Onam AI trend: 10 ChatGPT and Gemini prompts to turn your selfies into festive Kerala photos & reels

Onam 2026 is getting an AI makeover, and you don’t need professional photography to join the trend. With tools such as ChatGPT and Gemini, users can turn an ordinary selfie into a traditional Onam portrait or create short cinematic videos featuring Kerala’s festive atmosphere, pookalams, kasavu outfits and even traditional celebrations.

The key is to give the AI a detailed prompt and, where possible, upload a clear photo as the identity reference. For videos, prompts work best when they clearly describe the opening frame, transformation, camera movement, lighting, background and ending shot.

Here are 10 copy-paste AI prompts, five for photos and five for videos, that can help you create your own Onam content.

5 AI prompts to create Onam photos

1. Cinematic Kerala Onam portrait

Prompt:

Create a highly realistic, cinematic Onam portrait using the uploaded photo as the exact identity reference. Preserve the person’s facial identity completely, including face shape, eyes, eyebrows, nose, lips, natural skin tone, age, hairstyle and all recognizable features. Do not beautify, reshape or replace the face.

Dress the person in an elegant traditional Kerala Kasavu saree with a cream-white body and refined gold border, styled naturally and realistically. Add simple traditional gold jewellery, small earrings and fresh jasmine flowers in the hair. Place the person in a beautiful traditional Kerala nalukettu-style courtyard decorated for Onam, with a detailed colourful pookalam, traditional brass nilavilakku lamps and subtle greenery in the background.

Use soft golden morning sunlight entering the courtyard, realistic skin texture, natural shadows and authentic fabric details. Keep the image sophisticated and photographic rather than overly decorative. The person should have a relaxed, natural expression and a candid editorial-portrait feel. Full or three-quarter body composition, realistic proportions, professional photography, shallow depth of field, cinematic but natural colour grading, high detail, no artificial-looking face, no text, no watermark.

2. Onam morning at home

Prompt:

Transform the uploaded photo into a photorealistic Onam morning scene while preserving the person’s exact identity. Do not alter the facial structure, skin tone, age, body proportions, eyes, nose, lips, eyebrows or other recognizable features.

Show the person standing just outside a traditional Kerala home on Thiruvonam morning, wearing an elegant cream-and-gold Kasavu saree with tasteful traditional jewellery and jasmine flowers. Create the feeling of a real family home preparing for Onam. Place a large, beautifully detailed pookalam at the person’s feet, with a traditional brass lamp glowing beside it.

Add subtle festive details in the background such as a Kerala-style wooden doorway, banana leaves, flowers and warm natural household surroundings. Use soft early-morning sunlight and realistic shadows. The person should look naturally happy, as though someone has captured an authentic Onam morning photograph rather than a studio portrait.

Photorealistic photography, realistic skin and hair texture, natural hands and fingers, authentic Kerala architecture, realistic saree folds, cinematic depth of field, warm but believable colours, no excessive decoration, no text, no watermark.

3. The grand Onam family portrait

Prompt:

Using the uploaded photo as the exact identity reference, create a realistic festive Onam family portrait. Preserve the person’s face and identity exactly and do not change their facial features, skin tone, age or body proportions.

Place the person in the centre of a large traditional Kerala family gathering during Onam. Dress the main subject in elegant cream-and-gold Kerala festive clothing. Surround them with family members of different ages wearing authentic traditional Kerala attire, creating the feeling of a real family photograph taken during the festival.

Set the scene in a traditional Kerala courtyard decorated with a large colourful pookalam, brass lamps and subtle floral decorations. Include natural interactions between the people rather than having everyone pose stiffly. Some people can be smiling at the camera while others interact naturally with one another.

Use warm afternoon Kerala sunlight, realistic shadows, natural skin textures and believable clothing. The image should look like a premium candid family photograph taken by a professional photographer, not an AI-generated fantasy image. Realistic hands, realistic faces, correct anatomy, natural expressions, detailed fabric and jewellery, no text or watermark.

4. Onam photoshoot in the rain

Prompt:

Create a cinematic, photorealistic Onam portrait using the uploaded photo as the exact identity reference. Preserve the person’s facial identity, skin tone, age, facial structure, hairstyle and recognizable features exactly. Do not create a different person.

Dress the person in an elegant traditional cream-and-gold Kerala Kasavu saree with minimal traditional jewellery and jasmine flowers. Place them on the veranda of a traditional Kerala house during a gentle monsoon rain. The courtyard should have a colourful pookalam that remains visible despite the rain, with warm brass lamps glowing under the covered veranda.

Show fine raindrops in the background, slightly wet stone flooring and realistic reflections from the soft light. Use a beautiful contrast between cool rainy surroundings and warm golden light from the house. The person should look naturally toward the camera with a subtle smile.

Create the look of a high-end Kerala fashion editorial photographed during the monsoon. Realistic rain, realistic wet surfaces, natural fabric texture, accurate anatomy, detailed skin texture, cinematic depth of field, soft bokeh, natural colour grading, no fantasy effects, no text, no watermark.

5. Vintage Kerala Onam photograph

Prompt:

Transform the uploaded photo into a photorealistic vintage-inspired Kerala Onam portrait while keeping the person’s exact facial identity unchanged. Preserve the face, skin tone, age, body proportions and recognizable features exactly.

Dress the person in traditional Kerala Onam attire — an elegant cream Kasavu saree with a gold border, traditional jewellery and jasmine flowers. Place them inside an old Kerala ancestral home with wooden pillars, traditional flooring and a subtle Onam decoration in the background. Add a beautifully arranged pookalam and a brass nilavilakku.

Give the photograph the visual character of a timeless family photograph from Kerala, with warm natural sunlight, gentle film grain and slightly muted tones. Keep the person’s face completely realistic and modern in detail while giving the overall photograph a nostalgic photographic quality.

Natural expression, authentic Kerala setting, realistic saree folds, realistic jewellery, correct hands and fingers, natural body proportions, subtle depth of field, no exaggerated beauty filters, no text, no watermark.

5 AI prompts to create Onam reels

1. Flower-throw transition — selfie to Onam look

Prompt:

Create a 5-second vertical 9:16 photorealistic Onam video using the uploaded photo as the exact identity reference. Start with the person exactly as they appear in the original photo, preserving their face, skin tone, age, hairstyle and natural body proportions.

The person smiles naturally, takes a handful of fresh yellow, orange and white flower petals and throws them directly toward the camera. The flowers move realistically toward the lens and briefly cover the entire frame. Use this moment as a seamless transition.

When the flowers clear, reveal the same person dressed in elegant traditional Kerala Onam attire, standing in a beautifully decorated Kerala courtyard with a colourful pookalam, brass lamps and lush greenery. The person gently adjusts their saree or mundu and looks toward the camera with a natural smile.

Keep the transformation smooth and realistic. Natural flower movement, realistic fabric and hair movement, accurate hands and fingers, natural facial expressions, cinematic camera movement and warm Kerala daylight. Do not change the person’s identity, face or body proportions. No face distortion, extra fingers, warped hands, duplicate people, text or watermark.

2. Making a pookalam — sitting on the floor

Prompt:

Create a 5-second vertical 9:16 photorealistic Onam video using the uploaded photo as the exact identity reference. Preserve the person’s exact facial identity, skin tone, age, hairstyle and natural body proportions.

Show the person sitting naturally on the floor of a traditional Kerala courtyard, wearing elegant cream-and-gold Kerala festive attire. In front of them is a partially completed pookalam. The person carefully picks up flower petals and places them around the design, gradually adding yellow, orange, white and pink flowers to the pookalam.

The camera begins with a medium shot and slowly moves closer to capture the person’s hands placing the flowers and the colourful pattern taking shape. Add a traditional Kerala house, brass nilavilakku and subtle greenery in the background.

Make the action natural and unhurried, like an authentic Onam morning at home. Realistic flower textures, natural hand movements, accurate fingers, realistic saree or clothing folds, soft morning sunlight and cinematic depth of field. No face distortion, no extra fingers, no unnatural body positions, no text or watermark.

3. Serving the Onam sadya

Prompt:

Create a 5-second vertical 9:16 photorealistic Onam video using the uploaded photo as the exact identity reference. Preserve the person’s exact face, skin tone, age, hairstyle and body proportions.

Show the person dressed in traditional Kerala Onam attire, serving a grand Onam sadya on a fresh banana leaf. The scene takes place at a traditional Kerala home during a festive family gathering. The person naturally serves different sadya dishes onto the banana leaf while smiling and interacting warmly with the people seated around the table.

Show realistic Kerala sadya dishes arranged beautifully on banana leaves, including rice, curries, avial, thoran, pickles and payasam, without making the food look artificial or excessive. Keep the focus on the person serving the meal.

Use warm natural daylight, realistic food textures, authentic Kerala surroundings and subtle background activity from family members enjoying the celebration. Natural hand movements and realistic serving actions are essential. Preserve exact identity throughout. No distorted hands, extra fingers, floating food, unrealistic faces, duplicate people, text or watermark.

4. Singing and dancing to an Onam song

Prompt:

Create a joyful 5-second vertical 9:16 photorealistic Onam celebration video using the uploaded photo as the exact identity reference. Preserve the person’s exact facial identity, skin tone, age, hairstyle and natural body proportions.

Place the person in a lively traditional Kerala Onam celebration. They are dressed in elegant Kerala festive attire and naturally singing along to a cheerful traditional Onam song while performing simple graceful Thiruvathira-style movements with a small group of people around a colourful pookalam.

The group should move together naturally in a traditional circular formation, with gentle coordinated hand movements and rhythmic steps. The main person should remain clearly recognisable throughout the video and appear to genuinely participate in the celebration rather than simply standing and posing.

Use bright festive daylight, traditional Kerala surroundings, realistic clothing movement, natural expressions and a joyful family-celebration atmosphere. The camera makes a gentle circular movement around the group before ending with the main person facing the camera.

Keep anatomy, hands, feet and facial features realistic. No exaggerated dance movements, no face morphing, no duplicate people, no distorted limbs, no text or watermark.

Optional audio instruction: Add a cheerful traditional Onam song or Thiruvathira-style festive instrumental in the background, synced naturally with the movement.

5. Onam swing — the nostalgic one

Prompt:

Create a cinematic 5-second vertical 9:16 photorealistic Onam video using the uploaded photo as the exact identity reference. Preserve the person’s exact facial identity, skin tone, age, hairstyle and natural body proportions.

Show the person wearing elegant traditional Kerala Onam attire, sitting gracefully on a traditional wooden swing hanging from a large tree in a beautiful Kerala courtyard. The swing is decorated subtly with fresh flowers.

The person gently swings forward and backward while smiling naturally. Their saree or traditional clothing moves softly with the motion, and jasmine flowers in their hair move naturally with the breeze. A colourful pookalam, traditional Kerala house and lush green surroundings can be seen in the background.

Begin with a slightly wider shot showing the beautiful Onam setting, then gently move closer as the swing comes forward. Capture warm golden sunlight filtering through the tree leaves, creating a nostalgic festive atmosphere.

Keep the swing movement physically realistic and smooth. Preserve the exact face and identity throughout. Realistic hair, fabric, flowers, hands and feet, natural body movement, authentic Kerala environment, cinematic depth of field, no face distortion, no warped limbs, no unnatural swing movement, no text or watermark.

Which prompts are best for Instagram?

For a quick transformation reel, the flower-petal transition is likely to be the easiest concept for audiences to recreate.

For photos, the rainy veranda and vintage Kerala concepts can make the result look less like the usual AI-generated Onam portrait and more like an actual photoshoot.

Bonus: Songs to pair with the reels

The audio can make a major difference to how the transformation feels. Depending on the mood, creators can look for currently trending Instagram audio around:

• “Onam Vannallo” — for a traditional, celebratory feel
• “Ponnonam” — for a nostalgic Onam mood
• Malare — Premam
• Pavizha Mazha — Athiran
• Jimikki Kammal — Velipadinte Pusthakam
• Vaathi Coming — Master (if the vibe is intentionally playful rather than traditional)
• Darshana — Hridayam
• A slowed/reverb Malayalam romantic audio that's currently trending on Instagram
• A cinematic instrumental with a strong beat drop — perfect for the moment the flowers cover the camera
