Dear 100 Hour Board,
Is it just me, or did people in the 40's-60's look more...attractive?
On top of monochromatic photography and videography being more forgiving than modern high-definition color photography and videography (as Anne mentions below), I think there's a certain romanticism and nostalgia that happens with black-and-white images. Additionally, if the only pictures you ever see are the famous and attractive people, you're going to have some selection bias in your sample.
As we learn from the prestigious source of all knowledge (Calvin's dad for all of you that don't know), the world used to be black and white. As it turns out, monochromatic people are more attractive. Thus, yes, people did used to be more attractive, but then all the world turned color, and beauty was lost.
