How and what is the function of lines in a sketch still life?

In sketching still life, how and what lines do is a crucial part of the painting process, helping to convey the shape, structure, and texture of an object. Here are some basic principles and functions of lines in sketching still lifes:

How to draw lines:

Contour Line: Traces the outer contour of an object and is used to define the shape and edges of the object. Contour lines are usually strong and can be emphasized with heavier lines or the intersection of lines.

Construction lines: Used to depict the structure and shape inside an object. Construction lines can be lines that connect parts of an object, helping to establish proper proportions and perspectives.

Guides: Guides are used to aid in positioning and proportioning during the drawing process, helping to draw the main features of an object.

Shadow Edges: Lines are used to outline the transition edges between shadows and light and shadow to enhance the three-dimensional effect of the form.

The role of lines:

Defining the shape: Lines help the viewer understand the overall shape of an object by depicting its contours and structure.

Establish perspective: By constructing lines and perspective lines, you can accurately express the distance and spatial relationship of objects in the picture, enhancing the sense of realism.

Emphasize important parts: Lines can be used to emphasize key parts of an object, making the viewer pay more attention to the important points in the picture.

Create emotion: The shape of the lines and the way the brushstrokes are stroked can express emotion and atmosphere, making the picture more expressive.

Heighten Layering: Using lines to depict transitioning edges between shadows and light and shadow can help add depth to objects and give the picture more depth.

In sketching still life painting, the use of lines needs to combine observation and artistic sense, and through delicate line expression, the picture is more vivid and artistic.

The included still lifes are: porcelain jars, bananas, apples, pears, mangosteens, green peppers, table lamps, cabbage, geometric plaster statues, gouache tools, plates, interlinings, etc.

Two tips for drawing a good sketch still life.

1. Learn composition. The picture is full, rich in layers, and the main and secondary are clear.

2. Depiction skills. For example, when painting porcelain and stainless steel still life, the highlights will be solid, and the plastic and interlining surface of the rough still life will be blurred in the highlights.

Sketch classification. 1. Sketching in terms of purpose and function; Generally, it can be divided into two categories: creative sketching and study sketching.

2. Sketching is divided into still life, animal, landscape, portrait and human sketch in terms of content.

3. SketchingFrom the perspective of painting tradition, sketching can be divided into two types: Chinese freehand traditional sketching and Western realistic traditional sketching.

4. SketchingFrom the concept of painting time, sketching can be divided into long-term sketching, sketching, silent writing, etc.

5. Sketches are divided into pencils, charcoal, pens, brushes, ink, chalk, paper pens or sketches interspersed with two kinds of tools.

There are many references to sketch still lifes, such as bottles, jars, and all kinds of fruits, such as apples, oranges, pears, etc., as well as various daily necessities, such as books, lamps, tables, etc.

Still lifes commonly used in sketching include ceramic jars, goblets, glasses, linen tablecloths, and plastic plates of various fruits, such as apples, pears, and grapes.

Commonly referenced still lifes for sketching are jars, plates, bottles, apples, pears, plates, bananas, oranges, plaster still lifes, and a variety of interlinings.

1. Parallel straight lines: The lines of parallel straight lines are straight, and the density of the lines is used to reach the effect of light and shade on the surface.

2. Crossing straight lines: Straight lines crossing together is a cross straight line, which is also to reflect the brightness and darkness of the surface, and the practice of crossing straight lines has a certain sense of picture, which can also be called the practice of the picture.

3. **: Generally reflect a short picture, such as eyebrows, pay attention to the arrangement must be regular, and prohibit chaos.

Fourth, zigzag line: is the Z-shaped line, more difficult than the straight line, mostly used in flat painting, smearing and other painting methods, suitable for soft, smooth, without too much texture of the object.

5. Arc: The arc is the line with curvature, such as the eyes and the face shape, and the line curve is arc, which will be expressed by the arc.

6. Circle line: Draw irregular curves at will, different curve combinations can be used to express different texture effects, for example, curly hair is very suitable for this kind of line.

In sketching, the most basic requirement for a line is "two ends of the void, the middle of the solid", that is to say, when the pen should be light, the middle should be heavier depending on the situation, and then light, although there is light and heavy, but we must strive to achieve the effect in one go, do not hesitate, such a pen is convenient for the lines to connect with each other, there is room for modification, and the overall picture effect is better.

The lines arranged together, that is, "lines" are used to express different aspects in sketches, and the way of expression is more flexible and rich, generally speaking, there are parallel lines, overlapping lines, staggered lines, turning lines, etc., we must learn to use them flexibly. The ultimate goal is to combine countless irregular lines together to present a perfect work according to the actual situation.

In painting, keep in mind that there are two kinds of lines that cannot be drawn: one is the line with two ends, and the other is the line with a hook. For beginners, these two situations often occur, and the consequence is that not only will there be a more obvious interface between the lines, but also the lines will appear chaotic in the picture, which will eventually affect the overall picture effect.

In short, if you want to use the lines well in sketching, it is not a day's work, and you must keep these precautions in mind in the daily practice process. That's all there is to know about getting started with sketching: what to pay attention to when using lines in sketching.

Sketch Basics. Drawing is the foundation of all plastic arts, and it is the basic means of practicing painting. Michelangelo said

Drawing is the source and essence of painting, sculpture, architecture and other types of painting. And it is the foundation of all science, and those who have mastered this technology can believe that they have a great fortune.

Classification of sketches.

1.In terms of purpose and function, it can generally be divided into two categories: creative sketching and study sketching.

2.In terms of the tools used, it is divided into pencil sketches, charcoal sketches, pen sketches, brush sketches, ink sketches, chalk sketches or sketches interspersed with two tools.

3.In terms of painting time, it can be divided into long-term sketching, sketching, slow writing, etc.

4.In terms of depiction content, sketches can be divided into gypsum geometric body sketches, still life sketches, gypsum head sketches, gypsum half-body sketches, gypsum full-body sketches, character head sketches, character half-body sketches and body sketches.

Fundamentals of pen holding. Horizontal grip.

The barrel of the pen is placed between the three tips of the thumb, index finger and middle finger, the index finger is in front, the finger is behind the left and the middle finger is in the lower right, the index finger should be lower than the thumb, and the tip of the finger should be about 3 cm away from the tip of the pen. Keep the barrel and the workbook at an angle of 45°, the palm is rounded, and the knuckles are slightly bent.
