How does iPhone take a nice selfie with the rearview mirror beside the car?

Hello, pay attention to skills when taking pictures. When you use a digital camera or SLR, sometimes there will be some biased effects, so you need to master some skills when taking pictures of people. 1, shoot from the line of sight, and look at your subject from the line of sight. Direct line-of-sight removal can make photos closer to life. When shooting people, keep the camera at the height of the human eye to show charming eyes and beautiful smiles. Bend over when patting a child. The subject doesn't have to keep looking at the camera. Shooting from the eye height will have a personal charm effect and make the photo more attractive. 2. Use a simple background. A simple background can highlight the subject better. 3. Use flash outdoors. Strong sunlight can cast a nasty shadow on people's faces. You can use a flash to illuminate your face to eliminate shadows. On cloudy days, you can also use no flash, and sometimes the soft light effect of darkness will produce better results. 4. When taking a selfie, be sure to put the camera in a stable position, such as a flat stone or tripod, and aim at the shooting position first. Don't shake the camera when you press the shutter, so as not to take the wrong angle. 5. When operating the selfie, remember to press the shutter behind the camera, not in front of the camera, because when you press the shutter, the focal length will be locked, so the focal length is wrong. 6. The third method is also the most widely used, that is, holding a selfie. It is no exaggeration to say that this is the king of selfies. This method needs to pay attention to the key points. Generally speaking, the camera held by the outstretched hand is about 5 ~ 60 cm away from the selfie taker, which is a troublesome distance. Depending on the camera, "macro mode" is sometimes used. If you use an ordinary camera, pay attention to the left and right sides of the selfie, which are contrary to your usual habits. If you press the shutter with an unaccustomed hand, you should pay attention to controlling the hand shake. Including various control buttons, also need to be adjusted. If you use a camera that can rotate the lens (such as Sony F88 or Pentax Optio X). ), you don't have to change your usual habits. 7. There are basically three poses for holding a selfie: bottom-up shooting, frontal shooting and top-down shooting. The feelings of these three postures also have different changes. If you shoot from the bottom up, it will give people a mature feeling. If you want to film yourself, you must grasp it. That's what it feels like to shoot from bottom to top. Very mature feeling. Shooting from top to bottom feels young and lively, and it is also the most commonly used posture. Frontal shooting is generally dull, and you can add some small expressions and props. Self-portraits are not limited to the front. Turn your body slightly and change all kinds of expressions from a slightly inclined angle. A little effort can bring unexpected changes to the photos you take. 8. At present, 6:00-9:00 am is the best shooting time in summer, because at this time, the sunshine intensity is soft and the height is moderate, and the portraits taken will not have strong shadows, and there is no lack of three-dimensional sense in the sun. Sunset is also one of the best times to shoot portraits, but due to the high temperature of nearly 40 degrees, it is generally difficult for models to play normally, so early morning is the prime time for outdoor portrait shooting in summer. 9. For the choice of location, try to choose a simple and sparsely populated place. Parks and green spaces are one of the simplest choices. Open-air bars with rich cultural atmosphere and western-style modern architectural scenes are also good choices. If you like a wide field of vision, then suburban green space is the most suitable. 10, for the choice of focal length, for portrait photos, it can usually be divided into several common modes: full body, chest circumference and face close-up. Generally, these modes can be combined with the composition mentioned above to take an ideal portrait photo. However, one thing worthy of beginners' attention is the choice of focal length. A reasonable focal length can reflect a stronger sense of space and three-dimensionality, while the wrong use of focal length may make your beautiful model's face flat or lack the layering of photos. When shooting full-length and bust, you can't blindly pursue the beauty of blurred background, and directly pull the optical zoom of 10 times in your hand to the end. Although this can give you a certain small depth of field, the negative effect is narrow, which is the feeling of spatial vision. This is because when shooting with telephoto, the angle of light entering the lens is very small, and only a small piece of scenery behind people can be photographed. Therefore, the standard focal length of about 50 mm should be selected for full-length photos, and the telephoto of 135 to 200 mm or more should be used for half-length and local close-ups. Common zoom lenses of 50mm, 85mm and 70-200 are commonly used portrait lenses, and different lenses have their own characteristics in horizontal and vertical composition. But for ordinary photographers, vertical composition is more suitable for portrait shooting, because vertical composition can make people occupy a larger area and better show the facial details of the model. Oblique composition and diagonal composition are also one of the common portrait compositions, which can highlight the movement more than before. 1 1. In order to avoid false photos, you can also increase the sensitivity of digital cameras, and perhaps you can use films with high ISO values. However, it should be noted that the increase of ISO will lead to the problems of image coarsening and noise increase. Generally speaking, the sensitivity of amateur cameras and digital cameras cannot exceed ISO400, otherwise it is difficult to obtain ideal image quality. 12, portrait shooting, in the backlight environment, sometimes pure silhouette can be used to express the outline and lines of the characters, forming different interests. The so-called silhouette is a scene in which the subject is completely black or nearly completely black and the background is normally exposed. Practice: 1, switch the metering mode to "spot metering". 2. Take the scenery behind the portrait, such as green trees, as the basis of metering (get the combination of aperture and shutter). After metering, press the camera's automatic exposure lock button to lock the exposure value. 3. Then adjust the composition and shoot with the exposure combination just now. 13, when shooting portraits, no matter what light source is used, as long as it is in front of the subject and has enough brightness, it will be reflected into the eyes, and there will be reflection points, thus forming a vision. The reflection points displayed in the eyes are always different in shape, size and position. For example, when shooting a portrait indoors, the light shines from the window far away from the subject, and a bright window shadow will appear in each of his eyes; Using the flash on the camera will produce tiny white spots in the center of the eyes; When a reflector or umbrella is used, a reflection area will be formed, which is usually biased to one side. The effects of various eye lamps vary greatly. Small bright light is pleasant, wide light is soft, and unlit eyes are like deep pools. British photographer Gordon. Anderson pointed out that in order to shoot excellent portrait photography, we must consider the light of the eyes before pressing the shutter. Let the subject look up slightly or rearrange the light sources to determine whether he has a vision. Eye light should be balanced, one eye should not have light, and the other eye should not have light. It is necessary to check whether the light source that produces eye light is located in front of the subject's face, enough to illuminate his eyes without being blocked by the shadow of his nose. If the head turns to one side, it is better for the eye light source to rotate with it. The position of the light source should not be too high, otherwise the two eyes are not on a horizontal line, and one eye may not shine. The light source used as eye lamp does not need strong power, but it must be in harmony with the environment. Anderson believes that personally, he would rather choose natural light as the light source for his eyes. If you are indoors, it is best to use the light from the window above your shoulders to make eye light, even if it is not the main light source. Outside, it is much more natural to use a reflector than an auxiliary flash, especially when taking close-up photos. Also try to avoid the white eye reflection on the main light source, which can only emit tasteless white light, which will make people's eyes lose balance. 14, don't shoot all the people on the screen, it will be dull, and proper composition and cropping will reflect people's characteristics, such as slender legs. Therefore, a better method is to break the balance between face and body with a long focal length and keep a certain distance from the subject. Using DC, you can observe the composition effect on the liquid crystal display and talk with the subject to eliminate his nervousness and show his nature as much as possible. In the case of some backlight indoors, it is necessary to forcibly turn on the flash to fill the light. Because the shooting distance is different and the brightness to be supplemented is different, the appropriate flash intensity should be selected according to the specific needs. 15, wide-angle lens is usually used for landscape shooting. As mentioned above, portrait shooting usually uses a long focal length, but in some cases, using a wide-angle focal length can achieve a sense of presence that telephoto does not have. When it is close to the face, proper deformation may bring unexpected effects. Shoot with a wide angle from below, highlighting the slender legs. Use a wide angle and take a close-up close to your face. I hope these personal experiences will satisfy you.
