This Fall break, I found that all photos, where took in Los Angeles, on my new phone looked "radiance". But most platforms do not support previewing such photos, so I will put some samples in this post.

Why do we need HDR gain map photos?

HDR stands for "high dynamic range". In general, it means the difference between the lightest light and the darkest dark you can capture in a photo is high. Think about a photo of the sunset, where the sun may be much brighter than anywhere else. In this case, HDR photos can better demonstrate the brightness of the sun. On the other hand, an SDR (standard dynamic range) photo cannot. Since human eyes are super sensitive to brightness, you may feel an HDR photo is much more realistic, even a little bit three-dimensional.

If you want to learn more about HDR gain map photos, I would recommend you take a look at these videos:

Quick HDR Support Test

  • If your display support HDR, you will see a super bright square.
  • If you only see a normal brightness square, your device does not support HDR. This may results in your hardware (display brightness limitation) or software (Browser).
  • If an broken image icon displayed, your browser does not support avif format.

Photo Gallery

Known Compatibility Issues：

  • HDR / Gain Map Photo seems to only work on Chrome Desktop. If you use an incompatible browser, the HDR photos may be invisible or look unusual.
