When it comes to portraits of loved ones, all the client sees is the smile or the eyes or the emotional connection between the subjects if there is more than one person in the photo. Non photographers don't care about catch lights or fill flash or blown highlights. They may like a technically correct or superior quality photo more than the same subject/pose that has these issues but they won't know why. There is a photographer in my small city who is supremely popular for family portraits - a "natural light" photographer. We have a lot of mutual friends on Facebook and I frequently see her work posted there by thrilled clients. I always mentally critique the photo but I see dozens of comments on how great it is. They don't care about lack of fill flash or trees growing out of heads, they see only little Mary with her baby brother at sunset on the beach - as long as there is some background blur, everyone is happy. Ignorance really is bliss!
