Half Shade campaign
Outdoor brand campaign poster for an invented Australian sunscreen brand called HALF SHADE. Photograph: a 72-year-old Greek Australian man, short and barrel-chested, deeply tanned and wrinkled skin, white chest hair, a battered straw hat, a white singlet, a thick stripe of white zinc cream across his nose, stands proudly in his backyard vegetable garden in suburban Melbourne holding up a huge bunch of homegrown tomatoes on the vine, tall tomato plants on stakes, a rotary washing line and a corrugated tin fence behind him, harsh midday sun, shot from slightly low. Typography: the HALF SHADE wordmark in a heavy rounded sans serif in white at the bottom left; under it, small: "Made for people who stay out too long."; at the bottom right a white sunscreen tube with an orange cap printed with the same wordmark. Hard sun, crisp shadows, real skin. No other text.

KOLO, shot 3
Vertical candid selfie photo taken at arm's length, the photo itself filling the frame, misty dawn light: a 44-year-old Black dad with a big full beard flecked with grey, a knit beanie and a red flannel shirt sits in the open door of a tent beside a misty lake in north Georgia, kids' sleeping bags just visible behind him, holding the terracotta espresso maker from the reference image. No readable text, no logos. Real UGC look: this image is the photo itself, full frame, as a phone camera would capture it; never show a phone, a screen, a bezel or a status bar. Natural light, slight wide-angle distortion, unpolished.

KOLO, shot 4

No readable text, no logos. Real UGC look: this image is the photo itself, full frame, as a phone camera would capture it; never show a phone, a screen, a bezel or a status bar.
