I am a firm believer that every single girl (or any girl, for that matter) needs to be able to take a good-quality self portrait. Taking photos of our many adventures is all well and good, but documenting life from behind the camera eliminates the possibility of being in front of it; which kind of sucks. Enter the self-portrait.
One of my favorite things about looking through these photos are the little things, those little details that mark the passage of time: the hair color, the skin changes (pale like Casper!), the hair, the itty bitty differences in expression, etc. Those teeny differences help shape the larger ones, especially those you've lived with so long you barely notice.
Because you should be in your photos. And you don't need to depend on someone else to take a photo that you love.
