What should I do if the background is not ideal when shooting?

Generally, various methods can be used to improve: 1. Adding mirror method: Choose some special additional mirrors to change the background around the main object. If you use a hollow filter when shooting, the image in the center of the picture will appear in natural color, while the image in the edge will appear in the color of the filter glass. This local discoloration method can be used to change the undesirable condition of the background. 2. Vignetting method: Put a UV lens on the lens, use a brush dipped in vitriol, and observe through the viewfinder. Applying vitriol to the lens will make the background behind the subject halo, which can improve the background. 3. Blur method: Use a very large aperture (such as F2 or F2.8) to reduce the depth of field as much as possible, so that the background of the subject in focus becomes blurred. In this way, using virtuality to contrast reality can also achieve good results. 4. Adding light method: If the shooting environment is not very bright, you can add some lighting sources (such as flash) in front of the subject. The exposure is based on the brightness of the illuminated subject in front. In this way, The background that is far away from the lighting source is relatively underexposed and dark, and the unsightly details on the background become difficult to detect. 5. Blocking method: During the post-enlargement process of the photo, a blocking plate is used to block the subject so that it remains correctly exposed, while the background behind the subject is overexposed, resulting in a dark tone and the original shortcomings of the background. Just disappeared. 6. Chasing photography method: If the subject is in motion, you can hold the camera in your hand and the camera will move at the same speed as the subject. When you have the right moment, you can press the shutter. Using this method to shoot, the cluttered background can be blurred by movement. 7. Slow exposure method: If the subject is stationary and the background is in motion (such as a busy street, a crowded market, etc.), you can use a tripod to fix the camera firmly, close the aperture, and extend the exposure relatively time.

In this way, during the slow exposure process, the scenery on the background will become blurred due to natural movement, and the cluttered background will no longer exist on the screen
