Now, the important piece: It really does work. I tried it during a family portrait job I was hired to shoot and while it wasn't really necessary for the older kids, the toddlers were mesmerized by it and it held their attention. And because the phone sites so close to the lens, their gaze really does look straight on (in most cases, but I'll get to that in a minute). It beats the look you have mom or dad standing over your shoulder. I had similar results with a quick test I did on my dog, but she lost interest even more quickly than the kids.
