Hello everyone, Lin Fei to answer the above questions, 550d button description, 550d manual many people do not know, now let's take a look at it!

How to expose correctly?

You should have heard the saying that photography is the art of running out of light. In my opinion, this sentence is very accurate. Photography, or taking pictures, is nothing more than holding a camera. When you press the shutter button, the shutter (the door between the world outside the lens and the photosensitive element inside the fuselage) opens and closes later.

Next, let's take a look at the shooting skills of the Canon 550D SLR camera.

1. How to expose correctly?

First set the camera shooting mode to M, that is, fully manual. If you don't know how to adjust to M, just read the instructions and then you won't explain any more. If you don't understand, read the instruction manual.) Some people say that M is not practical, troublesome to operate, and it is not easy for beginners to master, but I think M is more suitable for beginners to learn, because M needs to adjust circles and shutters manually, and it is easier for beginners to quickly grasp the relationship between aperture and shutter and its impact on imaging. Anyway, I always take M-bit photos as long as I'm not in a hurry.

If you want to take pictures with M file, you must know how to adjust the aperture and shutter. From the LCD screen, there are three data at the top of the horizontal row, the shutter speed on the left, the light intensity in the middle, and the ISO sensitivity on the right. In general, when the light is not very dark, we should set the ISO value to 100. If the light is very dark and you don't want to turn on the flash, you can turn it up properly. Then the aperture and speed are not fixed. It depends on your ambient light and the objects you want to photograph.

Tell me how to adjust the shutter speed in M gear, aperture, ISO. You can adjust the shutter speed by directly rotating the wheel. Press the Av button in the upper right corner of the LCD while rotating the dial to resize the aperture. There is an ISO button on the side of the wheel. Click it, and then use the arrow keys on the back of the machine to select ISO. Once selected, press the SET button in the middle of the arrow keys to confirm. After we know how to adjust it, we will have a practical exercise. First find a doll at home or something like that, take the practice. At this time, you have to practice with your wife. It is estimated that your wife can easily develop photo phobia ~ in general, the best imaging aperture for an 18-55IS lens is 8. First set the aperture to 8. At this point, the setting is aperture 8 ISO 100. After setting, put your eyes close to the viewfinder window, then aim at the subject, half press the shutter, and hear a beep, indicating that the focus is complete and ready to shoot.

In the viewfinder, we can see such a row of green numbers and scales at the bottom. Let's talk about what they mean respectively. On the far left is the speed, the second is the aperture 8, the middle scale is used to test the exposure, and on the right is the ISO100. We notice that there is a small vertical bar under this exposure scale, sometimes on the left, sometimes on the right, sometimes in the middle. The left side indicates underexposure, and the photo taken will be black, the right side will be overexposed, and the photo will be bright. It's best to shoot only in the middle, but it's not absolute. This is just a reference, because different photometric modes and your focus will have some impact on it, but forget about it. At this time, if your light gauge buoy is right in the middle, then you can do it directly. If it is on the right, then you need to accelerate it to 1 canister 160, 1, 200, 1, 200, 250, 1, 320, 1, 400, until the meter is right in the middle. But it is important to note that it is not too fast. If you are shooting a stationary object (including a person whose scene is still), don't adjust it too fast. If it is 1T500 or to the right, you are shooting in a sunny, well-lit environment. At this point, you can stop the speed at 1 stroke for 500 seconds, and then adjust the aperture to turn it down. To reduce the aperture is to increase the aperture value. Then zoom out until the light buoy reaches the middle. If your aperture is set to 22 or to the right, you'd better keep adjusting the speed.

By the way, are you shooting the sun? That's not good. Shooting the sun will burn your eyes and the camera's CCD. If you shoot indoors, the lighting conditions are not good, usually leaving this scale, that is, underexposure. At this point, you should slow down 1ax 100 1max 80 1pm 60 1max 50 1pm 40 1max 30 until the metering scale reaches the middle. If it is to shoot a living person, 1Compact 30 is already the limit. At this time, the photo is easy to blur, because the model can move and her hands will shake. The so-called 1x30 seconds means that after the shutter is pressed, the shutter will be automatically closed after the shutter is opened for 30 seconds, that is, everything that happens in front of the camera within 30 seconds will be recorded in a photo in an overlapping way. If you shoot a stationary object, the speed can be reduced to about a second, depending on whether your hand is stable enough. Take the photographer as an example, if you adjust it to 1 stroke for 30 seconds or to the left, it means your current shooting environment is very dark. Maybe your eyes can still see clearly. That's because your pupils have a very large aperture, and your lens doesn't have that big aperture. At this point, you have to lower the bottom aperture. If the lens is shot at the wide-angle end, that is, the 18mm end, your aperture is 3.5, but the maximum shot effect of the lens is not ideal. So usually use two gears, that is, to 4.5 beats. If the scale is still left after 4.5, it is necessary to increase the sensitivity, that is, to increase the ISO value. Don't think it's not normal, it's normal. Generally speaking, this often happens when there is no sunshine in the room. At present, the speed of the aperture 4.5 recall 1 stroke 30 is still on the left, so increase the ISO to 200. If you don't, it's 400, and if you don't, it's 800. If not, it's 3.5. If not, turn on the flash. If the flash doesn't glow, or if you don't want the flash to blur the light, increase the ISO again. ISO will be adjusted to 1600 3200.

If it doesn't work, stop filming. Where we can't see our fingers, we can't take pictures of them with this camera. Adjust the ruler to the middle and you can do it. After taking a picture, press the play button on the back of the camera to see how it works. If you can't see clearly, press the number button in the upper right corner of the back of the camera to enlarge it. If it feels too bright, let the ruler shoot to the left. If it's still on, keep going to the left. If it is too dark, adjust the ruler to the right. If it is too dark, adjust it to the right. Okay, are you dizzy? Do you think it's difficult and complicated? Don't have the confidence to study? Don't ~ I'm done here, gone, that's all. I am dizzy, take a rest, watch it again, try again, try a few times and become proficient, that's all.

two。 The relationship between aperture shutter speed ISO

This is followed by extended reading.

But why doesn't this happen to human eyes? It will certainly shrink, because if the eyes are too bright, the aperture will be automatically reduced to reduce the amount of light. Turn off the flashlight and see if the pupils are dilated again. This and aperture is the same truth, aperture magnification (that is, numerical adjustment) will see more clearly in the case of bad light, aperture reduction will darken the scene in the too bright light ~ and ISO is like the photosensitive ability of the eye ~ after I know their principle, the slower the shutter speed is, the easier it is to blur, normal handheld shooting should be more than 1/60 seconds. But it's not good if it's too fast for a few 1/1000 seconds. The larger the aperture, the brighter the thing, the smaller the aperture, the darker the ISO, the higher and brighter the ISO100, but normally use ISO100. Because the higher the ISO, the less clear the Tathagata photos. This definition is different from the blur that the shutter is too slow, but the bottom of the picture is rough, so the ISO is usually adjusted to a minimum to take pictures.

3. How to take a picture with a virtual background

Let's talk about how to take a picture with a virtual background. when shooting people, we like to highlight the theme with the effect of virtual background, which is as perfect as the above photo, and the characters stand out very well. For ordinary photographers, you can use this effect to take pictures. If you are traveling to Jiuzhaigou, do not take pictures in this way. The so-called virtual background actually means that the depth of field shot is so small that the scene outside the focus is not clear. The so-called focus is the focus position of the object you want to shoot. Focal length: the distance from your camera to the focus position of your subject is the focal length. Focus: the center of your focus is the focus. Lens focal length: refers to the distance between a group of lenses inside the lens. The smaller the focal length of the lens, the larger the range of view, and the larger the focal length of the lens, the smaller the range of the scene you can see. Focal length: refers to the zoom range of the lens. 18-55 means that the focal head can be changed between 18mm and 55mm.

Lens focal length and aperture are two important factors that affect the depth of field. The larger the aperture, the smaller the depth of field, and the larger the focal length of the lens, the smaller the depth of field. If you want to make it bigger, turn the aperture to the maximum (don't forget that it takes two gears and that's 4.5). The focal length of your 18-55 lens is the focal length of your lens that pulls it to the 18mm end. If you want to shoot the virtual effect, you should focus the lens as much as possible, the bigger the better, your maximum can be set to 55, then shoot with 55, as the lens focal length increases, you will stand farther and farther away from the subject. Then adjust the speed and ISO to adjust the exposure, that is, adjust the position of the buoy of the ruler. Then the background of the photo will vanish. But the virtual effect you take is certainly not as strong as the virtual effect I sent this photo, because the lens is different, to achieve that kind of virtual effect must be the 100mm lens focal length and larger aperture. On the other hand, if you are traveling to Jiuzhaigou to take photos, you can't falsify the background, or go for nothing. At this time, you have to find a way to make the background clearer. This is easy, it is difficult to vanish, it is easy to think clearly, just don't open the aperture so wide, and the background of the aperture above 8 is clearer. Generally speaking, the technique of virtual background should be used as long as there is no good scene without the prospect behind the photographed object.

4. The choice of lens focal length

Let's talk about the choice of focal length of the lens. 18-55mm zoom lens, when the photographer and the subject are fixed, adjusting the focal length of the lens can enlarge and reduce the range of view. Pull the focal length of the lens to 18 when you can take a full-body picture of her about two meters away from the model. But this is not good. When taking pictures of people in mobile space, it is best to take pictures with 50mm or above. When taking full-body photos of characters, they should be taken at a distance of about five meters from the subject. But the head of 18-55 may be a little far away from five meters. Then the four-meter-to-18mm end, that is, the wide-angle end, will deform the subject. For example, if you take a picture of a person sitting in front of you, the legs and feet will become very big, very small, deformed, and unattractive, unless you just want to shoot the artistic effect.

5. How to shoot the night scene

Tell me again how to shoot the night scene. To shoot beautiful lights and buildings at night, you need to buy a tripod. Then use the wide-angle end to shoot, generally when shooting a large range of scenes, the wide-angle end is used. Then the aperture receives 16Di ISO100. The maximum exposure can be set to 30 seconds, and if it is still dark in 30 seconds, then shoot it in another place. There is nothing to shoot in the dark countryside of an old country. If you want to shoot the stars in the sky or just want to shoot the dark countryside, that 30 seconds is really not enough, then continue to tune, 30 seconds down will become the BULB, which is what we call the B gate, this time is no time limit speed, press the shutter button to open the shutter, directly when you release the shutter will be closed. At this time, you can count the time with a watch in your hand. It's okay to drive for a few hours. When I was in junior high school, I photographed Baiwu Comet for three hours with B door. Then when the photo came out a few days later, I found that when my lens was taken, the comet was on the edge of the photo. After a long exposure, the comet went outside the viewfinder. It's too late for everything. At this time, the comet is long gone, and the next time we shoot Baiwu comet will be 20 million years later. I don't think I can wait until that time. Depressed, ah, at that time, if you had a digital camera, you could directly see whether it had been shot or not.

In addition, when using door B to take pictures, you also need to get a shutter line in addition to the tripod, which is usually 30 yuan. If you don't have a shutter line, you'll have to hold your hand on the shutter for two hours, and no one can stand it. Even if you can stand it, holding your hand on the shutter will definitely shake, affecting the photo effect. Therefore, it is necessary to use the shutter line, even if the exposure speed is a few seconds, it is better to use the shutter line, because the camera will blur the picture when you press the shutter, which is the most obvious from the exposure time to the exposure time of 30 to 5 seconds. If you shoot with a tripod without a shutter line, you can set it to selfie mode to take pictures. Another point to remind is that if you use a tripod to take pictures, it is best to use the view window cover to prevent the extra light from entering the camera. No, that's it. This time it's really gone, and the rest is slowly groping for itself. in addition, what we still need to learn at this time is the theoretical knowledge of scene composition, which must be learned. if you have time to look for this kind of articles on the Internet, you can do it.

6. How to focus when the subject is not in the middle of the picture

With regard to focusing, there are three ways to focus, which is a single AF artificial intelligence focusing AF artificial intelligence servo AF, which is different from my SONY, mine is a single self-continuous, I usually use a single AF, Canon's other two focus modes I have not studied. The so-called single AF is to start focusing when you half press the shutter, and enter the focus lock state in front of you when you release the shutter. At this time, no matter how you move the camera, you will no longer focus. This is very useful when the subject is not in the center of the picture. When you take a picture in which the subject is not in the center of the picture, aim the subject in the center of the picture first, and then press the shutter halfway. After focusing, don't release the shutter, then move the camera composition to put the subject in the position you want, and then press the shutter completely to take the picture. The 500D has multi-point focus mode, but I usually don't use it. I only use the center point, because the center point is the most accurate, and it is more troublesome to choose other focus. So that's how I focus.

7. How to take portraits outside in the dark

Again, if you shoot people in the dark sky, if you shoot people in brightly lit urban buildings outside at night, you must use a flash, but in general, if you shoot a person directly with a flash, the person will shoot brightly, but it will be dark all around, and you can't get the lighting effect of the surrounding buildings. At this time, you have to slow down. When you take a picture with a flash, the aperture is usually 8, and then you can slow down to a second or even a little slower. Don't worry about shaking hands to make people empty, because people have already been photographed at the moment of flash, and if you shake your hands for an extra second, there will be a small double image, but it doesn't matter. Then adjust the flash mode of the flash to slow synchronization, so the effect is that the characters are illuminated by the flash and shoot very clearly, and the lights of the buildings behind can also be combined with the lights of the long-term exposure. If the flash mode is still dark in a second, then increase the ISO appropriately. In addition, when using the flash, we should pay attention to the limited distance of the flash, do not be too far away from the subject. Finally, I would like to sum up a few laws: ISO has a great influence on picture quality, so you don't have to use high ISO. The shutter is usually placed at 8 to take pictures, and if you want to falsify, you can all 8, and then use the shutter speed to adjust the brightness. When shooting with a tripod, if it is still too dark at 30, you can only improve ISO. If you shoot immobile objects with a tripod, long-term exposure will also affect the picture quality. But no matter how long the exposure time is, the picture quality is better than that of high ISO. When the light is too strong, such as shooting outdoors on a sunny day, it should be suitable for reducing the aperture (that is, increasing the aperture value). These are just references, not absolute, but when you can't find a reason to overturn these laws, continue to follow them until you have your own ideas.

8. How to take dynamic car photos

Shooting this dynamic car ~ the picture looks very dynamic, the car in the picture is clear, the background is the effect of wind speed, and the wheels are rotating. This kind of picture is relatively easy to take. Shooting method: set the shutter speed to 1max for 15 seconds, and then adjust the aperture slowly according to the shooting ring mirror. Then stand on the side of the road a little further away from the car, 18-55 lens will be shot with 55mm, and then stand about 10 meters from the road, adjust the focus mode to [artificial intelligence servo AF] mode, which is suitable for shooting objects with a wide range of movement, such as cars, boats, birds, people running, etc. ~ in this mode, the lens is in continuous focus when the shutter is half pressed. After adjusting the shutter aperture and setting the [artificial intelligence servo AF] focus mode, wait for the car to pass by, aim at it as soon as the car passes by, and then focus the center of the viewfinder on a fixed part of the car, and then the body keeps following the car as it moves, and press the shutter to take pictures when the car is directly in front of you. One trick is not to follow the car when it is directly in front of you, but to move with the car at the moment of shooting and follow the car while keeping the camera level. Try and practice several times over and over again, mainly for the stability of the hands and the speed of following the car. Ideally, the car is very clear, and the trees and buildings by the side of the road form the wind speed effect. If you have a high success rate, you can try to lower the shutter to 1 beat 10 seconds and try again. If it is always unsuccessful, try to practice slowly with 1jump 20 1top 30.

But this is just taking pictures of other people's cars, and no one can guarantee a 100% success rate, so how do you shoot a particular car if you want to shoot it? It is also very easy, for example, if you want to shoot a car A, you need a person to drive another car (B car) to cooperate with you, you sit in the passenger seat of the B car, and the B car runs side by side with the A car at the same speed, and then the shutter 1max 15. At this time, because the two cars are close to each other, then you have to shoot with wide angle, which is not difficult, because the two cars are driving side by side, you can shoot whatever you want. At this time, it is best to let the A driver open the window and focus on the driver. If the A car is handsome, then take the car as the main shot. Be careful not to take pictures while driving.) Q: why do I try all kinds of exposure and shooting methods when I take pictures, but I can't get the effect of a master? A: taking outdoor photos depends on the time and season as well as the weather. For example, Qingdao can't take a good picture of the distant scenery in summer, but it can wait until winter or late autumn. When shooting outdoor portraits, the light on cloudy days is softer and the effect is better. Backlight photos should be taken in the morning and evening in the spring, autumn and winter when the oblique sunlight is not very strong. Shooting the night scene every night is the best when it is just getting dark and not completely dark. At that time, the effect of the blue sky can be photographed, the lights in the city are all on again, and the buildings and lights as well as the blue sky can be photographed. Shooting sunrise and sunset also depends on the cleanliness of the air. So if you want to take a very good picture, you have to take any picture at any time. It is difficult to take a portrait outside on a sunny day in summer at noon.

9. How to take ghost photos

Taking pictures of such ghosts needs to be taken in an environment where the light is very dark, but the human eye can still see things clearly. I took this picture in the hallway of the hospital. The shooting method is also very simple. I need a tripod. My picture is a selfie ~ this method can either take a selfie or take a picture for others, first let the subject be in a good position and then focus, and then turn off the autofocus switch of the lens after focusing. The shutter speed is set to 30 seconds, ISO100, the aperture depends. If you are taking a selfie for yourself, choose a ten-second delay selfie, press the shutter and run to the front to pose and wait. when you hear the sound of the shutter shooting, keep the body motionless and keep the shape for ten seconds, and calculate some time in your own mind. as soon as the time comes, change the position and change the shape and then remain motionless, the faster the speed of change and shape, the better, and then change the shape after ten seconds. In this way, the final picture will be the effect of my picture. If the shadow in the idle photo is too light, then don't pose for 15 seconds, it will be clearer. It doesn't matter if the light is dark around you. If you use shutter line B, you can run over and turn off the shutter when you feel that the exposure time is almost up. But be careful not to rush to the lens when closing the shutter. Close the shutter from the side of the camera. Because of the dim light, the action of you running back to close the shutter will not be reflected in the photo. In addition, in the case of taking pictures of such long-term exposure instead of shooting city lights at night, the photos exposed for a long time will be partial to color, usually yellow, and the color temperature should be set lower at this time. If you are taking a raw photo, you can use the color temperature in the later period.

10. How to take silhouette photos

To take a picture of this silhouette effect, you need to choose before the sun comes out completely in the morning or before the sun sets in the evening. This photo is found on the Internet, and it is a good shot, but the problem is that the sun has already set. Although the blue sky and sunset are more beautiful, but the shutter speed is not fast enough, there is a shadow, and it is troublesome to turn up the ISO. Therefore, in the early practice, it is more suitable to practice before the sun fully rises in the morning or before the sun sets in the evening. Shooting method: let the subject dodge first, and then focus on the brighter places near the sunrise or sunset to adjust the aperture and speed, and then try to take a picture to see if the photo exposure is appropriate, a little darker, just not too bright, try to let the model stand in front of the camera to block the sun, and then take pictures, this is the silhouette effect. When taking this kind of photo, we must pay attention to the exaggeration of the shape of the character. If it is still the same as usual, then no one can tell whether it is a person or an oversized condom. It's good to take pictures like running sideways or riding a bike on your side. in addition, the camera position for this kind of photo is lower, which means it is more effective for the camera to be closer to the ground.

11. How to shoot fireworks

There is no fixed data for shooting fireworks, because different types of fireworks, different places, different shooting distances are all different. Roughly speaking, generally speaking, it is necessary to have a tripod and shutter line, and the camera is fixed. Then turn off the autofocus button on the lens, push the focal length to the right place, and set the focal length to infinity if it is more than 15 meters. Then set the shutter speed to door B. Hold the shutter line in hand, then press the shutter when you hear the gun, release the shutter when the fireworks are finished, and then watch the shooting effect, narrow the aperture if the fireworks are too bright, enlarge the aperture if it is too dark, and increase the ISO when the aperture is still dark at the end. If you want to shoot the effect of letting a hundred flowers blossom, people who set off fireworks have to hold down the B door one by one and hold the lens cap in hand. As soon as the fireworks fly into the sky, take off the lens cap, and then cover it again as soon as the fireworks are burned. Then continue to press and hold the B door and wait for the second fireworks to rise to the sky and then open the lens cap. If you shoot fireworks in the background of bustling urban lights, then you need to take care of the exposure of the lights of the background city.

12. How to take pictures at the wedding

When you have a SLR, a friend will get married and ask you to take pictures. It is not easy for you to take this kind of photos when you do not have a big flash, because wedding photos do not allow failure, and you must know that the exposure is correct. So at this time, you have to ensure that the shutter speed is above 1max 60, and the aperture is appropriate. If not, you can improve ISO. There is no other good way. In addition, usually the camera is hung around the neck, but the wedding is different, you need to wrap the camera strap around your wrist, this is because there is a toast to the wedding, we can't squeeze in when people drink, and it's hard to take pictures. I usually take pictures blindly with the camera above my head. In addition, it should be noted that wedding photos are all racing shots, at this time can not use M file, it is better to use Av file.

13, how to shoot to show a, how to shoot to show thin, which angle is the most beautiful.

Generally speaking, it is more obvious to shoot from the bottom to the top in the low position, but the previous question is that if the subject is a woman with thick legs, then you can't shoot like this. The tip of the chin is shown from top to bottom, and if you have a big belly, you can block it with your hands or not take a picture of the whole body. Everyone's face is different, so everyone has their own most beautiful angle. Some people are suitable for laughing while others are not, so you have to observe and see more before taking pictures. First, you can see which angle the subject looks good at.

At the end of this article, I hope it will be helpful to you.
