EXR Workbench (Preview Build)

Examples

EXR Tool

Read and write OpenEXR images with channel-focused processing and tone mapping controls.

What This EXR Tool Covers

This page defines the OpenEXR workflow surface and will be used to ship decode/encode and channel-level transforms with SEO-friendly documentation.

Supported EXR workflow scope

  • Input focus: OpenEXR sources used in rendering, compositing, lighting, and high dynamic range image workflows.
  • Output scope: EXR-derived exports and preview-friendly outputs for quick validation.
  • Best fit: channel inspection, HDR review, and lightweight format conversion before deeper desktop work.

When to use this tool

  • Inspect EXR files before conversion, delivery, or material ingestion to confirm channel structure and preview behavior.
  • Review tone mapping and per-channel visibility when HDR source data must be validated in a browser.
  • Export EXR or preview derivatives for rendering, review, and downstream texture or lighting workflows.

Related tools

HDR Tool

Use the HDR page when the workflow centers on Radiance .hdr instead of OpenEXR.

UltraHDR JPEG Tool

Switch to UltraHDR when the delivery target is JPEG gain-map content for modern viewers.

How To Convert EXR to HDR

Use this guide when your next decision is whether an OpenEXR source should be exported as Radiance HDR.

Planned Capabilities

  • Load .exr files and parse channel data safely.
  • Export processed EXR outputs with consistent metadata handling.
  • Operate per channel (R/G/B/A) before tone mapping or export.

Planned Workflow

  1. Import EXR source and inspect channels.
  2. Apply channel transforms and tone mapping adjustments.
  3. Export EXR result and optional preview output.

FAQ

Will multi-channel EXR be supported?

The initial scope targets common RGBA flows, with broader channel support staged next.

Is this intended for linear workflow?

Yes. Processing is designed around linear space and controlled tone mapping.

Can EXR and HDR tools share logic?

Yes. Both will reuse a shared HDR image core for transform and preview stages.
