How does Canon 50D take portraits?
Canon 50D shoots soft portraits with the help of window light as follows: lt; Shooting data gt; Camera: EOS 50D lens: EF 50mm f/ 1.2L USM aperture priority automatic exposure (F 1.6, 1/320 seconds) White balance: automatic ISO 200 photography style: standard steps 1: Fix the camera on a tripod for better use of brightness. Although the window light injected through the curtain looks strong, the actual amount of light is relatively small. And the indoor background is often complicated. In order to blur the background and simplify the composition, a soft and bright fixed-focus lens should also be used. However, in order to use a bright fixed-focus lens to approach the aperture value of the maximum aperture, more accurate focusing is needed. For real-time display shooting, the camera needs to be firmly fixed on the tripod. Step 2: Turn off the indoor lighting to prevent color cast. When the light from the window is the main light source, be sure to turn off all indoor lighting to prevent color cast in the shadow. The part illuminated by outdoor lighting is brighter than indoor lighting, and it is not easy to appear color cast. Although the light through the curtain is very soft and easy to use, it also has the disadvantage of absolute light, and the shadow part is easily affected by indoor lighting, which must be paid attention to. It is difficult for the human eye to distinguish the deviation of the optimal tone, but digital cameras will faithfully reproduce the color difference, so we must be very careful. Step 3: Let the characters stand facing the window and make maximum use of the light. It is best to stand as close to the window as possible. In addition, you should make the characters' faces face outward to ensure the light irradiation, which is the trick to shoot this scene. Doing so can make soft light shine on people's faces smoothly and ensure that people's skin can be imaged delicately. And standing in this position can let the light enter the eyes of the characters and get more vivid expressions, which can be described as killing two birds with one stone. The key point is to regard the whole window as a big light source, so that people's position and face orientation can be determined naturally. You can choose the intensity of light shining on a person's face according to your personal preference. It is best to let the light pass through a white curtain made of translucent thin cloth such as lace, which can illuminate a person's skin ideally. However, it should be noted that light passing through colored curtains will cause color cast and is not recommended. Step 4: Adjust the ISO sensitivity according to the light intensity. After basically determining the standing position of the person, check the exposure of the camera. In order to improve shutter speed and avoid subject jitter, ISO sensitivity should be improved. Set the aperture value of the lens to F 1.6 here. Considering the subtle movements of characters and eye movements caused by blinking, ISO 200 is chosen. The shutter speed used is 1/320 seconds. The optimal shutter speed depends on the focal length of the lens used. Because portrait photography is different from still life photography, people's actions need to be considered, so even if the camera is fixed, regardless of the focal length, the shutter speed should be at least1125 seconds to ensure peace of mind. Step 5: In the starting real-time display shooting picture, use manual focusing to point at people's eyes and move the zoom-in box. Make the zoom-in frame consistent with the center of human eyes, press the auto-focus point selection/zoom-in button, and use the zoom-in display of 10 times to accurately focus the depth of human pupils. If there is no big movement of the character, you can also keep the enlarged display and release the shutter directly. Every shot does not return to the normal display. Because the depth of field is shallow when the aperture is near the maximum aperture, people can be required to keep still, keep the rhythm and cooperate with each other in shooting. Key points: To give full play to the characteristics of bright fixed-focus lens, we must take every photo carefully, not continuous shooting. So far, it is not as simple as described in the language to skillfully use bright fixed-focus lenses to take ideal portrait photos. The reason is that focusing is very difficult, and even an excellent phase difference detection autofocus sensor cannot guarantee that it can focus on the same position every time. If you use the optical viewfinder for manual focusing, if you are not very skilled, it will greatly increase the number of failed photos. But with the appearance of real-time display shooting, this situation has been improved. When using a bright fixed-focus lens, the focusing operation becomes extremely simple, and anyone can easily complete the focusing. In order to avoid the influence of focusing deviation, the method of narrowing the aperture was often used in the past, but now it is not necessary to use this method to complete precise focusing, and the imaging characteristics of the bright fixed-focus lens itself can be better played when shooting. Although the shooting rhythm is slightly inferior to the phase difference detection autofocus, the method of real-time display shooting plus manual focusing is superior in focusing accuracy. You can choose the appropriate focusing method according to the aperture of the lens used and the shooting purpose. Advanced skills The reflector, which is often used when shooting portraits outdoors, should actually be actively used when shooting indoors. Reflecting the light from the window and making up the shadow can get a more beautiful effect. The legend photo was taken with the mirror as close as possible to the left of the model. It is very convenient to confirm whether the reflector enters the picture because the field of view of the real-time display shooting picture is 100% of the actual image.
