I was reminded of this by the exact opposite. While checking equipment for an event I asked my daughter to take a shot. She asked me to raise my head towards the light and being shorter than me the first image had an air of “I look down on you” that I wasn’t happy with. Getting onto my knees changed her view point in relation to my face and the second shot was much better.
Getting below eye level can help at times, for example power dressing fashion or corporate shots, but be careful not to have the subject lower their head to look at the camera. Doing so will create or enhance a double chin!
