Diane Sawyer keeps her camera close ups on soft fuzzy focus. It reminds me of when Mae West got old and admitted to having her cameramen smear vaseline on the lense to soften her aura.
Walters too.......I saw her in a brief live interview and she definitely looked her age with puffy cheeks and sagging eyes.......
Makeup and camera work can take three decades off their faces.......
About 10 years ago I saw a local news reporter on the same plane as me when I was flying into Colorado.....she looked absolutely hideous without her makeup.......
