Prompt to image, in context

Create a photorealistic candid photograph of an elderly sailor standing on a small fishing boat. He has weathered skin with visible wrinkles, pores, and sun texture, and a few faded traditional sailor tattoos on his arms. He is calmly adjusting a net while his dog sits nearby on the deck. Shot like a 35mm film photograph, medium close-up at eye level, using a 50mm lens. Soft coastal daylight, shallow depth of field, subtle film grain, natural color balance. The image should feel honest and unposed, with real skin texture, worn materials, and everyday detail. No glamorization, no heavy retouching.

Create a simple biology diagram titled "Cellular Respiration at a Glance" for high school students. Show how glucose turns into energy inside a cell. Include glycolysis, the Krebs cycle, and the electron transport chain. Use arrows to connect the steps, and label the main molecules: glucose, pyruvate, ATP, NADH, FADH2, CO2, O2, and H2O. Make it look like a clean classroom handout or slide, with a white background, simple icons, clear labels, and easy-to-read text. Avoid tiny text, extra decoration, or anything that makes the diagram hard to understand.

Create a realistic mobile app UI mockup for a local farmers market. Show today’s market with a simple header, a short list of vendors with small photos and categories, a small “Today’s specials” section, and basic information for location and hours. Design it to be practical, and easy to use. White background, subtle natural accent colors, clear typography, and minimal decoration. It should look like a real, well-designed, beautiful app for a small local market. Place the UI mockup in an iPhone frame.

Give me a cool in culture ad / fashion shot for a brand called Thread. It's a hip young street brand. The ad shows a group of friends hanging out together with the tagline "Yours to Create." Make it feel like a polished campaign image for a youth streetwear audience: stylish, contemporary, energetic, and tasteful. Use clean composition, strong color direction, natural poses, and premium fashion photography cues. Render the tagline exactly once, clearly and legibly, integrated into the ad layout. No extra text, no watermarks, no unrelated logos.

Turn this drawing into a photorealistic image. Preserve the exact layout, proportions, and perspective. Choose realistic materials and lighting consistent with the sketch intent. Do not add new elements or text.

Preserve the same woman, same face, same pose, same headphones product design, same overall layout structure, same camera angle, and the same premium commercial advertising style. Redesign the image into a bold limited-edition holiday launch campaign while keeping the poster highly polished and product-focused. Change the color accents from subtle blue to deep red and warm gold. Update the typography styling to feel slightly more festive and luxurious, while preserving clean commercial readability and strong layout hierarchy. Replace the text exactly as follows, keeping all text perfectly spelled, aligned, and clearly legible: “Wireless Headphones for Focused Listening” “Luxury Wireless Headphones for Everyday Escape” “Immersive sound. All-day comfort. Up to 40 hours battery life.” “Signature sound. Premium comfort. Limited holiday edition.” “Available in Onyx Black, Champagne Gold, and Winter Ivory” “Includes carrying case, USB-C cable, and 3.5 mm audio cable” “Includes premium hard case, USB-C cable, audio cable, and travel pouch” Add one extra small elegant label near the product close-up: Keep the product rendering realistic and detailed, preserve the woman's identity and styling, and ensure all updated text is sharp, professional, and perfectly readable. Premium commercial product poster, photorealistic, polished, typography-rich, visually refined.

Create a realistic billboard mockup of the shampoo on a highway scene during sunset. Billboard text (EXACT, verbatim, no extra characters): "Fresh and clean" Typography: bold sans-serif, high contrast, centered, clean kerning. Ensure text appears once and is perfectly legible. No watermarks, no logos.
