During photography, the camera will try to adjust the exposure automatically to make the image look balanced and uniform. However, when taking color photos with white background, if people wear white clothes, the exposure setting of the camera may be problematic, because it will try to distinguish the background from people. Therefore, this may lead to blurred or overexposed facial and body details of people, thus affecting the quality and accuracy of photos.
So in order to avoid this situation, it is best to choose other colors, such as dark or bright colors.
