How Canon 5D Mark II flexibly uses fuzzy photography to photograph portraits.

Canon 5D Mark II flexibly uses blurred portrait photography techniques as follows: shooting data Canon 5D Mark IInbsp；; /EF 50mm f/ 1.4 USM/ aperture priority automatic exposure (F2.0, 1/500 seconds) /ISO 100/ white balance: Considering the distance between the camera and people in sunlight, the ef 50 mm f//kloc-with the nearest focusing distance of 0.45 meters was selected. The aperture is reduced to F2, which appropriately blurs the people in the background, but retains some atmosphere of the shooting scene. Flexible use of manual focusing (MF) to focus on the left eye part that is not at the autofocus point. Step 1: Set the shooting mode to automatic exposure with aperture priority (Av) and adjust the mode to automatic exposure with aperture priority (Av). Because the aperture value can be set first, it is easier to control the amount of blur. In the aperture priority automatic exposure mode, even if the brightness of the subject changes, the set aperture value will not change, but the appropriate exposure can be obtained by changing the shutter speed, so it is suitable for use when priority blur is needed. Step 2: Switch the focus mode switch to MF Select Manual Focus (MF) mode. This mode is not limited by the position of autofocus point, and can focus at any position in the viewfinder, which is suitable for portrait photography of various compositions to focus on people's eyes when moving. In addition, the fixed focus lens with bright maximum aperture makes the visibility in the viewfinder better, which is also a big point. Step 3: Hold the camera steady In order to get more accurate focus, fix your elbow on the table to keep the camera stable. Also pay attention to prevent the focus from blurring. In addition, this occasion uses the reflected light from the desktop and ceiling. While filling the face with light, the eyes also increase the eye light. You can think more when shooting and make effective use of the surrounding environment. Step 4: Determine the key observation after composition. The viewfinder determines the composition and accurately focuses on the center of the left eye. F2, which is close to the maximum aperture of the fixed-focus lens, can obtain an unimaginable small depth of field. So first of all, you should know where your eyes should focus before shooting. Step 5: Control the blur by changing the shooting angle of the face. When taking a close-up photo of the upper body with a large aperture fixed-focus lens, as long as the face orientation is slightly changed, the blurred position and the impression of the whole photo will be greatly changed. Legend has it that they are all shot at the same distance, but when shooting the front face, the whole face centered on the eyes or lips looks in focus, while when shooting the side face, half of the face is blurred. In portrait photography, it is suggested to consider the change of seemingly focused range (depth of field) and the change of blurred position caused by shooting angle. Column: Make the skin more beautiful by blurring the big aperture. Lenovo used EF 50mm f/ 1.4 USM to take a close-up of the face. Focus on your eyes. When the aperture is large, only the eyes focus, most of the skin is blurred, and the overall impression is very soft. As the aperture becomes smaller, the focus range becomes wider and the skin imaging becomes clearer. When you look at the picture, you will find that the face in the depth of the picture is basically clear at F8, but you can see that there is a tendency to blur, while the hair is blurred. Generally, I think the overall feeling of the picture should be very sharp in F8, but in close-range shooting such as portrait photography, even if the aperture value is large, it seems that the focus range is unexpectedly narrow. Therefore, it is easy to blur the focus by using a fixed-focus lens with a large aperture and blindly shooting at the maximum aperture. In portrait photography with short shooting distance, you should know that when choosing aperture value, you can get enough blur even if you narrow the aperture.
