Does HDR (high dynamic range) work, as of 3.2.1?

Question in title. Is HDR supported right now? I find conflicting information about it on TJC.

  • Recent release notes mention that "White balance and HDR (of the camera) do not work" under "Known issues specific to Xperia 10", so one would presume that it works on the Xperia X and XA2, otherwise it would be mentioned there, too. (Previous phones do not have the required hardware support, as far as I understand.)
  • On the other hand, this question asking about HDR support is still open.
  • HDR is quickly mentioned in the 3.2.0 changelog under models with codenames discovery, voyager, and pioneer (what models are they exactly?):

[vendor/qcom/opensource/camera] QCamera2: Increase maximum BLOB buffers for HDR.

  • Piggz' Advancedcamera has a "HDR mode". I tried it on an Xperia X, and it does not seem to work (it takes a picture, but it seems like a normal picture and not a HDR one).
  • I see nothing mentioning HDR in the standard camera app.

XA2: yes. But I can't tell how well. I am not satisfied with the quality in general.

HDR is supported in some devices' camera drivers as a 'scene mode'. For Sailfish 3.0.2, Adam Pigg, the author of the Advanced Camera app, contributed to the Sailfish Camera middleware the capability to discover which scene modes are available (as well as other modes such as focus) so that apps can advertise HDR mode when it's available.

Unfortunately it doesn't always work very well. As you saw in the changelog, it was crashing on the XA2 models (discovery, voyager, and pioneer) until 3.2.0, and it's not available at all on the Xperia 10 yet. It might appear in the stock Camera app in the longer term once it's reliably stable, but for the moment it's available in advanced-camera and any other third party camera app that can query and set the scene mode.

HDR is the least of the cameras app problems sadly.

like it actually taking a picture way after shutter animation plays?

If taking an HDR picture with advanced camera doesn't produce anything different, then no it doesn't work on that device.

Advanced camera works by querying the android camera hal for supported modes, and creating options to use them. Jolla camera app doesn't have any advanced functionality like that
