UGC = "not selling" feeling
UGC's power is producing a sharing feel, not a selling one. Studio light, perfect composition, blue corporate background — they all trigger the ad alarm. Natural light, a slightly messy desk, a real hand build trust instead.
Hand details
A professional model's hand triggers the ad alarm. A regular hand, slightly worn nails, a wedding ring or everyday bracelet says "this is a real person." If that's what you want, write it in the prompt: "everyday hand, no manicure".
Environment cues
A coffee cup in frame, an open notebook, a slightly messy bookshelf — these are real-life signals. A sterile counter says "studio"; the same counter with a pair of glasses in the corner says "home."
Camera angle
Drone-style top-down feels professional. Eye level feels intimate. For UGC, eye level or slight POV from above is ideal.
