How to capture Canon 50D?

Canon 50D does not use a viewfinder, and the way to capture natural people is as follows: lt; Shooting data gt; Camera: EOS 50D lens: EF-S 18-55mm f/3.5-F5.6 IS aperture priority automatic exposure (F5.6, 1/80s) exposure compensation:+1EV white balance: automatic ISO 400 camera style: standard step/kloc- When determining the exposure, people's faces should be the main body to avoid averaging the brightness of the whole picture. According to the image obtained from the real-time display shooting picture, exposure compensation of+1EV is adopted. Although the degree of compensation varies from case to case, the overall exposure is usually slightly underexposed when a white wall is used as the background in the legend. Visual effects should be given priority to determine the final brightness. Step 2: Use ISO sensitivity to compensate for the decrease of shutter speed caused by exposure compensation. When positive exposure compensation is carried out and aperture priority automatic exposure is adopted, the shutter speed will of course decrease. If shooting a still life, even if the shutter speed IS reduced to a certain extent, it can be compensated by hand shake compensation mechanism (IS), but if the subject is a person, it is still desirable to keep a certain shutter speed. The goal of this shooting is to shoot a naturally relaxed woman in real-time mode with face first. In order to capture her smile and expression when she speaks, the sensitivity of ISO 400 was selected. Considering the aperture value, the shutter speed is increased to 1/80 seconds. Compared with ISO 100, the shutter speed is increased by about two levels, which is more conducive to shooting. Step 3: Put a bracket under the camera to keep the composition stable. In order to adopt the face-first real-time mode of real-time display shooting, we talk to the person sitting opposite while shooting, and put a simple foam plastic fixed platform under the camera. This can ensure the stability of composition and prevent hand jitter. You don't need to buy electrical appliances to fix the table, just use things around you, such as cake boxes or thick books, which will also have good results. But don't use things that may damage the camera or the bottom of the lens, or things that make the camera slide easily. You can try to use various materials. Step 4: Catch people in face priority real-time mode, and choose face priority real-time mode when shooting in real time. In face first real-time mode, the camera can automatically detect faces. A white focus box will appear on the LCD monitor screen to continuously track the position of the person's face. It won't be limited by the focus position like when shooting with an optical viewfinder, so it can basically detect faces in all areas of the picture. As shown in the legend, even if there is an obstacle between the camera and the person, the face can be detected correctly, which is reassuring enough. While observing the expression of the characters, you can capture the snapshot opportunity without using the viewfinder. Step 5: Auto focus and release the shutter. When natural expressions appear in the dialogue, you can use autofocus to focus and enter the stage of preparing for shooting. After the focus is completed, as shown in the figure, the white focus frame will turn green, and at the same time, the ldquo Hey rdquo prompt sound will be issued, so that the focus situation can be grasped at any time even if the viewfinder is not observed. After focusing, if you feel that people are moving, you can start autofocus again, repeat focusing, and finally finish shooting. Focus: Focusing is done by the camera, focusing on the expression of the characters, and the most important thing is not to let the subject realize the existence of the camera. The real-time mode of face priority completely subverts the common sense about SLR cameras. In the past, SLR cameras used phase difference detection autofocus sensors to focus, mainly pursuing focusing speed and accuracy, while face-first real-time mode brought ldquo to focusing performance. The degree of freedom rdquo is a brand-new performance index. It is not limited by the focus position and number, and can automatically track the face and shoot people freely in any scene. Because there is no need to raise the camera to eye level, you can take a more natural expression. In terms of focusing speed, although the face priority real-time mode is not as good as the combination of optical viewfinder and phase difference detection autofocus sensor, it has advantages in freshness and interest. As long as you constantly sharpen your skills, you can take refreshing and ideal photos. You can shoot people not only from waist height as shown in the legend, but also from high or low angles. Advanced skills If you want to make the picture have a stronger sense of depth, you can use a wide-angle zoom lens to emphasize the sense of perspective and take novel photos. Here, the 16mm end of EF 16-35mm/2.8L II USM is used to enlarge and image the wine glasses and bouquets in front of us, and a very unique photo is obtained. Not only can you use a super wide-angle zoom lens, but you can also use ldquo. EF 15mm f/2.8 fisheye rdquo and other lenses can also get unimaginable effects.
