I feel like I prefer candids to professional photos of my ancestors but I still find myself only saving formal photos of me and my family. Trying to branch out.
Many times it's not the photo, but the story behind the photo. My favorite photo of my father is this one of him at about 2 years old with an aviator hat on. He became a small aircraft pilot as an adult. https://www.familysearch.org/tree/person/memories/LNDP-VRH
For additional examples of photos attached to stories see his person page at: https://www.familysearch.org/tree/person/details/LNDP-VRH
Focusing on the photo, This is the cutest photo ever. Two young children in a goat cart.
