I've come across this fantastic blog post recently, explaining why you might not think you look like the person in your professional portraits. The blog was written by Roxanne Elise Photography and I personally find it fascinating. Obviously these are things that I am aware of as a portrait photographer, but I've never actually done the experiment on myself and been able to compare the results. Seeing just how different Roxanne looks in all of her portraits is surprising!
Definitely worth remembering when you finally see yourself in your new portraits!
