Why does camera two look different?

Add this view from Add scope > Comparison Scope, then choose the input you want to inspect. Use the pane's i button for its in-app reading guide.

  1. Green and magenta Y′ traces separate where the neutral and warm variants differ. The high plateau at left includes the white fabric; the broad middle band includes the gray background and table.
  2. Use Mix, Difference, Split or Side-by-side to make the question easier to see.
  3. Compare the aligned subjects in Waveform or Vectorscope; upper preview and lower graph display choices are independent.

Try it yourself.

  1. Choose two controlled studio variants, or two camera inputs.
  2. Align features, use Match faces for a suitable detected person, or Select objects after local-model setup.
  3. Choose Waveform + Vectorscope to inspect exposure and chroma together. Freeze one input to retain a reference.

Useful controls.

  • Preview and graph palettes save independently. Side-by-side presents complete source views.
  • Hold top-row 1 or 2 over a focused graph for temporary single-source inspection.
  • Match faces aligns eye midpoint and face size. Compatible camera controls can attach beside either input.

Comparison uses the latest available frames. A steady subject helps when capture paths have different delays.
