|
• |
reload the brush with its current contents and optional amounts
of color from the Mixer page
|
• |
leave the brush unloaded, and dip into the palettes or canvas after
each stroke
|
Paint strokes applied by the Oil Brush tool are wet in terms of how strokes interact with other strokes by smearing or mixing together. For more information see To dry or wet an Art Media layer.
Oil Brush tool options |
Edit workspace
Oil Brush tool options include
• |
Shape — defines the shape of the brush tip
|
• |
Size — defines the size of the tool head in pixels
|
• |
Thickness — defines the aspect ratio of the tool head. This setting
is active only when the Fixed angle Head Tracking option is
chosen.
|
• |
Rotation — defines the angle of head rotation in degrees
|
• |
Head Tracking — determines whether the tool head bends around
the path of the user’s stroke, or remains at a fixed angle
|
• |
Head Loading — defines the percentage of material on the brush
at the start of the stroke
|
• |
Viscosity — defines the rate at which the material on the brush is
applied, and thus the length of the stroke before your paint runs
out
|
• |
Firmness — defines the amount of splay in the brush, how the
rendered line gets wider with more pressure, and how well it
penetrates the surface on to which it is painting
|
• |
Bristle size — affects the underlying noise function for texture and
application of paint
|
• |
Auto Clean check box — cleans the brush and reloads it with fresh
paint at the start of a new stroke
|
When unmarked, the brush head is not cleaned at the start of the stroke. Instead, the dirty head has a small amount of the current color added to whatever dirty head state exists from the previous stroke. |
• |
Clean button — cleans the head and start the next stroke with
fresh paint or pigment
|
The Auto Clean check box and the Clean button are only available with the Oil Brush and Palette Knife tools. |
• |
Trace check box — allows the current Art Media tool to select the
pigment or paint color by sampling the data below the center of
the brush regardless of the layer type.
|
Important! When you hold down the mouse button to begin the
stroke, note that a single sample is performed and the resulting
color is used for the duration of the stroke.
