It is not necessarily true that older people appear more attractive in black and white photos. While black and white photography can be an artistic choice that can add a sense of timelessness or drama to an image, it does not inherently make a person look more attractive. The attractiveness of a person in a photograph depends on a variety of factors, including their facial structure, skin quality, and overall appearance.
That being said, black and white photography can be a useful tool for emphasizing certain features or details in a photograph. For example, strong contrasts between light and dark can draw attention to specific areas of the image, which can be particularly effective in portraits. Additionally, the lack of color in a black and white photograph can help to minimize distractions and allow the viewer to focus more on the subject of the photo.
Overall, whether or not older people appear more attractive in black and white photos is subjective and depends on a variety of factors. While black and white photography can be a powerful medium for artistic expression, it does not inherently make a person look more attractive, regardless of their age.
