Yes

Description

The image processing functions of Hugo seem to strip out the necessary metadata to display an image with High Dynamic Range (HDR).

When I open the source image in Google Chrome, the image shows correctly in HDR. When I view the same image on a site generated from Hugo, it is displayed normally / SDR.

I'm not an HDR expert, but from what I understand, Google's Ultra HDR (used with Pixel phones) stores the HDR data in XMP metadata in the image. I believe there are also "Gain Maps" embedded in the image.

Additional Info

Here is a source image you can test with: test image

This is from Gemini:

• Android's Ultra HDR Image Format: This format uses XMP metadata to define multiple images and their relationship to create the HDR image. Details
• XMP Metadata: A common method for storing additional data in images is using XMP (Extensible Metadata Platform) metadata. This allows for the storage of structured information within the image file.
• Gain Maps: Some HDR formats use gain maps to represent the difference between the HDR image and a standard dynamic range (SDR) image. This information is embedded alongside the main image data.
