ZSD has been provided for assistance, which generally stabilize the shot taken by the camera
HDR - High-dynamic-range imaging (HDRI or HDR) is a set of methods used in imaging and photography to capture a greater dynamic range between the lightest and darkest areas of an image than current standard digital imaging methods or photographic methods. HDR images can represent more accurately the range of intensity levels found in real scenes, from direct sunlight to faint starlight, and is often captured by way of a plurality of differently exposed pictures of the same subject matter ...... hit thanks if i helped u

It is boring to always use the auto mode in camera so let's try the manual mode and have greater quality pictures, which is better than auto mode.
What is manual mode ?
Manual mode is one of the main settings on your camera, and it lets you manually control shutter speed, white balance, manual focus, and ISO in most. These three settings work together to control the how bright or dark your photo is (known as exposure), as well as change the overall look of the image.
What is ISO ?
In photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds.
What is Shutter Speed ?
In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.
What is White balancing ?
White balancing is a process in which a camera will attempt to detect the type of white light largely visible in different environments. This is typically utilized to account for different light sources (fluorescent, incandescent, etc.), as well as different weather types and times of day (overcast, sunny, sunset, etc.). White balance generally focuses on collecting the proper temperature of white light in a scene, which ranges from cold (blue-tinted) to warm (orange or gold-tinted).
This is one setting that is often best left on automatic settings, unless the viewfinder suggests that the automatic white balance is obviously wrong. Of note, RAW images will have to be manually white balanced in post-processing, as RAW shooting will not modify the white balance in-camera.
What is Manual Focus ?
Manual focus controls are a more recent and much-appreciated addition to the control suite of manual smartphone photographers. Most camera apps features a simple and intuitive circular slider which can be used to accurately set focus manually in lieu of the jumpier and imperfect auto-focus, something which is often exaggerated when trying to take photos of close subjects. If you want to take a closer pic of something very near try macro focus.
What is Manual exposure ?
manual exposure is a small supplement to ISO and shutter speed settings, and it is one of the rarer manual settings one will find in smartphone camera applications. If a combination of shutter speed and ISO produce an unsatisfying image, manual exposure is often offered as a way of tweaking the brightness of an image in-camera. It can quite easily be replaced by simply modifying brightness after taking the photo, but it can sometimes be more efficient to get the image right the first time.
What do we have in our Lenovo P2 :
I had Camera api2 activated and snap camera hdr+ and oneplus 5 camera apps.
Shutter speed
Minimum 0.68s maximum 1/96423s
ISO
Minimum 100 Maximum 19200
Verdict approximate values
In low light condition
Higher ISO [ 500 ~ 19200 aprx] + Higher shutter speed [0.68 ~ 1/200 aprx]
In heavy light condition
Lower ISO [below 500 aprx] + Lower shutter speed [1/200s ~ 1/96423s aprx]
Camera Api2 advantages
Raw image capture support
In depth manual mode control
Enable camera api2

It's like this with all the camera apps that have avaible the raw format
At first I was thinking that the problem it's present because I usa a micro sd, but the image gets mad even without it.
I'm on the last lineage build by Higway Star

Only the bug in camera driver can make mess like this.

So it's a rom's related problem?

Same issue on stock s244, with every app.
Also, I've seen many others

Maybe due to changing roms in mobiles the camera driver can get into buggy, not confirmed yet.
If you want Camera with Raw capture try "snap camera HDR" with force HAL1 enabled in-app setting.
If you looking for completely manual configuration try camera api2 ON in-app setting.
[camera api2 HAL3 vs HAL1 screenshots]
I can't find force hal1, sucks.
At least the manual controls it's a very sweet thing

Did you check it out properly? It is in-built in app itself.

I have check the same option that you show in your screen shot, but maybe it's because I have the trial version

With camera api2 raw fails as it is not supported in P2 right now. But without camera api2 or with Hal1 enabled you can capture raw image in DNG format.
I have had the practice of stacking photos in photoshop to increase the spacial resolution and increase tremendous detail in photos taken from my DSLR. I Want the same to be implemented on android but how?
I know there is an app called Camera super resolution on the play store that worked on limited phones. It worked on my oneplus 2 but the way it was implemented just didnt look great as it just enalarged the pic and the stacking used to work seldomly and even when it took 1 single pic it used to enlarge it 4 times.
I took some photos using my oneplus 6 consecutively handheld and stacked them in photoshop and the results are beautiful. Less noise and more detail. The oneplus 6 has the Snapdragon 845 so the stacking should almost be in real time as anyways the camera app stacks photo exposure for hdr.
So my question is can anyone implement this photoshop stacking feature on android. Please............
How the Kirin 970 uses Handheld Super Night Mode to Take Better Photos at Night
When it comes to smartphone photography, the most challenging shots are always going to be night shots. Situations with limited light most often result is grainy unusable photos for devices with weaker cameras. The Kirin 970’s AI chip helps to solve this issue with “Handheld Super Night Mode”.
One way to achieve better night shots is to set your phone on a tripod and let your camera use a longer exposure and higher ISO. This is a bit inconvenient as most people obviously wont be walking around with tripods. To solve this issue, Honor uses the Kirin 970 to add “Handheld Super Night Mode” to their phones. This mode lets you take better night shots without having to setup any equipment.
Handheld Super Night Mode works by using powerful AI algorithms, and the quick processing ability of its Kirin 970. There are several techniques used to enhance your night time photos.
AI Detection of Handheld State
One of the key factors of Handheld Super Night Mode is how the phone uses the AI chipset to detect any hand-held jitter of the phone. To realize accurate and efficient detection, the AI system collected and analyzed tens of thousands of data records reflecting different types of photographers and their camera and tripod usage methods, designing a machine learning logic to understand their habits. As a result of implementing this massive amount of data, the Kirin 970 is able to detect when Handheld super night mode is needed in 0.2 seconds. Using this data, the average users is now able to take better night shots without having to use a tripod.
AI Photometric Measurement
The AI photometric measurement system controls the camera’s light intake. After you tap the shutter button, The AI will automatically set the exposure and number of frames based on the lighting scenario, brightness of the preview image, distribution of light sources, and jitter.
AI Image Stabilization
After all of your frames are captured from your night shot, they are merged into a single image. It is common that surring this process, night shots often turn out blurry. To avoid this, before the synthesizing process takes place, the AI the clearest frames and discards any of the bad ones. The clearest frames are used as the standard for the image, while the other frames that the AI has not discarded are automatically aligned. The AI-powered Kirin 970 chip detects feature points within each frame, matching these points and aligning them to to produce the cleanest image possible.
Image synthesis
The final step in Super Night Mode is image synthesis. For this step, customized algorithms have been computed for the AI system to increase the number of short-exposure frames in bright areas to avoid overexposure and the number of long-exposure frames in dark areas to improve detail retention. Frame differences are detected pixel by pixel. If differences are large, AI determines that alignment failed around the edges and conducts correction and repair to ensure the edge regions are still crisp and sharp enough after synthesis. Noise reduction is performed on multiple frames, thereby improving the image’s signal-to-noise ratio, and achieving a clearer, cleaner, and brighter night shot.
