Things always look very different in photos than they do in person. Sometimes I think we get tunnel vision when doing hair or applying makeup or even getting dressed, and taking photos helps you get things back into perspective. I always like to take a step back when doing a client's hair and take another look at it with a fresh eye, and snapping a quick photo with my phone is another great way of making sure things are perfect. Having a photo booth would also be a great way to make sure you or your client is looking good. Wouldn't that be so much fun?
