Apply a .cube LUT to a Photo
Applies an Adobe/Resolve .cube LUT (1D, 3D or a 1D shaper plus 3D table, DOMAIN_MIN/MAX and LUT_*_INPUT_RANGE) to a PNG, JPEG or WebP image with tetrahedral or trilinear interpolation, mixed at the strength you choose. Reports the LUT type, size and how much the image changed.
| Field | Type | Default | Description |
|---|---|---|---|
image (required) | file | — | Photo (PNG, JPEG or WebP, up to 2 megapixels) |
lut | file | — | .cube LUT file |
cubeText | textarea | — | Or paste the .cube text |
interpolation | select (tetrahedral, trilinear) | "tetrahedral" | Interpolation |
strength | number | 100 | Strength |
space | select (srgb, linear) | "srgb" | The LUT expects |
format | select (png, jpeg, webp) | "png" | Output format |
quality | integer | 90 | JPEG/WebP quality |
Every result contains
inputs (normalised, defaults applied), summary, result (validated against the published schema), units, assumptions, sources, warnings, computedAt and links.
