TwinPeaks
This scope requires a Pro license.
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.

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
