Lightroom Classic v13, Adobe Camera Raw v16, and Lightroom v7 now support a true end-to-end workflow for capturing, importing, viewing, editing, and sharing images with High Dynamic Range information on High Dynamic Range monitors.
In the past, these applications could capture, import, and merge multiple exposures to create HDR photos but because most devices (monitors, tablets, phones) were only capable of displaying a smaller, Standard Dynamic Range (SDR), they then had to remap the HDR information to be shown on SDR displays.
As HDR displays become more prevalent, Adobe wants to make sure that photographers will be able to take full advantage of the HDR information in their images. With this release – and an HDR display, you can now view, make edits, export to HDR-compatible file formats, and present HDR photos in Lightroom web albums.
If you want to know exactly how HDR works in Lightroom Classic, Adobe Camera Raw, and Lightroom, I would highly encourage you to read this article by Eric Chan “High Dynamic Range Explained“. He has been working on this project for the past two years and explains everything about the new feature in a straightforward, easily digestible manner. He also shows examples of his own stunning photographs that clearly benefit from this new HDR workflow.
