First, it is easy to draw. For "four fingers", because "it is easier to draw than five fingers", the traditional two-dimensional animation used to draw one by one, requiring 12 to 14 frames per second. Reducing a finger can simplify the structure of the hand, and in most cases, the effect and influence of the opponent are very small, thus making the picture more concise and reducing the workload. Because painting with five fingers is really more difficult than painting with four fingers, especially in the era of hand painting and pure manual work, it is really understandable to draw characters from different angles to form coherent movements, and it is really understandable to save pens. You can imagine how much time you can save. When the animated character moves.
Second, after five fingers move, they look like six fingers, which is caused by optical illusion, so at that time, the animation industry generally thought that drawing four fingers was just right. For example, Disney first designed a portrait of Mickey Mouse with five fingers, and then it was a tragedy. Finger images look like banana claws. Please imagine Mickey Mouse waving two bunches of bananas in your mind. So, cut off a finger
Three or four fingers are cuter, because cartoon characters will look cuter if their fingers are fatter, and they will look wider and more crowded if they draw five fingers, so they usually only draw four.
Fourth, lovely and observant relatives at home must know that cats, dogs and other animals generally have four fingers, such as meow. There are four obvious fingers in the front paw, and the fifth finger is hidden in the forearm, which is very sharp. Its main function is grasping, and its hind paw is four fingers, so it is probably the result of the observation of the animator.
This truth needs no explanation. In real life, our five fingers and thumb are the most indispensable, and the little finger is the most useless. Needless to say, in Comic World, cute cartoon animals can complete their tasks only by exaggerated expressions and body movements, and even fight with the heroic black cat sheriff of gangsters every day, successfully arresting criminals with four fingers in each hand.
