Where are translucent objects used?

Question 1: Where are transparent, translucent and opaque objects used in daily life? They are everywhere.

Question 2: What color is the background color of transparent objects? I don't know what you mean by transparent object, and under what circumstances you should give it a background color. Here, I can only talk about my own views from the perspective of general aesthetics for your reference.

1, general rules. This is from the color itself. Because transparent objects are easy to "absorb color", dark backgrounds should be avoided. For example, a beautiful glass or a set of cool pot cups is placed on a table covered with a black tablecloth. Their elegant shape and crystal clear quality are greatly reduced visually, but the effect is very different when placed on a table covered with light blue, light green, goose yellow, pink and other colors.

2. The principle of contrast. This is from the perspective of brightness. If you put some transparent objects in a dark place, you should not only follow the "general principles", but also consider "contrasting background colors". For example, you can put some transparent cups on the table top of a pink tablecloth, and you can pad a pale yellow tray or a pale blue square towel to highlight transparent objects.

3. The principle of coordination. This is from the perspective of the environment. For example, the wallpaper around the room is close to white, so the background color is blue, and the wallpaper is close to bronze, so the background color is goose yellow.

4, the principle of particularity. This is "good-looking" under special circumstances. For example, if this transparent object is given to your lover, you should choose rose as the background color, for your peers, you can choose light yellow or golden yellow as the background color, and for your elders, you can choose blue or bronze as the background color.

These are some reference principles. Different people have different experiences, different tastes and different aesthetics, and they will have different feelings about whether they look good or not. For your reference, I certainly hope it will help you.

Question 3: What determines the colors of transparent and opaque objects? The color of a transparent object is determined by the color of light passing through it. The color of an opaque object is determined by its own color, and it will reflect light of the same color as itself.

Question 4: The color of a transparent object is determined by its light. It seems that your expression is not very standard It should be like this:

1, the color of transparent body is determined by the reflected light. That means: all transparent body hits on its surface, which can't pass through, but can only be reflected. After the reflected light enters people's eyes, we will see. Therefore, the color of transparent body is determined by the color light it reflects. In addition, transparent body can only reflect its natural color light and absorb other colors. That is to say, whatever light transparent body is, it can be reflected.

2. The color of transparent body is determined by the colored light passing through it. It means that when light strikes its surface, the color of transparent body depends on what color it can penetrate. In addition, colored transparent body can only transmit natural color light and absorb other colors. For example, yellow glass can only penetrate yellow light and absorb other colors to make the room warm; Blue glass can only transmit blue light and absorb other colors to make the room cool. Colorless transparent body can transmit all colors.

I hope it helps you.

Question 5: How to shoot transparent things It is troublesome to shoot transparent or mirror objects for 20 minutes. When shooting transparent, translucent and reflective objects, the photographer should not only consider the object itself, but also consider everything around, because the shooting result depends largely on the surrounding environment.

When you light transparent glassware with a lamp. You are actually illuminating the background behind it. Translucent objects can reflect colors on the background and colors on the foreground. A mirror object can reflect everything in front of it, including lights, cameras, tripods and even the photographer's own images.

One approach is to use a special soft mask to surround the main body. Usually this soft mask is made of white paper stretched on the frame. Translucent plastic paper can be easily used to make three-dimensional soft mask. When the spotlight is directly hit on the plastic soft cover, the objects in the soft cover will be illuminated by the scattered soft light. Adding a color acetate film filter in front of the lamp can also enhance the effect of a certain color.

Sticking proper black paper on the soft mask can deepen the dark part of the main body and help to carve its shape. Where reflection is needed, make a hole in the soft mask to let the spotlight light enter directly.

If the soft mask is permanent. You can hang it on the ceiling of the studio when not in use. Another method is to paint the whole studio wall in non-reflective white, which is very convenient for high-profile lighting. When you don't need high-profile photos. The temporary walls are made of seamless colored cardboard, and the white ceiling is used to reflect soft top light. Such a studio is most suitable for flash photography.

In addition, there are some non-professional skills that can also be referenced:

Question 6: How to draw transparent objects is too serious. Hehe, we art students need to communicate more.

First of all, most people don't like to draw transparent objects, such as empty cups or cups filled with water. After drawing the background, draw the outline with different shades of lines. This kind of painting is simple and relaxed, giving people a feeling of dripping with joy.

The above is the method of most students. If you like, you can try my own method. (For reference only): I think everything that is transparent is separated by layers, so I will choose to draw the background first, empty the space in the glass, and then draw the background inside the glass with a deeper background color, which is more realistic. I drew it during the exam. Of course, I also like the method of drawing the outline directly, which has its own advantages and disadvantages.

But pay attention to the texture when drawing transparent objects. Don't draw glass objects too many times, just like plastic. The same is true when it comes to white. Although glass reflects a lot of light, it can't be full of light, and the highlights should also have changes in depth and temperature.

As for the sketch mentioned by Qin, I think Qin must have a lot of experience, so it goes without saying that it is too basic. I'm just saying that I think we should pay attention to the art exam.

For the exam, I think the work should be eye-catching, so there should be a clear relationship between black, white and gray, not too gray, and the relationship between black and white should be opened; Of course, the type should be accurate; You are not allowed to draw backgrounds and projections during the exam. . In that way, the space will be represented by virtual processing, and the picture should have a relationship between reality and reality; To create a three-dimensional or something. . That's about it. .

And gouache: I think we should pay attention to it during the exam: every teacher teaches in a different style. My teacher teaches the kind of paintings with big color blocks and bright colors. Be able to stand out from the crowd in the exam, just like sketching, pay attention to the context, and the background should be separated from the main object. If still life wants to be bright, it must have dark part, transition part and bright part, which is the same and clear. Be strong in shaping. Although color is a painting color, it must have its own color, and projection is also very important, so it must be suppressed. Fruits are painted with solid colors to make them look bright. According to the growth structure, I personally prefer works with large strokes. Looks happy. . .

I think we should pay attention to the exam. . . That's all. I hope I can help my parents.

Relax in the exam and face the challenge calmly. I believe you will be admitted to the ideal school!
