Getting fed up with all sorts of (mobile/web) Apps promising to enhance your pictures or do some creative/fun AI processing for you, i eventually ended up using Nano Banana. What can i say .. i am overwhelmed how good Image processing has become.
For the examples below i’ve used my blog picture as a reference ( which isnt even ideal but shows how good processing is ) and a few prompts i rephrased from found examples on the web or even suggested by chatgpt.
Prompt: Hyper-realistic pulp fiction–style close-up using my selfie as exact face reference. Strong shadows, bold color lighting, confident smirk or focused gaze. Background painted in dramatic abstract shapes. High contrast, retro cinematic color grading, modern realism fused with classic pulp illustration energy, 8K.

Prompt: A hyper-detailed, high-contrast black-and-white portrait of a confident young man using the exact same hairstyle as in the uploaded reference photo, with no changes, no added volume, and no reinterpretation. Facial features and hairline must match the original image precisely. Calm, determined expression. One eye partially obscured by a bold red rectangular overlay and geometric frame. Minimalist textured grey background. Vertical text on the left repeating “AWESOME” in large, semi-transparent black letters. Modern red graphic accents including a vertical line, a stylized red “MRi,” and a subtle Nike logo. Bottom right text reads “LESS HUSTLE. MORE IMPACT” in bold red capitals, with “impact” in elegant cursive beneath, signed “Graphics.” Bottom left features the red hashtag “#MRi-LE.” Soft yet dramatic lighting, strong texture detail, red accents popping against grayscale. Streetwear-inspired graphic design, photorealistic, shallow depth of field, DSLR quality, Hasselblad X2D 100C, 4:5 aspect ratio, 8K, ultra-realistic.

Prompt: Generate a black and white closeup portrait showing just the right side of the man's face, emerging from water. His skin and hair should be wet, with visible water droplets and small bubbles. Use dramatic lighting to highlight the illuminated side while leaving the other side in deep shadow. Emphasize the texture of his skin, beard stubble, and sharp eye detail. The mood should feel intense and cinematic, with a dark, minimal background.

Prompt: Create a hyper realistic 8K studio photograph shot on a 50mm prime lens with a wide aperture, showing a miniature caricature keychain held in the foreground by a human hand in a close-up, slightly low-angle composition with shallow depth of field and soft bokeh suggesting an indoor retail setting. The keychain has a silver split ring, a dark blue strap with a white geometric pattern and embossed "Happy Holidays" text, connected by a short silver chain to a detailed caricature charm with an oversized head and small body riding a bright yellow vintage Vespa. The character's face, expression, and proportions are taken 100% from the uploaded reference image with no gender assumption, wearing a yellow knit beanie, yellow-and-black striped sweater, blue denim shorts, white socks, and green high-top sneakers. The Vespa features a brown seat, silver handlebars and mirrors, a glowing headlight and realistic tires with glossy textures, while cinematic studio lighting highlights reflections and details, and the hand shows natural skin texture and realistic shadows for a photorealistic finish.

Prompt: Verwandle das Motiv in eine klassische Baseball-Wackelfigur, die eindeutig als hergestelltes Sammlerstück erkennbar ist und nicht als Person. Der Kopf ist stark übergroß, sodass er kopflastig und verspielt wirkt, und über einen kurzen, steifen Hals mit dem Körper verbunden, der eher an eine Feder als an Anatomie erinnert. Bewahre die Gesichtserkennung des Motivs, vereinfache jedoch die Merkmale und stelle das Gesicht als glatt matt lackierte Vinyloberfläche ohne Poren oder lebensechte Textur dar. Die Gesichtsflächen sollen vereinfacht und grafisch wirken, mit minimalen Oberflächendetails. Haare und Bart sollen vollständig skulptural erscheinen, mit geschnitzten Rillen und klaren Formen statt einzelner Strähnen. Kleide die Figur in eine Baseballuniform, inspiriert von den Farben der ursprünglichen Kleidung des Motivs oder der lokalen Teamästhetik, umgesetzt als stimmiges Trikot, Kappe und Accessoires. Der Körper soll klein, starr und spielzeughaft sein. Platziere die Figur vor einem gedruckten oder sanft illustrierten Baseballstadion-Hintergrund, sodass die Szene wie eine sammelbare Präsentation wirkt, nostalgisch und unverkennbar eine Wackelfigur. Füge keinen Namen auf der Figur hinzu.

Prompt: Use the uploaded image as an img-to-img reference, preserving full facial likeness and identity, and create artwork that appears drawn on lined notebook paper with ballpoint pen, ink, and neon markers, showing realistic ink absorption, layered pressure, smudges, stains, wrinkles, and worn edges. The style blends chaotic doodle art, comic annotations, and rough sketches with thick-thin line variation, loose strokes, messy marks, dynamic hatching, and energetic spontaneous, slightly chaotic mood, rendered in high detail at 4K with bold outer glow lighting and vibrant contrast. Use a portrait composition with a thick border around the head, surrounding the subject with arrows, stars, underlines, scribbles, speech bubbles, overlapping notes, checkboxes, playful icons (lightning bolts, lightbulbs, music notes, a small self-caricature), and handwritten comic sound effects like “ZAP!” and “WHOOSH!”. Apply one style variation: Pop Bold (cyan and magenta), Neon Highlight (neon pink and yellow highlighter look), Electric Graffiti (electric blue and neon red graffiti outlines), or Dense Sketch (blue linework with red accents, dense and alive).
