Commodity image
Product image is the expansion of animal personification in the field of goods, and anthropomorphic goods give people a sense of intimacy. Personalized modeling has a refreshing feeling, thus deepening people's direct impression of goods.
classify
As far as the idea of commodity personification is concerned, it can be roughly divided into two categories:
The first category is complete personification, that is, exaggerating goods and using the characteristics and modeling structure of goods to personify performance.
The second category is semi-anthropomorphism, that is, adding hands, feet and heads unrelated to commodities as anthropomorphic characteristic elements.
The above two anthropomorphic molding technologies make the goods humanized and personalized. Through the form of animation, emphasizing the characteristics of goods, its actions and words are directly related to goods, and the publicity effect is more obvious.
Illustrators often draw illustrations for graphic designers or directly for magazines, newspapers and other media. They are generally professional illustrators or freelance artists, and have their own themes and painting styles like photographers. Their professional sensitivity and desire for new forms and tools have led many of them to use cg animation design tools to create illustrations. The software function of Cg animation makes their creative talent play a greater role. Whether it is simple or complex, whether it is traditional media effects, such as oil painting, watercolor, printmaking style or the endless new changes and new interests of digital graphics, it can be completed more conveniently and quickly. Digital photography is the latest development of photography. Photographers shoot objects with digital cameras or scan traditional positive films into computers through scanners, then adjust, combine and create new visual images on computer screens, and finally output positive films or negative films through film recorders. This brand-new photography technology has completely changed the creative concept of photographic optical imaging, taking digital graphics processing as the core, and is also called "darkroom photography". It blurs the boundaries between photographers, illustrators and graphic designers. Nowadays, as long as they are talented, they can complete all three tasks on the same computer.
How to learn hand-drawn illustrations on a zero basis? First, set the theme.
As the saying goes, everything is difficult at the beginning. At first, we should set a theme. We can use a specific theme to give a direction to creation, so that the threshold for starting is lower and we will not give up at the beginning. Later, I began to try abstract themes. Find your favorite theme and make yourself more motivated. Daily necessities, office supplies, transportation, food, plants, animals, things that can be touched immediately around, and so on.
Second, composition
There are many ways to compose a composition. If the composition is suitable for the theme or the content conveyed, then the composition will affect the presentation of the theme.
Third, color matching.
In fact, it is very interesting to match complementary colors or contrasting colors. As long as the proportion is well distributed, great achievements can be made. All the colors in the picture are not evenly distributed, let alone compare the depth, chroma and lightness of the colors. But think about these colors. What color will they go with? The more conspicuous it is in the contrast relationship, the smaller its proportion will be.
Fourth, the atmosphere, feelings
After trying several times to create and practice, start to follow your feelings! Sometimes you can try to create aimlessly, draw whatever you want, and it's fun to combine or violate the physical principles! At this time, we should boldly inject more imagination. In fact, in the later stage, you can draw whatever you want, sometimes it's just a feeling, or an unspeakable feeling, or a picture in a dream.
The above is the related content of hand-drawn illustration. Today I want to talk about the practice of illustration design direction. With visual design, we can create illustrations that conform to the style and dedicate them to you who have a design foundation.
How do marine animals sleep? Marine animals are the general name of heterotrophs in the ocean. There are many categories, and the morphological structure and physiological characteristics of each category can be very different. Tiny single-celled protozoa, big whales can be more than 30 meters long and weigh more than 190 tons. The following is how I carefully recommend marine animals to sleep, for reference only, welcome to read!
How do marine animals sleep?
Both humans and animals need sleep. If we can't get a good sleep for a long time because of external interference, we and animals will be physically and mentally exhausted and even die. People usually lie down and sleep, but animals sleep in various ways-birds, such as herons, storks, cranes and snipes, can stand on one foot, canines, such as wolves, dogs and jackals, need their ears to stick to the ground, bats can hang their bodies upside down, and spiders and monkeys can hook their tails directly on branches. So how do animals sleep in the sea?
Although animals in the ocean sleep in different positions, most of them sleep for a short time due to the double pressure of breathing and natural enemies, which is difficult for human beings to find.
Fish can never close their eyes because they have no eyelids, so they all sleep with their eyes open. In order to keep breathing, the gill cover will still flap slowly and rhythmically, and occasionally paddle the pectoral fin or caudal fin to keep the body balanced. Fish sleep like a human nap, some only for a few minutes, and some even only for a few seconds, mainly because they must always be vigilant, otherwise they will fall into the mouth of the sneak attacker.
Dolphins seem to swim around in the water all day and have no time to sleep. In fact, their schedule is similar to ours. At night, the dolphin will dive 30 meters underwater and fall asleep quietly, but its tail will still swing every 30 seconds or so. But dolphins belong to mammals. How do they breathe when they sleep? It turns out that the dolphin has a huge lung capacity and oxygen can be stored in its blood, so it can no longer surface within a few minutes after a breath, which is enough for it to have a beautiful dream. Of course, dolphins stay alert when they sleep. Scientists have found that the two hemispheres of their brains sleep alternately: when one side is asleep, the other side is awake. After a while, the two will exchange again. If stimulated by the outside world, both hemispheres will wake up at the same time to ensure that they can respond quickly to external changes.
Seals are different from dolphins. They can live underwater or move on shore. If they choose to sleep on the shore, they are similar to land animals; If you choose to sleep underwater, you will wake up every time you breathe. Although it seems uncomfortable to us onlookers, they are used to it.
When the octopus sleeps, it will leave two tentacles scratching around its body, and the rest will be rolled up to rest. If two active tentacles are disturbed by the outside world, they will wake up immediately.
Manatees like to sleep at the bottom of the sea, but unlike dolphins and whales, they can't hold their breath underwater for a long time. Manatees will surface for a breath in about 10 minutes, so their "good dreams" are hard to connect.
Seals are much smarter. They either sleep on land or put their noses out of the ice hole to breathe when sleeping, and their bodies float vertically in the water, which looks like an upright sculpture, which is convenient for breathing and does not delay a deep sleep.
Marine animals sleep in a really different way.
Why do some plants "walk"
A botanist made a scientific investigation in a deserted place in the western United States. When he left, he chose a special plant and marked it so that he could find this place next time. However, a few months later, when he returned there, he found that the plants were gone! The careful scientist carefully observed the surrounding situation and found a shallow trace on the ground. Following this trail, he walked a long way and finally found the marked factory by a small lake. Plants can walk by themselves?
It turns out that this plant can grow in a fixed place with enough water. Once there is drought and water shortage, its roots will leave the soil and the plant will roll into a ball. When the wind blows, it will move with it. When it meets water, it will stop, insert its roots into the soil, get water and nutrients, and start its new life. Because this plant seems to be able to perceive the surrounding environment and wake up from a deep sleep, people call it the awakening tree.
There is also a plant in the desert called tumbleweed, which can roll its roots into a ball and roll with the wind when it is dry. Seen from a distance, it looks like a fast rolling ball. Where there is water, it will take root and sprout.
Why are there no three-legged animals?
There is such a record in Shan Hai Jing Huang Da East longitude: "There are six waves of mountains in the East China Sea, which reach 7,000 miles into the sea. There is a wild animal on it, which looks like a cow. It is pale and has no horns. When you step into and out of the water, there will be a storm. Its light is like the sun and the moon, and its sound is like thunder. Its name is Kui. The Yellow Emperor got it, with its skin as the drum and the bone of Lei Shou as the guide, and it was famous in the world for 500 miles. " This legendary ancient mythical beast is actually an animal with only one leg.
Legs are the motor organs of animals. In reality, snails crawl on one leg, frogs, lizards, leopards and elephants jump, crawl and walk on four legs, while humans, bats, birds and extinct pterosaurs have two legs. However, no matter how hard you rack your brains, it is estimated that you can't list which animal has three legs. The reason is probably related to the evolution of organisms.
At the beginning of life, a cell is a life. After that, life composed of multiple cells began to appear on the earth, such as sponge, the most primitive and lowest multicellular animal. Although some sponges have certain shapes and symmetry, most of them grow irregularly like plants, forming asymmetric body structures such as flat, round and dendritic. Then coelenterates began to appear, such as jellyfish. Their central axis (from mouth to mouth) has many sections, which can divide their bodies into two equal parts. In biology, organisms with this form are called "radiation symmetric organisms". They can only be divided up and down, not around. They can only be fixed in the water or float with the current, passively taking food from the surrounding environment.
Later, in order to gain the initiative, a class of animals suitable for swimming and crawling appeared. To do this, their bodies must be clearly divided into front and back, left and right, and back and abdomen. Morphologically, only one symmetrical plane (or section) passes through the central axis of the animal body, which can divide the animal body into two equal parts. This kind of animal is called "bilaterally symmetrical animal" or "bilaterally symmetrical animal". This change from non-directional movement to directional movement makes animals adapt to a wider range, which is a more advanced evolutionary form than radiation symmetry.
There are many animals with symmetrical sides, such as mollusks such as snails, mammals such as humans, leopards and elephants, amphibians and reptiles such as birds, frogs and lizards, and insects such as dragonflies and locusts. As the name implies, when they are reflected in the number of legs, they are either 1 (which can be divided into two) or even numbers such as 2, 4 and 6, otherwise they are not symmetrical in shape. So a three-legged animal can't exist on a line that is symmetrical on both sides.
So, is it possible to appear in radiation symmetric organisms? In an animal called five-radial symmetry, there are indeed five-wrist starfish that can move slowly. According to this inference, you might suggest that there should be a kind of "some kind of starfish" with three legs, but unfortunately it has not been found so far. Moreover, fundamentally speaking, this kind of fixed or floating creature with passive motion actually has no real "leg" structure.
Perhaps, in the long evolutionary history of life, there have been three-legged animals. It is only a great pity that this animal has not been found in living or related fossils. As for the three-legged animals occasionally seen in news reports, it is because of the deformities formed by environmental and genetic mutations, and there is no way to stably pass them on to the next generation.
