TwinPeaks is a specialized histogram visualization that shows the distribution of color values as a luminous trace, making it easy to identify peaks and clusters in your image data.

## Overview

Unlike traditional histograms that show bar graphs, TwinPeaks displays the data as a continuous, glowing trace. This makes it easier to:

* Identify subtle peaks in color distribution
* See the relationship between different tonal regions
* Spot clipping at highlights or shadows
* Visualize the overall "shape" of your image's tonal distribution

## Interface

The scope displays RGB channels as overlapping traces, with intensity indicating the concentration of pixels at each value.

## Settings

Access scope settings via the hamburger menu (☰) or right-click on the scope.

| Setting    | Description                         | Default |
| ---------- | ----------------------------------- | ------- |
| Channel    | RGB combined or individual channels | RGB     |
| Brightness | Trace brightness/intensity          | Auto    |
| Scale      | Linear or logarithmic display       | Linear  |

## Use Cases

### Exposure Analysis

The shape of the TwinPeaks trace quickly reveals:

* **Underexposure**: Peaks bunched toward the left
* **Overexposure**: Peaks bunched toward the right
* **Well-exposed**: Peaks distributed across the range

### Highlight and Shadow Detail

Look for peaks at the extreme edges:

* Peaks touching the left edge indicate crushed blacks
* Peaks touching the right edge indicate clipped highlights

### Color Balance

Compare the position of RGB channel peaks:

* Aligned peaks indicate neutral tones
* Offset peaks indicate color casts

## Tips

* Use alongside the standard Histogram for different perspectives
* The trace brightness helps identify where most pixels are concentrated
* Logarithmic scale can reveal detail in sparse regions
