At the sight of the picture he liked, the contemplator thinks about what impressed him precisely in the work. But the most interesting thing is how the artist himself was able to draw attention to his work. And this task is carried out using visual techniques that are used to convey mood, atmosphere, realism and the idea itself. The most important thing is the ability to see your work whole. With this, the artist is helped by gradations of light and shadow, which allow him to represent all the objects depicted at the same time and distribute them into plans and groups.
Tonality in art
In order to understand the role of black and white gradations, which also include glare and reflex in painting and drawing, it is worth understanding the general scheme of the image of volume. All techniques in the creation of visual art originate from the word “tone”, which in Greek sounds like “tension”. But most often it is not a color tone, but a light one. This is due to the way the light behaves, changing the local color of the depicted object depending on the lighting itself and its environment.
Together with a simple line, with a variety of colors that allow the artist to portray his plan, tone is one of the main techniques. It is the laws of tone that help craftsmen to convey the texture, shape of objects, the impact on them of the environment and airspace.
What is valer
Light divisions of a hue or color in a tone are called valers. Their levels begin with white and end with the darkest shade of color. Changing these levels depends on how much white or black is added to the local color. But, despite the fact that this sufficiently reduces the effect of brightness, valers are very important in the visual arts. Thanks to the levels, a point is created that attracts attention, the effect of deep space, integrity and, most importantly, volume.
Grisailly paintings show the importance of understanding Valera. In such images, gray and other neutral tones are used, with which it is easier for the artist to determine the main gradations of light and shadow - glare, partial shade, shadow, light, reflex - in painting and graphics.
The role of shadows in painting and drawing
Shadows on the depicted object show poorly lit or not lit areas. They can be divided into their own and falling. Poorly lit areas on the surface are called their own shadows, and the darkness that casts an object is called falling. The shadow that appears under the influence of low light from several sources is called penumbra.
In painting, the shadow changes depending on what kind of lighting. If it is naturally warm, then the shadows will be cold, and with artificial light they are warm. These gradations in interaction with light allow us to depict the connection between light and shadow - chiaroscuro. But it differs from tonal valers in that it is subject only to optical laws, and not to the imagination of the artist. In other words, depicting chiaroscuro on an object, the artist relies on specific lighting, and when creating the overall picture, using tones, he achieves integrity in favor of composition, which is slightly different from real vision.
The role of light in painting and graphics
From the light source depends on how the artist will be able to convey the shape and volume of the necessary objects. And the light itself encloses space in its laws, which are distributed in the airspace and are felt on the surfaces. Light appears on the surface of an object under direct rays. Under his influence, not only the most ordinary materials and textures are changed, but also glossy surfaces. If the latter is convex or flat, a glare forms under a direct ray of light. Using glare is much easier to transmit reflective material due to the general connection of objects in the painting with a color reflex and other gradations of light and shadow.
The role of the reflex
The reflex in painting and graphics demonstrates the connection of objects among themselves and their influence on each other, which gives integrity to the work. It is formed in the shadow due to the rays that fall on a nearby object, and shows its reflected light. That reflex complements the work of the artist.
In nature, everything is not always perfect and correct, because objects are combined into groups and plans. Residents of paintings are painted with special attention directed to their surroundings. The feeling of airspace is created by the impression of secondary objects, which occurs when studying the first plan. Among the fallen autumn leaves, you can see the greenery, which comes from the still-withered grass. These reflexes in the painting of nature add a special color and atmosphere to the picture.
Reflexes and other gradations of light and shadow change depending on the lighting. The same view from the window shows all its bright and dull colors for the whole day, which resembles a film that changes the mood of the viewer.
