I've been told over and over again that what makes me good at photography (besides the end product which is, of course, a lovely image) is my outgoing personality. Need someone to wrangle kiddos? Love to. Make a woman who is 8 months pregnant feel beautiful? Not a problem. Be "bossy" enough to wrangle 45 people into a group photo? I'd love to.
I choose to do photography/videography on the side because it's FUN (and I'm a tech geek who loves purchasing expensive tech equipment like new iMacs, DSLRs and crazy lenses for my camera. I think this allows me to charge less (which benefits my clients) and be choosier about who I want to work with (which benefits ME as I can work with super cool people... like I'm sure you are ;).
