Knowledge Point 01: Turn off Flash and Indoor Lighting When Taking Photos of TV Screens to Avoid Reflection Interference
When capturing images of TV screens, it is crucial to turn off flash and indoor lighting, as these light sources can produce reflected light on the TV screen that interferes with the transmitted light of the TV image, thereby affecting photo clarity.
Detailed Explanation:
When using flash or indoor lighting to take photos of TV screens, the light from these sources reflects on the TV screen, creating an additional layer of light. This reflected light overlaps with the transmitted light of the TV image, causing the TV image in the photo to appear blurred or have double images.
To obtain clear photos, it is advisable to avoid these additional light sources during shooting and allow the camera to directly capture the transmitted light of the TV image.
Knowledge Point 02: Mirror Distortion Increases Proportionally with the Distance Between the Person and the Mirror
Mirrors become more distorted as the distance between the person and the mirror increases, due to uneven silvering on the mirror surface or uneven glass thickness.
Detailed Explanation:
The imaging principle of mirrors is to form images by reflecting light from the silvering surface. If the silvering surface is uneven or the glass thickness is inconsistent, the reflected light will deviate from its normal path, leading to image distortion or deformation.
As the person moves farther away from the mirror, due to the amplification effect of light, the minute unevenness in the silvering surface or the inconsistency in glass thickness will be amplified, causing the image in the mirror to become more distorted.
