I am 19 years old and I love being a photographer and taking pictures. I have recently decided to start a very small side "business". Basically just to make a little cash here and there. I have set up a Facebook page and so far have only done one photo shoot of my baby cousin. I am wondering if I need to obtain a license before I start photographing other people outside of my family. I do simple on site photography. I don't photograph in home nor do I have a studio. I just do not want to get into any sort of legal trouble. Thanks in advance!
