Dear Students, Hello everybody, today's programs come with you to discuss the basic composition. Before class, the teacher asked students to keep up a concept, the so-called composition, and there is no "absolute" iron law, we can actually choose their favorite way to be. Today we taught the way of several composition is generally take pictures of the basic method, students can follow to try and then it extends out to find their own favorite composition choice.

Figure 5-1
1. Photographic composition is a "subtraction" work

First we have to understand is that thinking in the photographic composition is, in fact, a "subtraction" of the work, we take pictures, use live camera view window to capture images of Peter, the next step must be to filter out the screen do not need. By forward and back, changing the lens focal length, and then to the subject in the picture frame.

Most mistake people made in the photograph is when the problem is easier, is take too many "junk" on the screen, while the Dodge the importance of the topic screen. Especially when using wide-angle lens to take pictures, because of the wide angle too easy to come in with your irrelevant things, this error will be particularly vulnerable. Sometimes pictures are too greedy because once too many topics you want to capture the screen, but lost the focus to entire photo.

Figure used in the example of a 35mm lens, through close to the subject (the little girl and hats) way to take pictures, use"subtraction" concept does not need to remove the debris outside the theme, the theme of the whole picture can be more prominent.

2. Shoot theme complete a whole is the most reliable way

Use of "subtraction" concept to composition, in fact, accumulated experience is need to do, minus the stuff on the screen which requires students to take the time to experience a lot of pictures. If you talk about subtraction, then capture the subject's body gave off, that is one of the most reliable and most stable way.

Figure II examples are retrieved the girl's body in the picture, and placed her on the center of the screen, clear the performance of the theme will be apparent, this is the safest and most simple composition approach. Another little girl's head in a little space left, you can create a sense of stability, so that the focus falls on the screen below this point the students may wish to clap for himself to see, try to stay space and leaving no room for differences.

3. The subject filled the whole screen

Make a picture full of the subject fully present, do not join the other debris, the composition is a very lovable way. Because only the theme of the picture appears, there is no interference with other items, so the whole picture makes quite clear expression of ideas.

Figure III screen will be four little girls were tucked inside the border, let the other things there, the students use the same idea can only take a face, a flower or even an eye to performance.

4. The appropriate blank, you can add mood to the screen

Discussed above, filled with pictures, in fact, the appropriate blank, you can have that kind of mood for photos, so viewers have other imagination. Rather monotonous in the background or not a complex environment, you can use this approach, narrow the theme of the space in the picture, while not necessarily want to be placed in the center of the subject, and sometimes this can make the theme even more eye-catching performance

Figure IV only a picture of little girl left half of the screen, leaving the right and the space above, together with a comparison chart, showing the charm is not the same as

Figure 5-5.
5. Fixed blank line is considered the location of one of the conditions

Turning blank, then blank to remain in what position, is a very interesting question. There is a simple way to determine that we can use the theme of "moving line" to determine the location of blank space.

What is the action line? In Figure V, for example, this picture is a little girl to see the direction of the eye as a moving line of reference, the little girl's eyes look to the right, so the decision to put the location of blank in the whole right side of the screen. As a reference point to this extension, students can also be based on the body's contours, lines, objects move forward to determine the location.

The way this choice should be obvious prerequisite is the theme of the dynamic line, the average still life in this way may not be used to determine. Teachers have always thought that blank with the "feel" very relevant, students may wish to try to blank with their own feelings, take lots of pictures, see more performance of different mood.

6. Prudent decide to cut the position of the theme

We take pictures when the subject will not necessarily show the full, sometimes cut out some parts, as we have a way to express the theme. Cutting theme by the need for good thinking, because the way if cut properly, tend to undermine the coordination of the whole picture.

So how do we choose can make a coordinated performance? This branch of learning is very extensive, not that we can talk about beginner's class finished, so the teacher in this, the first shot as an example to the characters.

Pictures of people cutting the biggest taboo subject, is to cut border joints in the figures (such as the neck joints, wrist joints, leg joints, the waist joint, etc.), the composition of the line as long as the cut in the joints, it will make people look a "broken" feeling.

Example in Figure Six, the students try to get a piece of paper, cover the joints in the subject closer look, you will understand what the teacher said.

Composition of today's examples the teacher show  figures that people have more context photographic composition to be found, things will not be too complicated to consider the other to simplify the picture, this example is to color the background to shoot. Students tried to make this point of the curriculum taught to extend, thinking to see if other subject of a composition problem. Teachers will have the opportunity to invite other ideas people for landscape photography to talk about specifically for the composition problem is landscape photography.

Also answer a letter kaiwei raised about the issues , he referred to "how to decide the fast to shutter, and aperture value with the number? We usually how to combination of them?"

First, before the teacher asks everyone to take a variety of aperture, shutter speed according to the test is to know the different aperture, shutter to shoot images of what the situation awareness, we can take the theme according to demand, to determine the aperture shutter value.

When photographing a habit, that is, before you pressing the shutter choose to use the "Aperture" or "Shutter Priority." So-called "aperture priority", "Shutter Priority" is the decision taken under the condition that the aperture-based, or shutter-based.

for example"aperture priority",we wanted to make a character theme and the background blurry photos, then we will be choosing a large aperture (for example, decide aperture f2.8), determine the aperture value, began to test light, adjust the shutter using the numerical approach, to complete the metering setting action.

Now for example "Shutter Priority",we want to turned the waterfall into a silver-white, like satin, then we will be choosing a slow shutter speed (for example, the shutter set at 1 / 4 seconds), the decision shutter value, began to turn the aperture value to match the metering.
students should be able to understand it, involves the depth of field aperture, shutter speed value of the performance involved, according to "Aperture Priority" or "Shutter Priority" we need to decide the change in value to another to form metering action.
