The shutter of the camera on the P20 opens exactly 4 seconds and the information is collected for sharp images. As shown in the image above, you can also see photos taken with P20 that clearly see the branches, the sky is not seeded and the saturation is also better.
Photos taken with P20 (left) have a clear light and the Total logo is also clearer
Do not be afraid to add layers to the image for sharpening and noise reduction, so photos taken with P20 lose a bit of nature. What is notable is that despite opening 4 seconds, Huawei's algorithm is smart enough to fix moving objects.
It doesn't interfere, assesses the good exposure and reflects the pyramid more properly (Huawei image on the left)
In terms of white balance, maybe Pixel 2 XL will be a bit overwhelmed by Google's HDR processing. What Huawei can do is probably between over-sharpening like LG and keeping honesty like Google.
Overall, it's hard to judge the location, but both the Huawei P20 Pro, the Google Pixel 2 XL and the Galasy X9 all have decent cameras for low-light photography.
