Just because it's an About Me page, doesn't mean you have to be really serious about who you are. Being aloof and nonchalant about things makes your About Me page interesting and fun to read. This also does not mean you shouldn't mention the work that you have done and how you got to your current situation throughout life. A casual explanation of who you are would help you connect with the reader while making you seem like a fun person they'd like to work with and hire in the near future. Two photographers that come to mind when having good and casual About Me pages are Danny Santos II (dannyst.com) a Singaporean photographer and the popular Brandon Stanton (humansofnewyork.com) of the very famous Facebook page called Humans of New York. Keeping it short and sweet and including a picture of yourself will make a very enjoyable About Me page for everybody.
