What should I pay attention to when learning photography from scratch?

Starting from scratch, I don't know what camera you use, so I have to take the card machine as an example. I hope the landlord can benefit from it: 1. How to enjoy or take photos?

A good photo has three elements.

Theme, theme, choice.

1. What is the theme of this photo?

2. How can we focus on the subject and attract the attention of the viewer?

3. Is the picture concise? Does it only include things that are conducive to attracting the attention of the subject? Have you missed every unnecessary content that distracts you?

Taking pictures is like writing an article. First of all, we should be clear about what topics we want to express, such as feelings, artistic conception and so on. The second is to choose a theme and express your ideas through a theme. Therefore, the topic selection is very important. Most of the photos taken by novices have no subject, that is, they simply don't understand what the main things (or people) are in the photos. There's no point.

Weighing is to get rid of things that affect the performance of the subject. One of the biggest mistakes for beginners to take pictures is to take pictures of everything they see and put everything they see into the lens. It seems that many students write articles and talk nonsense. Write for a long time, and write a lot of useless things/irrelevant to the theme or topic. One of the greatest skills of photography is simplicity, not simplicity. The picture is simple, but the artistic conception is endless.

Second, about the choice of camera.

1. First of all, if the camera can be small and keep good imaging, I believe that professional SLR cameras and lenses don't need to be large. So the smaller the camera, the better. The bigger the better.

2. About pixels. Many people care about pixels. In fact, the bigger the pixel, the better. The key is the size of the image sensor. Generally speaking, the larger the CCD and CMOS, the better the imaging effect. Of course, the lens is also important, but the lens of the card machine is not very good So the area of CCD and CMOS is more important.

3. At present, the CCD and CMOS areas of the card machine are 1/3, 1/2.5,11.7,11.6,1/. Of course, the bigger the better. A large CCD means low noise. High quality.

4. As for zoom parameters, small zoom is recommended, and large zoom imaging is often not as good as small zoom.

Third, focus.

Press the shutter half (not all), and the camera will prompt you to focus. The focus prompt of card machine is usually represented by a rectangular box. This is the clearest part of the whole picture. However, the focusing function of the card machine is very limited, and the effect is often very general. It is recommended to focus with its center. That is, you can only focus on the central point. If you want to compose a composition, move the focus to a place other than the center, first press the shutter halfway, and then move the camera in the focal plane after the center is focused. Note: Move the camera in a plane parallel to the focus, and do not deviate from the plane. For example, when shooting people, they usually focus on the eyes, because the eyes are the windows of the soul, so the eyes need to be the clearest. Focus can be used in both automatic and manual situations.

Four, automatic and manual

Cheap fool machines generally do not have the function of manual control. Or only have some manual functions. A camera with full manual function will be more expensive. But the effect will definitely be better. Because machines are not people, no matter how clever they are, sometimes they can't achieve the expected results. Automatic gear is generally represented by P, and the camera is generally on the round wheel above. But different cameras are different. Still need to read more instructions. Manual gear is generally represented by m, so it is recommended that you use the full manual function to shoot.

As for automatic shooting, there is nothing to say. So mainly talk about manual operation/

Fifth, full manual shooting.

1, ISO setting. Now camera manufacturers have been preaching how high the highest ISO of their cameras is.

But I suggest you try to shoot with the lowest ISO. ISO is a digital camera that imitates the film design of a film camera. The lower the ISO, the less noise and the better the picture quality, so try to use the lowest ISO in case of sufficient light. But low ISO faces a problem. The lower the ISO, the slower the required shutter speed. So when the light is poor, it will shoot too slowly because the shutter speed is too slow. So if the light is too dim to shoot, we should improve the ISO. Step by step until your hands don't shake.

2. White balance. The color discrimination of digital cameras is different from that of film. The film camera does not need to adjust the white balance. Therefore, the effect of digital camera shooting often deviates from the actual color. So there is the adjustment of "white balance". Methods: Enter the white balance setting and adjust it manually. Point a blank piece of paper at the light. Then press the shutter. Yes, when you see the paper in the camera is white. If the color is deviated, readjust it, sometimes several times.

General professional photography uses a gray card. I always try to shoot with gray cards. But for friends who use card machines, there is no need to have that thing. It is also very accurate to use white paper instead.

Manual white balance setting is generally suitable for scenes with single light. For example, outdoors during the day. Manual white balance is useless in scenes with very complicated light, such as night scenes. It's better to use automatic.

3. Aperture and shutter.

A slightly higher-end card will provide manual aperture and shutter settings. Or "aperture priority". "Shutter priority" function. Because the card machine can't get shallow depth of field, it is difficult to blur the background. In fact, any aperture is similar. There is not much difference. Generally speaking, a large aperture is suitable for close-ups. Blur the background and highlight the subject. Small aperture is suitable for shooting large scenes. Because the card machine can only get large depth of field. So these differences are not very big.

Aperture values are generally represented by F2.8, F3.5, F4, F5.6, F8, 1 1, f16,22. The larger the number, the smaller the aperture. For example, the set of aperture values I mentioned above. F2.8 is the maximum aperture. F22 is the smallest aperture. A large aperture means that the larger the transparent aperture, the more light will be incident.

A large aperture can get more light. So if you think the shutter speed is too slow to hold, you can open the aperture. But the bigger the aperture, the better. The aperture with the best imaging effect is generally F5.6-F 1 1.

Sixth, simple composition skills.

Many people like to use the center composition. Actually, that's the most unsightly. The simplest and most practical composition technique is the golden section composition method.

That is, when writing a composition, put the subject in a little more than one-third.
