Depth Adjust
The Levels tool for a depth image — or any grayscale driver. Invert swaps near and far; In Black/White clip and stretch the range like a Levels dialog; Gamma bends the midtones, Contrast steepens them; Out Black/White compress into a target band; Posterize cuts the ramp into discrete depth slices. Band mode is the scalpel: a mask that peaks at Band Center and falls off over Band Width — one exact slice of distance, ready to gate any filter. Sits perfectly between the 3D Scene's Depth pass and a Depth of Field, Fog or Film Grain mask.
Inputs
| Port | Type | Default |
|---|---|---|
| EnableOff passes nothing: the texture is cleared. | bool | true |
| ImageThe depth image — or any grayscale — to reshape. | image | — |
| WidthWidth of the output picture in Grafit units (default 2, the full height of the view). Cable the source's Width to keep its size. | float | 2 |
| HeightHeight of the output picture in Grafit units (default 2). | float | 2 |
| ModeLevels reshapes the whole ramp like a Levels dialog; Band carves ONE slice of it into a mask. | int | 0 |
| InvertSwaps near and far — the negative depth. | bool | false |
| In BlackEverything at or below this reads black; the range above stretches to fill. The clip-and-stretch half of Levels. | float | 0 |
| In WhiteEverything at or above this reads white. | float | 1 |
| GammaBends the midtones: above 1 lifts them, below 1 sinks them. The curve half of Levels. | float | 1 |
| ContrastSteepens the ramp around the middle; at +1 it approaches a hard threshold, negative flattens. | float | 0 |
| Out BlackWhat black becomes on the way out — compress into a target band. | float | 0 |
| Out WhiteWhat white becomes on the way out. | float | 1 |
| PosterizeCuts the ramp into this many discrete steps — depth SLICES, contour bands. 0 or 1 is off. | int | 0 |
| Band CenterWhere on the depth ramp the band mask peaks — the exact distance you want to isolate. | float | 0.5 |
| Band WidthHow much of the ramp the band covers before falling to black. | float | 0.3 |
| Band FeatherHow soft the band's edges are, as a fraction of its half-width. | float | 0.1 |

How It Works
Depth Adjust is a Levels dialog for distance — or for any grayscale driver. Invert swaps near and far. In Black and In White clip and stretch the incoming range exactly like a Levels dialog. Gamma bends the midtones and Contrast steepens them. Out Black and Out White compress the result into a target band. Posterize cuts the ramp into discrete depth slices.
Band mode is the scalpel: instead of a ramp it produces a mask that peaks at Band Center and falls off over Band Width, feathered by Band Feather — one exact slice of distance, ready to gate any filter downstream.
It is designed to sit between the 3D Scene's Depth pass and a Depth of Field, a Fog or a Film Grain mask, where the raw pass rarely lands in the range the consumer wants.
Use Cases
- Get depth into range — A scene whose depth all sits between 0.4 and 0.6 becomes a full ramp with In Black and In White.
- Isolate a slice — Band mode masks exactly the objects at one distance, for a colour grade or an effect that only they receive.
- Stylised depth — Posterize turns a smooth ramp into flat planes, the cel-shaded look.
- Gate grain to the background — Band the far distances and feed the mask to Film Grain.
- Tame an estimated map — Depth Estimation's relative output becomes predictable after a Levels pass.
Tips
- Set In Black/In White first, then Gamma. Doing it the other way round means re-tuning the gamma every time you clip.
- Band Feather stops a mask from having hard edges — a little always looks better than none.
- Any grayscale works here, not just depth: a luminance pass, an ID pass or a hand-painted mask all respond to the same controls.
- Chain two Depth Adjusts when you want a ramp and a band from the same source.
- Preview the result by cabling it into a Canvas — reading a depth ramp by eye is much easier than by numbers.
