I note that the P20 Pro has actually three HDR modes:
- HDR as an option. In my opinion the most unnecessary mode, which seems to work at the program level. In a number of scenarios, there is no sense from him.
- RHDR, works only in automatic mode. Significantly more effective to compensate for dark/light areas compared to the previous one. I believe that in this mode, the device makes the gluing of 2 frames with different shutter speeds. The downside is that it does not always work, so sometimes you have to change the EV for “forcing” the RHDR.Most often, I use this particular HDR mode.
- Night mode is probably one of the main advantages of the latest Huawei devices. With this option, it is possible to obtain an acceptable image in the absence of any light sources. The downside is that the process of obtaining gluing from several frames takes 5 seconds, which essentially eliminates the possibility of shooting moving objects. For example, I will also post a photo in this mode.
There is another feature that in the RHDR and Night modes, the device creates a picture with rich colors and overestimates sharpness on the border of objects. But this feature is peculiar to many smartphones that I have seen.
