When using an oil brush to paint landscapes, the following techniques can be followed to enhance the visual effect and artistic expressiveness of the work:
First, choose the right oil painting brush
Brush type:
Flat-head brush: Suitable for large-scale color application and drawing straight lines, such as the sky, water surface, etc.
Round-head brush: Suitable for depicting details and smooth contours, such as trees, rocks, etc.
Fan-shaped brush: Suitable for creating special texture effects, such as grass, leaves, etc.
Outlining pen: It is used to draw contour lines, making the picture clearer and more accurate.
Bristle material:
Pig bristle brush: It has moderate hardness and good elasticity, making it suitable for thick application and creating texture effects.
Nylon brush: It has high hardness, is wear-resistant and durable, and is suitable for quick application and detailed outlining.
Wool brush: Soft and fine, it is suitable for depicting gentle color transitions and detailed depictions.
Second, preparations before drawing
Canvas processing:
Make sure the canvas is clean, flat, free of dust and oil stains.
Apply a layer of primer as needed to enhance the adhesion of the pigment.
Color matching:
Observe the color changes of natural scenery and choose appropriate pigments for matching.
Pay attention to the use of warm and cool tones to create the atmosphere and emotion of the picture.
Third, drawing techniques
Large-scale color application
Use a large flat-tipped brush to dip the paint and start applying the color from the background of the picture.
Pay attention to the consistency of the pigment. If it is too thin, the color will be uneven; if it is too thick, it will be difficult to apply evenly.
During the coloring process, the direction and force of the brushstrokes can be adjusted in a timely manner to create different texture effects.
Detail description:
Use a small round-tipped brush or a outlining pen to dip in the paint and start depicting details such as trees and rocks in the foreground.
Pay attention to the lightness, heaviness, speed and quickness of the brushstrokes to express the texture and form of the object.
The techniques of “points, lines and surfaces” can be employed to make the picture more vivid and three-dimensional.
Light and shadow processing
Observe the changes of natural light to determine the direction and intensity of the light source.
By using the technique of light and shade contrast, the three-dimensional effect and spatial sense of the object are expressed.
Some cool-toned pigments can be appropriately added in the dark areas to make the picture more stable and profound.
Color transition
Between adjacent colors, wet painting or gradient effects can be used for transition.
When the paint is still wet, gently sweep the adjacent color areas with a clean brush to allow the colors to blend naturally.
A smooth transition of colors can also be achieved by adjusting the concentration of the pigment and the direction of the brushstrokes.
Texture effect:
Use brushes or tools of different materials, such as scrapers and sponges, to create rich texture effects.
You can use a scraper to scrape out the texture when the paint is still wet, or gently pat the picture with a sponge to add layers and interest to the picture.
Fourth, precautions during the drawing process
Pigment drying property:
The drying speed of oil paints is relatively slow. One needs to be patient and wait for each layer of paint to dry before proceeding with the next layer of painting.
When the paint is still wet, avoid excessive rubbing or touching the picture to prevent damaging its effect.
Picture composition:
Before drawing, carefully observe the composition characteristics of the natural scenery to determine the primary and secondary relationship and visual center of the picture.
Pay attention to the balance and stability of the picture, and avoid being overly crowded or spacious.
Color application:
One should be good at using the contrast and harmonious relationship of colors to make the picture more harmonious and unified.
Some complementary colors or adjacent colors can be appropriately used for matching to enhance the color effect of the picture.
Fifth, post-treatment and maintenance
Picture retouching
After completing the drawing, carefully check the picture to see if there are any omissions or areas that need adjustment.
If necessary, a fine brush can be used for trimming and improvement.
Protective coating
To make oil paintings more durable, a protective coating can be applied to the surface, such as varnish or varnish, etc.
This can not only protect the picture from being eroded by dust and stains, but also enhance the glossiness and beauty of the picture.
Storage and maintenance:
Store oil paintings in a dry and well-ventilated place, avoiding direct sunlight and damp environments.
Gently wipe the picture with a soft cloth regularly to remove dust and stains.
