I have been for the past 8 years a School Photographer working with kids ranging generally from K-12. On occasion we'd have younger kids in who were just so happy to be in front of the camera and couldn't help but just give me those little smiles while I got their photos.
Being behind the camera helps me to capture those smiles before the kids grow up, and the families want to be able to look back on the memories as their kids grow up. I do have an eye for detail, so I am naturally checking the kids as they come up to the camera to make sure they are as set as they can be for their picture,
