What does HDR stand for?

| Type | Initialism |
The initialism HDR stands for High Dynamic Range. In photography, it concerns representing a wider range of brightness, from dark areas to bright highlights.
Merging exposures and displaying an HDR image are related but different operations. An HDR editing workflow can include output prepared for an HDR display or a rendering for a standard dynamic range display. The label does not prove that every screen will show the same appearance. Exposure merging is one HDR technique, not a requirement implied by the letters HDR.
Meaning in context
- High Dynamic Range
- The brightness range is the concern, rather than a synonym for stronger color saturation.
- Photography context
- Exposure merging can produce HDR image data; the output and viewing display still affect how that data is presented.
Practical examples
Describe the capture step
- Before
HDR just means turning up saturation.
- After
We merged exposures of the room to retain information in both the windows and the darker interior.
The revised example describes the brightness problem and the operation used to address it instead of using a color adjustment as the definition.
Describe the output
- Before
This HDR export will look identical on every screen.
- After
We prepared an HDR output and will also review an SDR rendering for readers using standard displays.
The revised plan recognizes that viewing conditions matter and makes the intended output clear.
Original illustrative examples, not quotations or reports of actual events.
Use HDR with clarity
Which part of a photo workflow does HDR describe here?
See all guidance
Merge exposures
Explain the bright and dark areas whose information you want to retain.
The window and the dim interior are the two parts we need to preserve.
Prepare HDR output
Identify the intended HDR display workflow and compatible output.
This version is intended for an HDR-capable viewing workflow.
Prepare an SDR rendering
Check the version intended for a standard display rather than assuming identical appearance.
We are reviewing an SDR rendering for the website's standard-display audience.
