Preview-only exposure adjustment (non-destructive)

Description:

I would like to request a simple way to temporarily adjust exposure in the preview, purely for evaluation purposes.

This would not be an editing feature and should not affect the exported DNG in any way—only the on-screen preview.

Proposed behavior:

  • Add temporary exposure controls for preview only (e.g. << < > >> buttons, similar to Lightroom Classic)
  • Adjust brightness by small/large increments (e.g. ±0.3 / ±1 stop)
  • Reset automatically or be ignored at export
  • Clearly labeled as “preview only”

Why this is useful:

When working with underexposed images, it is difficult to evaluate:

  • noise after shadow recovery
  • fine detail (e.g. feathers, textures)
  • how well the file will hold up to exposure adjustments later

Currently, this requires exporting the DNG and opening it in another application just to test exposure.

A temporary preview adjustment would allow faster and more accurate evaluation directly within PureRAW.

Scope:

This is not a request to add editing capabilities to PureRAW—only a visualization aid to better assess the processed result.

Summary:

A lightweight, preview-only exposure adjustment would improve usability without changing PureRAW’s role as a preprocessing tool.
