You can use your phone or your fancy, expensive camera to take your own photos, of course! And, I hope you take photos every chance you can.
But, photographers have the experience and the art of taking your photos from a different perspective and have the ability to capture moments of you and your loved ones that should illuminate feeling and produce quality photographs you would be proud to hang on your wall, use as a profile picture, or have sitting on your office desk for all to see!
