How to take a good photo, the camera should be set like this first.
Texture is the sensory judgment of an object through its surface presentation, material and geometric size. The texture of a photo is the details and levels of the picture. For example, the coldness and hardness of steel, the softness and warmth of silk, the toughness of cowboys and the silky silk scarves are all manifestations of texture.
Want to take a textured photo is also related to factors such as light and depth of field.
1, light. Light is in the hands of a photographer, just like a brush in the hands of a painter and a carving knife in the hands of a sculptor. The formation of texture is composed of countless different points, lines and surfaces. How are countless points, lines and surfaces formed? It's light. Light outlines points and lines through light and shade, and shapes the texture and details of the picture through soft and hard. It can be said that the texture of photos is mostly determined by the light. In fact, it is a question of how to choose light and how to choose light distribution.
Select the appropriate light texture according to the texture of the object. There are two kinds of textures here, don't confuse them. Let's talk about the first one: the texture of the object. Leather goods are hard and plush toys are soft. Second: light also has texture. Direct light is hard, such as the sunshine at noon on a sunny day, with great contrast and shadow; The skylight on a cloudy day is very soft, with almost no contrast and no shadow. Choose the texture of the light according to the texture of the object. Such as: hard objects (steel, leather goods, cowboys, men. Wait. ), then the light is best to choose hard direct light. If the object is soft (silk, gauze, children, girls, etc.). ), then it is best to choose broad and soft light, such as scattered light and transmitted light. If artificial light is used indoors, the standard cover belongs to hard light and the soft light box belongs to soft light. When soft light is selected for natural light, you can shoot in shadows or cloudy days.
2. Light level: that is, the position of the light source relative to the subject. Imagine the shape of a clock, with the main body in the middle and the photographer standing at 6 o'clock. When the light source is at 5 o'clock or 7 o'clock, the angle with the camera is 30 degrees. The greater the angle, the greater the contrast and vice versa. Moreover, different light levels have different performances in the texture of the picture (of course, this is not the only reason). For example, a large angle has a stronger texture and is suitable for shooting tough objects; When the included angle is small, the texture is weak, which is suitable for shooting soft objects. If the left-right angle exceeds 90 degrees, it belongs to side backlight and backlight. At this time, it is necessary to have an auxiliary light source in front to supplement the details and levels of the dark part.
Backlight is a very good way to express texture, but it needs light in front to express dark details. That is to say, the light ratio (light-dark ratio) should be controlled. Obviously, the photo of the subject does not add details to the front, so the light ratio is too large, and many details are missing (seriously underexposed), let alone the texture.
3. Depth of field. Among them, the depth of field is of great significance to the clarity, artistic treatment and expression of the theme image of the picture. It is often overlooked by people. For example, when shooting poorly, the depth of field is too large, and the clarity of the foreground and background in the picture can be seen, which leads to the confusion of primary and secondary images. The picture has no focus, so there is no theme.
