Gen Z students hanging out in a small apartment, simple food moment, one person holding a sandwich with bologna sausage, casual messy environment, laughter and authenticity, realistic lifestyle photography, focus on social connection
Photoreal cinematic fashion still, expensive outdoor editorial in snowy mountains during a strong blizzard. A young woman with the facial features from the second reference only (same bone structure, eyes shape, cheekbones, lips, brows), no sunglasses, no hood, no extra accessories. She wears a heavy natural fur coat like the first reference, wind whipping loose hair strands across her face, snowflakes stuck on hair and fur, visible cold breath, natural skin texture with pores and subtle freckles, slightly flushed cheeks from cold. Pose and camera angle match the first reference: medium close shot, straight-on perspective at eye level, filled frame, intense calm gaze slightly past the lens, not smiling. Environment: desaturated snowy landscape and rocky mountain forms blurred in the background, heavy snowfall and wind-driven snow streaks, shallow depth of field. Shot on Hasselblad H6D-100c, 120mm f/4 Macro lens, ISO 100, f/4, 1/200s, ultra-sharp center focus on the eyes, shallow DOF with softly blurred edges. Lighting: on-location large diffused softbox front-top at 45° for smooth even key, no harsh shadows; subtle rim light from behind to outline head and emphasize fur texture; silver/white reflector low front to lift shadows under nose and chin; clean controlled specular highlights on skin and hair, crisp micro-contrast only in the focal plane. Color grading: warm editorial grade, clean skin tones with preserved pores, minimal contrast, slight magenta shift in fur tones, subtle golden reflections in highlights, gentle cinematic softness plus fine high-quality micro-grain.
Minimalist flat lay pregnancy announcement, soft white fabric background, a small white frosted cake with delicate piped edges decorated with blush pink flowers, elegant white frosting and the word "Baby" written on top, placed beside a knitted cream baby romper with bear ears and a pink bow accent, a printed ultrasound photo arranged next to the cake, a bouquet of baby’s breath mixed with blush roses scattered gently, warm natural light, soft pastel tones, cozy and feminine atmosphere, modern photography style, no text
A charming Flower shop exterior in the style of Whymsical Storybook. The storefront features crooked wood details and a hand-painted sign that reads "Flower Shop". The window display is filled with flower bouquets, potted plants, and delicate floral arrangements. Outside the shop, there are baskets of flowers, watering cans, wooden crates, and a friendly shop cat. Subtle trailing vines around the doorway and small floral accents near the windows. Color palette in bright pinks, bright greens, creams, and neutrals. Minimal background to keep the focus on the shopfront. Perfect for floral clip art.
