Overview
A lookup curve applied per channel — remap input values to output values point by point.
How to
How-to
- Pull the
mastercurve or a per-channel curve; the x axis is input level, y is output. source/targetremap the curve's domain when the image is not 0–1.
Inputs
| Input | What it takes |
|---|---|
| in | the image this node works on |
| mask | limits the effect to this matte — the engine's universal mask slot, applied for every node that declares it |
Outputs
| Output | Type |
|---|---|
| out | Image |
Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| master | Lut | 2 points | The curve on every channel. |
| red | Lut | 2 points | The channel's own curve, after master. |
| green | Lut | 2 points | The channel's own curve, after master. |
| blue | Lut | 2 points | The channel's own curve, after master. |
| alpha | Lut | 2 points | The channel's own curve, after master. |
| source | Color | [0.0, 0.0, 0.0, 1.0] | Plate match, step 1: a colour sampled from the plate. |
| target | Color | [0.0, 0.0, 0.0, 1.0] | Plate match, step 2: the colour it should become. Add the mapping points to the curves. |
| black_clamp | Bool | false | Clip the result at 0 — no negative values leave the node. |
| white_clamp | Bool | false | Clip the result at 1 — no values above white leave the node. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. | |
| hide_input | Bool | false | Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap). |
