I will give you a detailed analysis of the capturing photography skills of the Canon 50D camera.
Tips:
<Shooting data>
Camera: EOS 50D
Lens: EF-S 18-55mm f/3.5-5.6 IS
Automatic aperture first exposure
(F5.6, 1/80 seconds)
Exposure compensation: + 1EV
White balance: Automatic
ISO 400
Photo Style: Standard
Step 1: Use positive exposure compensation to make the face brighter
When capturing a photo, if the main subject is a person, you can think that the exposure tendency should be the same as when performing portrait photography. When determining the impression, the subject should be the face of the person to avoid the average brightness of the screen. + 1EV exposure compensation was adopted for the image obtained from the real-time display of the video during this shooting. Although the degree of compensation varies depending on the situation, when the legend shows a white wall as the background, the overall exposure is usually slightly biased towards underexposure. Visual effects should be prioritized to determine the final brightness.
Step 2: Use ISO sensitivity to compensate for shutter speed reduction caused by exposure compensation
When positive exposure compensation and automatic aperture exposure are adopted, the shutter speed is certainly reduced. Even if the shutter speed IS reduced to a certain extent, the static object can be compensated by the hand jitter compensation mechanism (IS), but if the object IS a person, we still hope to maintain a certain shutter speed. The goal of this shot is to take natural relaxation photos of a female in real-time face mode. In order to capture her smile and expression, the ISO 400 sensitivity was selected. In addition, the shutter speed is increased to 1/80 seconds considering the aperture value. Compared with ISO 100, shutter speed is improved by about two levels, which is more conducive to shooting.
Step 3: place the support under the camera to ensure stable composition
In order to use the real-time display and shooting face-first real-time mode, while chatting with the person sitting on the opposite side, a foam plastic simple unit is placed under the camera. This ensures the stability of the diagram and prevents hand jitter. You do not need to purchase equipment that is used as a fixed platform. Using the products around you is enough. For example, using a cake box or a thick book will also play a good effect. However, you cannot use items that may damage the bottom of the camera or lens or that are easily slide by the camera. You can try to use various materials.
Step 4: capture characters in face-first real-time mode
Select the face-first real-time mode when the video is displayed in real time. In face-first real-time mode, the camera can automatically detect the face of a person. A white focus box appears on the screen of the LCD monitor to keep track of the position of the person's face. It is not as limited to the focus position as it was when shooting with an optical viewfinder, so it is basically able to detect the face of a person within all the ranges of the screen. As shown in the figure, even if there is an obstacle between the camera and the character, the face of the character can be correctly detected, which is reassuring. While observing the facial expression of a person, you can capture the opportunity without using the scene recorder.
Step 5: enable auto focus and release the shutter
When a natural expression appears in a conversation, you can use auto focus to focus on it and enter the preparation phase. After the focus is completed, as shown in the figure, the white focus box turns green, and a "very bright" sound will be triggered, even if you do not observe the scene, you can grasp the focal state at any time. After focusing, if you feel that the character is moving, you can start auto focus again, repeat the focus, and finally finish shooting.
Key points:
Focus is done by the camera and focus on the characters and expressions. The most important thing is to prevent the shooting object from realizing the existence of the camera.
The face-first real-time mode completely subverts common knowledge about SLR cameras. In the past, SLR cameras used the difference detection autofocus sensor to focus, mainly pursuing focus speed and accuracy, the face-first real-time mode brings the new "degree of freedom" to focus performance. It is not limited by the focus position and quantity. It can automatically track the face of a person and take pictures of the person in any scenario. Because you do not need to raise the camera to the eye height, you can take a more natural look. In the Focus speed aspect, although the face-first real-time mode is indeed less than the combination of the optical viewfinder and the difference detection autofocus sensor, it has an outstanding advantage in freshness and fun. As long as you constantly sharpen your technology, you can take a fresh and ideal photo. You can not only take a picture from the waist as shown in the legend, but also take a picture from a high angle or a low angle.
Advanced Skills
If you want to have a higher portrait depth, you can use a wide-angle zoom lens to highlight the sensation and take a novel photo. Here we use the 16mm side of EF 16-35mm f/2.8L ii usm to zoom in the front of the wine glass and bouquet, and get a very unique photo. You can use an ultra-wide zoom lens, an "EF 15mm f/2.8 fish eye" lens, and other lenses, as well as beyond your imagination.
All right, the above information is the full content of the analysis and sharing of the capture photography skills of the Canon 50D camera for photography enthusiasts, I believe that you are now very clear about photography skills, so all users will follow the tips above to capture their wonderful life.
