If someone wants to improve the quality of the picture without unlocking the bootloader and install GCAM, you can try the modified chambermiui9DenoiseOFF.upd.apk
Install as a normal apk parallel to the drain chamber. I used it earlier Redmi Note 4, and is now used on the Redmi Note 5 for a photo.
In the settings you have disable shumodava, Zero Shuter Lag, autofocus before each shot, as well as full manual mode with the ability to manually change the ISO, shutter speed, white balance, focus. Also, there are three modes of HDR: Auto, Pro and Live (well, Off - disable HDR) and it seems to me HDR works better than stock. Sharpness settings recommend to put on the Lower (very low).
Below is a comparison of crop 1000x1000 pixels 100%:
Maud turned off shumodava HDR
Sharpness settings in both cases on the Lower (very low).
