How it works

  1. Upload your photo

    Upload a clear photo showing the area you want to edit. Good lighting and sharp focus help the AI deliver better photo lighting results. JPG, PNG, WebP up to 7MB.

    Expect: Simple relighting (add soft light): 20-30 seconds. Complex dramatic changes (flat to cinematic): may need 2-3 refinements to perfect shadows and highlights.
  2. Describe what you want

    Type your instruction: 'add dramatic side lighting from the left with strong shadows' or 'relight with soft diffused window light from upper right.' Specify direction (left/right/above/below) and quality (soft/dramatic/harsh/diffused). No marking needed—the AI understands lighting.

    Tip: Include light quality and direction: 'soft window light from left' creates very different results than 'harsh spotlight from left.'

    Copy one of these to get started:

    Add dramatic portrait lighting add dramatic side lighting from the left with strong shadows and highlighted edges, cinematic portrait look
    Soft natural window light relight with soft diffused window light from upper right, gentle shadows and natural flattering glow
    Golden hour warm glow relight with warm golden hour sunlight from the left, soft shadows and warm orange-gold highlights
    Cinematic backlighting add cinematic backlight from behind the subject with rim light highlighting edges and atmosphere
    4 more prompts
    Studio spotlight relight with focused studio spotlight from above, dark dramatic shadows and bright central highlight
    Bright overhead sunshine add bright overhead sunlight with crisp shadows falling downward, clear sunny day look
    Moody low-key lighting relight with moody low-key lighting, mostly shadows with subtle highlight on one side of the face
    Even beauty lighting relight with even soft beauty lighting from the front, minimal shadows and flattering smooth illumination
  3. Generate and review

    AI analyzes your subject and adds new lighting with realistic shadows, highlights, and ambient fill. Zoom to verify shadows fall naturally and highlights are placed correctly. Check that the new lighting matches what you described.

  4. Refine the lighting if needed

    If shadows are too harsh or highlights too bright, regenerate with adjusted instructions: 'soften the shadows a bit' or 'make the highlight more subtle.' This is optional—many relighting edits work perfectly on first try.

    Tip: Relighting is subjective. Try variations: 'more dramatic' or 'softer lighting' to find your preferred look.
  5. Download your relit photo

    Download in full resolution with no watermark. Your photo now has professional lighting that would normally require expensive studio equipment or hours of manual editing.

Quick answers

Do I need to mark anything before describing the lighting?

No! Just describe the lighting you want: 'add dramatic side lighting from the left' or 'relight with soft window light.' The AI identifies your subject and applies lighting automatically. Relighting works on description alone—no marking needed.

How do I relight a photo for free?

Upload your image to EditThisPic and describe the lighting you want—direction (left/right/above), quality (soft/dramatic/harsh), and style (golden hour/studio/cinematic). The AI analyzes your subject and adds realistic lighting with proper shadows and highlights. Free to use, no account needed.

Can this work on photos that already have lighting?

Yes, the AI can modify or replace existing lighting. For best results, start with evenly-lit or flat-lighting photos. Photos with strong existing directional light may need 'replace existing lighting with...' to indicate complete transformation rather than addition.

What's the difference between relighting and exposure adjustment?

Exposure makes images brighter or darker uniformly. Relighting adds directional light sources with realistic shadows, highlights, and light fall-off patterns—like moving your subject to different lighting conditions. Relighting changes where light comes from and how it shapes your subject.

Will relighting work on portraits, products, and other subjects?

Yes, relighting works on portraits, products, food, architecture, and most subjects. Results are best on clear subjects against simple backgrounds. Complex scenes with many elements may need refinement. Portraits tend to work excellently.

Can I simulate specific lighting setups like Rembrandt or butterfly lighting?

Yes! Describe classic setups: 'Rembrandt lighting from 45 degrees left' or 'butterfly lighting from directly above.' The AI understands photography lighting terminology and can recreate standard studio setups.
