Why Emily5?

Several years ago, while in college and dating my husband, Troy, I took a picture of the city skyline of St. Pertersburg, FL on vacation. Troy loved this picture and wanted a copy of it for his office. So, for Christmas one year I enlarged a copy of this picture, and framed it for him. When I went to sign the picture as an Emily original: "Emily S" I got nervous that I would mess it up and I wrote what looked like "Emily 5" instead. My husband thought it was funny and said if I ever become a photographer, that Emily5 had to be the name of the business.
I thought it was creative, and have signed all my pictures as such since.
