This video (in thai) shows off some of the Nokia Lumia 830′s Lumia Denim Camera options. Above screenshot shows the HDR Dynamic flash option where you can feed in the flash to just how you want it.
Something very cool and very welcome is manual focus during video. It’s not tap to focus (which would also have been welcome, like on 808) but actual manual focus so we can now record videos with “pull focus” where you change the focus subjects gradually. This should also eliminate that hunting pulsing video recording phenomenon.
Note how white balance and focus can be changed during video recording.
I’m not sure if that is the video recording as later we see opening of Nokia Camera via the MS Camera app (lens picker) and the video manual modes aren’t available during recording.
Any translations would be welcome.
I’m sure there’s also some possible other interesting things there but now got to dash.
