Exposure
Exposure applies a multiplicative brightness gain to the whole image — the same math as adjusting shutter speed after the fact, expressed in stops (EV). It runs early in the pipeline, before highlight/shadow recovery and tone mapping, so it affects the source data those later adjustments work from.
Parameters
| Parameter | Type | Range | Default | What it does |
|---|---|---|---|---|
| EV | number | -5 to 5 | 0 | Exposure gain in stops. Positive brightens, negative darkens. |
How it works
Exposure is applied in scene-linear space (before the gamma/tone-mapping boundary), as a multiplicative gain: each stop doubles or halves brightness. If you also have the combined Adjustments filter's own Exposure slider active, the two are summed into a single gain rather than applied twice, avoiding double-processing.

Adjustments includes its own Exposure control alongside Highlights, Shadows, and more in one panel.
