HDR WCG Viewer

The HDR WCG Viewer enables domain-focused analysis of HDR and wide color gamut content without requiring on-device calibration. It accepts HDR image formats and color-space metadata, then produces a perceptually meaningful preview alongside quantitative metrics for luminance and gamut. Professionals such as photographers, colorists, and QA engineers use it to validate tone reproduction and cross-device consistency before delivery.
Conceptually, the tool decodes the input, interprets HDR metadata (PQ or HLG), converts to a linear working space, applies a tone-mapping operator to simulate display rendering, and maps results into the target gamut. It then computes metrics such as deltaE, gamut coverage, and luminance bounds, and provides a PNG preview for quick review. Advanced controls allow experimenting with tone-mapping curves, luminance targets, and multiple display profiles to support production pipelines.
This tool accelerates review cycles, improves color decisions early in workflows, and reduces the risk of clipping or desaturation when content moves between devices. Use cases include pre-press color checks, color grading validation, and cross-device comparisons. Unique value lies in HDR/BT.2100-aware processing, explicit display-profile simulation, and integrated exports for reporting and automation.
