Google led to the new Night Sight function, during the launch of Picell 3 (Reviev), which promised seemingly big improvements in the quality of low-quality photos. Now, the company officially announces this feature for a full range of smartphone smartphones. Unofficially, Night Sight was in the wild for several weeks, and a member of the KSDA Developer Forum managed to change Google's Camera application to allow it to any pixel pixel. Since then, we also had ports for OnePlus 6 (Reviev) and OnePlus 6T (Reviev), and recently we got ports for Ksiaomi's Poco F1 (Reviev) and Ksiaomi Mi 8.
In this article, we will do our best to work out how Night Sight works, what are the odds and how to get it on Google's pixel smartphone.
What is a night view and how does it work?
The main aim of the night shooting mode is to reduce noise and improve the detail in images taken in dark environments. In traditional photography, the easiest way to do this is to use a slower shutter so that the image sensor can take more light. However, without a tripod, blurry movement can become a big problem if you (or even your subject) move even a little. This technique on a smartphone can lead to catastrophic results, as they are almost always used manually.
Go for the night view for the Google Camera app now on Pikel Smartphones
When you see a night view in action, it seems to be pure magic. In reality, he works on computer photography and some machine learning. According to the Google blog post, the main challenge facing the company was to achieve the alignment of all objects in the right frame, since Night Vight essentially employs the technique of matching personnel, such as HDR + and Super Res Zoom. Picell and Picell 2 use a modified version of the HDR + night vision algorithm, while Picellus 3 uses the tweaked version of the new Super Res Zoom algorithm to deliver similar results.
From the moment you press the shutter button in Night Scene mode, the camera captures a series of images quickly in a row. The number of frames shot depends on the amount of light available and whether you are using a handheld or tripod. It can be anywhere from 6 to 15 frames. Pikel 3 and Pikel 2 (Reviev) have the advantage of being able to handle longer exposure frames, as they have Optical Stabilization (OIS) to compensate for vibration, but the original Picel goes to shorter exposure, as OIS is missing.
A few things to point out at this stage – it takes a few seconds for the camera to finish shooting all the frames, during which you will need to be calm. If you move or your object moves, these frames are rejected or your subject may have a slight blur in the last picture.
Once the image is saved, it goes through some background processing in order to correct the white balance and exposure level. Google says it has developed a special Auto White Balance Algorithm based on deep learning that has been trained on Pic 3. Therefore, when comparing images taken with Night Sight on all phones, Pic pic 3 usually has a better white balance. Google himself acknowledges that this algorithm will bring the best results to Picell 3. The company has also customized its tone mapping techniques to get the right balance between delivering a well-lit picture and staying true until the actual time of the day.
How to get to the night view – and does it really make a difference?
If you have any pixel pixels, you should soon see an update for the Google Camera app waiting in the Play Store. If that's not yet, be patient, as Google updates this update in phases, so you should get it at the end.
When your Google Camera app is being updated, open it and go to the More tab, in which case you'll see Night Sight. If you shoot in Auto mode and the environment is very small, you will see a little trace in the viewfinder Try a night view.
The Night Sight function in the Pikel 3 KSL campaign
Taking pictures is pretty easy. All you do is point the camera toward the subject, press the shutter button and hold until the process is complete. You can – if you want – set a timer for three or 10 seconds to start the countdown timing, and exclusive to the Picell 3 series is the option of manual focus adjustment. This other feature is required only if you shoot in dark darkness and the camera can not lock the focus. & # 39; Near & # 39; forcing the camera to focus at about 1.22m, while "Far & # 39; focused on 3.66m and above.
For our landscaping landscapes, we first tried Google Picell 3 KSL, Picell 2 KSL and original Picel with plenty of light. All three generations of the phones did a decent job with details, but in the sky there was still a lot of visible noise, and the shadows were not clearly visible. With Night View, the noise was drastically reduced, giving us much cleaner images. Colors and details in remote objects were also much better defined, and we could see much more in the shadows.

In our test results, you can see that our subject was barely visible when shooting in the auto mode. In fact, that's pretty much what we saw with our naked eyes. But with Night View, as if somebody turned on the lights. The colors, details and clarity of the images are drastically improved, with excellent focus and blurry background.

Night Sight also works for Pikel phones. Here you can also enable the charging light if it is too dark for shooting. For this test, we stood in complete darkness, with the only light that comes from light on the objects opposite us and a little behind the door behind us. As expected, none of the phones could display anything worth sharing when used in Auto mode, but with a night view, the difference was massive. Image quality became even better when we enabled lightening for night vision.

Based on what we have seen so far, the night view looks like a game changer and in many situations it pretty much kills the need for LED flash on your phone. There are several limitations for this feature, for example, it is not very effective in the dark ants, and is best used for still themes.
It's nice to see Google adding this feature to older Pikel phones, but what we really like is that the company opens for OEMs to get involved in their camera applications. It's done with Google Lens and AR labels, so why not Night Vision?
