Father & Son in white blank T-shirts Outdoor

A father and son having a joyful day out wearing matching white blank T-shirts. Doing weekend activities at the beach, park or outdoor area. Father in his 20s or early 30s and toddler son. Both should be slim and long (fit). Chest area to be visible and unobstructed (as we will superimpose a graphic) and should be wrinkle free (can be edited in Photoshop for wrinkle removal)

Framing for the upper torso (mid-thigh and up) Shallow DOF preferred but both models must be in focus. Flash fill is fine but image should be dominated by natural light. We will purchase 5 to 10 images from the same shoot (assuming we like the results). Images to be in JPG 4K pixels (on short side) and up.
