Huawei P20 pro "Aperture mode"

While the P9 was already equipped with an synthetic aperture more, i.e. blurring the background, effectively, I never used it. With the P9 I shot either in RAW or in monochrome, for which the aperture mode is not available.

In the P20 pro, RAW is still RAW, the image information as recorded by the sensor, things have changed for the monochrome camera. Unfortunately, there is still no RAW data available from the monochrome sensor.

However, next the normal and pro modes, which were already known from the P9, Huawei added the aperture and portrait modes to the monochrome camera.
I have yet to experiment with the portrait mode.

The aperture mode provides some nice results in monochrome.

However, since this is all synthetic and merely based on triangulation of the distance, the algorithm does not handle reflections properly.

reflections on water

As you can see in the image above, curtain in the background is totally blurred, i.e. out of focus, while the reflection on the water surface, the curtain is in focus.

Therefore, when using artificial aperture mode, it is advisable to avoid reflective surfaces.
