Overview

Relight examples (from top left to bottom right): Original image, Night scene, Snowy landscape, and Hell scene.

Image Relight allows you to change the entire lighting of a scene and, optionally, the background using:

  1. A prompt
  2. A reference image
  3. A light map

This tool can simulate different lighting scenarios, enhance details, and create artistic effects. Our API lets you transform your images with custom prompts and fine-tuned parameters for impressive results.

Image Relight uses Magnific.ai technology, now available as a comprehensive API service.

Looks amazing take me to the code already!

Key Parameters

image
string
required

Base64 encoded image to relight

prompt
string

Guide the relighting process. Use descriptive prompts to influence the light transfer (e.g., “A sunlit forest clearing at golden hour”).

Tip: Use weights to emphasize parts of your prompt. Add a number in parentheses (1 to 1.4) after a phrase, like “(dark scene:1.3)“.

Note: Incompatible with ‘transfer_light_from_reference_image’ and ‘transfer_light_from_lightmap’.

transfer_light_from_reference_image
string

Base64 encoded reference image for light transfer.

Note: Incompatible with ‘prompt’ and ‘transfer_light_from_lightmap’.

You must select either ‘prompt’, ‘transfer_light_from_reference_image’, or ‘transfer_light_from_lightmap’. Only one of these parameters should be provided.

transfer_light_from_lightmap
string

Base64 encoded lightmap for light transfer.

Note: Incompatible with ‘prompt’ and ‘transfer_light_from_reference_image’.

light_transfer_strength
integer
default: "100"

Specify the level of light transfer (0 to 100). Lower values keep the image closer to the original, while higher values apply more light transfer.

interpolate_from_original
boolean
default: "false"

When enabled, this feature will make your final image interpolate from the original using the “Light transfer strength” slider.

change_background
boolean
default: "true"

When enabled, it will change the background based on your prompt and/or reference image.

style
string
default: "standard"

Style options for the relighting process:

  • standard: General-purpose relighting
  • darker_but_realistic: Darker tones with realistic lighting
  • clean: Clean and simple lighting
  • smooth: Smooth lighting transitions
  • brighter: Brighter lighting
  • contrasted_n_hdr: High contrast and HDR effect
  • just_composition: Focus on composition without changing lighting
advanced_settings
object

Advanced settings for fine-tuning the relighting process:

  • whites: Adjust the level of white color (0 to 100)
  • blacks: Adjust the level of black color (0 to 100)
  • brightness: Adjust the brightness level (0 to 100)
  • contrast: Adjust the contrast level (0 to 100)
  • saturation: Adjust the saturation level (0 to 100)
  • engine: Choose the relighting engine (automatic, balanced, cool, real, illusio, fairy, colorful_anime, hard_transform, softy)
  • transfer_light_a: Adjust the intensity of light transfer (automatic, low, medium, normal, high, high_on_faces)
  • transfer_light_b: Modify light transfer intensity (automatic, composition, straight, smooth_in, smooth_out, smooth_both, reverse_both, soft_in, soft_out, soft_mid, strong_mid, style_shift, strong_shift)
  • fixed_generation: When enabled, using the same settings will consistently produce the same image.

Selecting Light Transfer Method

Choose one of these three ways to transfer light in Image Relight:

  1. Prompt Describe the desired lighting using text. Specify characteristics like color, time of day, type and shape of light. Example: “A sunlit forest clearing at golden hour” or “Under the water”

  2. Reference Image Provide an image to transfer lighting from. Image Relight will replicate the light, colors, and shadows from this reference.

  3. Lightmap Create custom lighting with your own lightmap image:

    • Black represents absence of light
    • Lighter colors (including white) indicate presence, color, and shape of light sources
