Oil painting is a painting made of quick-drying vegetable oil (linseed oil, poppy seed oil, walnut oil, etc.). ) mixed with pigments on canvas linen, cardboard or wood. Acrylic painting is a kind of painting made of acrylic pigment. This pigment is a new type of painting pigment which appeared in the 1960s. It is a mixture of chemically synthesized latex and colored particles.
Acrylic painting and oil painting belong to the category of color painting, and their differences mainly lie in their characteristics, textures and techniques.
In terms of characteristics, the color of oil painting can be very thin, transparent and translucent, or very thick, with strong hiding power and adhesion, and can be covered and coated in multiple layers for a long time. The forms and techniques of oil painting are also very rich and varied, which can be large or small, thick or thin, thin or thick, permeable or impermeable, flexible and changeable.
Acrylic painting can be said to be a kind of "plastic", which is easy to dry and needs careful preservation. After drying, it is a flexible film, which is firm, wear-resistant, water-resistant, corrosion-resistant, naturally aging-resistant, colorfast, non-deteriorating, non-reflective, and easy to wash after painting. It is suitable for easel paintings, indoor and outdoor murals, etc. In terms of texture, oil painting is rich, heavy, calm and shiny; Polypropylene painting is flexible and changeable.
The difference in technique is that oil painting can show all the modeling and visual features of an object in a very concrete and meticulous way-that is, it can reproduce the light-color relationship, light-dark level, physical structure, spatial sense and texture of an object in a specific time and space, so that the image of the picture can reach an extremely realistic level.
There is no clear composition in acrylic painting, but attention should be paid to the procedure when painting, so that the strokes are naturally connected and the composition is cautious to achieve the desired effect.
The difference between acrylic painting and oil painting
Acrylic painting and oil painting are two common painting media, and they have some obvious differences:
1, drying time: acrylic painting is a quick-drying medium because its pigment is basically composed of water and acrylic resin. It can be dried in a few minutes to several hours, depending on the thickness and humidity of the pigment. On the other hand, oil painting needs a longer drying time, usually a few days or even weeks, because its pigment contains oil.
2. Color change: The acrylic pigment hardly changes color after drying. Their colors are very stable and will not change significantly. However, with the passage of time, some subtle changes may occur in oil painting pigments, especially the oxidation and yellowing of colors.
3. Values: The colors of acrylic paintings are usually bright and clear, and they can keep their original appearance even after drying. The colors of oil paintings are layered, and more details and textures can be created through superposition and fusion.
4. operability: acrylic coatings can be changed and covered before and after drying, and can also be mixed with other media. This makes it easier to modify and adjust the acrylic painting. In contrast, oil painting pigments are difficult to modify after drying, which is relatively more difficult to handle.
5. Taste and solvent: acrylic paint uses water as diluent without strong solvent. This makes acrylic painting relatively tasteless and friendly to the environment and human health. However, oil painting pigments usually need diluents such as linseed oil or mineral oil, which will produce some special smells and need to be used with caution. The workplace is well ventilated.
Choose acrylic painting or oil painting, depending on personal preference, painting purpose and desired effect. Acrylic painting is suitable for artists who work fast or like to finish their works in a short time, and oil painting is suitable for works that pursue depth, hierarchy and luster.
