hi guys, just want to ask if you can recommend a gcam mod for my 3XL. i really want to try it. thanks and more power
Install this first:

Then this:

Works perfectly on my Pixel 3XL running Graphene (without GOS' added Google services addons)

It is shocking what Google is doing with the Pixel 6 Pro. Multiple people already noticed that the Pixel 6 Pro often chooses digital zoom instead of the periscope camera. Here's an example that someone posted:
Pixel 6 Pro: camera app chooses digital zoom
Pixel 6 Pro: camera app chooses periscope camera

Version: HDR+ 1.0.403259735zd according to the exif data

The light conditions are not bad at all and the periscope image is much, much better. Also note that the periscope camera captures more light per time from objects than the main camera (see below).
Google really needs to give us a setting that forces the periscope camera. This behaviour is ridiculous.

Other sample images from other people also strongly indicate that Google ignores the 50 megapixel or 48 megapixel mode of the sensors. This means that the 4.3x periscope camera is replaced with a 4.3x crop from the 12.5 megapixel mode, if the camera app refuses to use the periscope camera. This leads to an effective resolution of 12.5/4.3² = 0.68 megapixels! This is also the reason why the maximum zoom setting of the Pixel 6 (not Pro) is only 7x (like the Pixel 3), it crops the sensor in its 12.5 megapixel mode.

Note that the periscope camera captures more than twice as much light per time from distant objects as the main camera (when you don't adjust the distance) because the effective diameter (entrance pupil diameter) is 19mm /3.5 = 5.43mm , whereas the main camera only has 3.68mm.
(Don't confuse the effective diameter with the f-number, which is related to light per time per unit area of the sensor. The Hubble telescope has a 57600mm f/24 objective.)
The only problem is read noise because the periscope camera delivers 17.5 times as many pixels per object as the main camera. This causes more read noise per object, but read noise is only relevant in low light conditions (for example completely dark room) or in very dark shadows. In decent light conditions, read noise isn't relevant and the periscope images would look less noisy than a crop of the main camera sensor because the periscope camera captures more light per time from an object than the main camera. Indeed, the periscope image isn't noisy at all.

See
at 4:13, a review confirms that the Pixel 6 Pro has this issue.

It's also disappointing that Google still hasn't fixed the issue that Night Sight takes slightly blurry photos due to a too long exposure time per frame (often 1/3s-1s on my Pixel 3a in low-light conditions, I much prefer Pixel 3a's HDR+ enhanced, which is a fast Night Sight mode and chooses 1/5s per frame), even though the Pixel 6 captures 2.5 times as much light per time as the Pixel 5. For example see
at 13:56.

or
at 12:14

The Night Sight mode of the Pixel 6 even takes longer than the Night Sight mode of the Pixel 5, see
at 9:20

So, one can only hope that Google brings back HDR+ enhanced.
It would be also nice, if the camera app didn't reset the timer whenever you open it. A timer is quite important for sharper handheld photos, I'd use it all the time. Obviously, it is not ideal, when the camera captures the frames while you press the shutter button. This causes more blur. That's why HDR+ enhanced always used a timer secretly.

Hello, I've installed this on my Pixel 4.
This is my first time installing this way! So I am not sure about 2 things, it'll be great if you (or anyone here) clear my doubts.
1. Pixel 4 uses Neural Core to process photos after capturing, so if I install this way, does it still use Neural Core to process?
2. When gcam updates arrive in the play store later, can I still update via play store? Will there be any issues?
TIA

Hi 1. it will work the same 2. The update will proceed normally.

Techradar's full resolution sample images indicate that the Pixel 6 Pro occasionally even crops the ultra wide angle camera sensor instead of using the main camera sensor! See https://www.techradar.com/uk/reviews/google-pixel-6-pro-review#cameras
According to the exif data of the "Main camera" image (image 2 of 10), it has used a crop from the ultra wide angle camera! That's why the "2x" image (image 3 of 10), which did use the main camera, has far more detail.
And again there is also a "4x" image (image 4 of 10) that used a crop of the main camera sensor, this really must be a bug.

The Google camera app software of the Pixel 6 Pro and Pixel 6 seems to have a huge issue regarding noise reduction. See the full resolution wide angle and ultra wide angle comparisons between Pixel 5a and Pixel 6 , Pixel 6 Pro at https://www.techradar.com/uk/featur...-stack-up-against-apple-and-samsung-flagships
Pixel 6 Pro main camera: https://cdn.mos.cms.futurecdn.net/Pyy9dzh8CcfvFyBodFKZER.jpg
Pixel 5a main camera:

The 6 Pro applies an extremely aggressive and patchy amount of noise reduction to the lawn. The 5a looks much better here, even though the exif exposure time of the 5a is much shorter. Even the Pixel 6 performed better than the Pixel 6 Pro (main camera comparison) despite the same HDR+ version in the exif data. Probably just coincidence.
In the second comparison (ultra wide angle), both the 6 Pro and the 6 perform much worse than the 5a. Also look at the roof!

It's unexplainable. The Pixel 6/6 Pro main camera should capture much more light than the 5a. Maybe, the Pixel 6/6 Pro trigger HDR+ with bracketing less frequently, but the noise reduction is patchy, so you can see in the areas that are sharp that there is no need to apply an aggressive amount of noise reduction. Also, Google phones without HDR+ with bracketing don't apply a patchy, aggressive noise reduction either, even though the hardware captures even less light.

Too bad this is dead. Loved it on my Pixel 3 and would now love it even more on my Pixel 6. When I checked the DNGs vs the jpegs, I was flabbergasted. The noise reduction and sharpening are way too aggressive again. I would love to tone them down, as I did on my 3.

Just take the attached example. Left is a quick Lightroom mobile edit of the DNG, right is the out of cam jpeg. The fur is way too harsh and the jpeg engine even lost part of the whiskers!

I have the 6 Pro. Note that in most cases, the raw files help, but in some cases even the raw files are ruined. In some cases, the aggressive noise reduction is also applied to the raw files and in some cases, blurry spots from the jpg appear as extremely noisy, colorful, unusable spots in the raw file despite perfect (!) light conditions.
The jpgs also apply far more color noise reduction in extreme low light conditions. In extreme low-light conditions, a Pixel 3a in HDR+ enhanced mode + high brightness slider setting can deliver much better colors than the Pixel 6 Pro in its HDR+ mode + high brightness setting. The result can look as if one uses the maximum color noise reduction setting from Lightroom, but when I look at the raw file, it is totally unnecessary to apply so much noise reduction.
And Google's "super resolution" zoom is rather an anti-resolution zoom. It ignores the 48 megapixel mode of the tele camera and will still apply a huge amount of noise reduction, so occasionally, you can actually get better tele results with certain dedicated cameras that even don't capture more light per object than the periscope camera and don't have more pixels per object than the periscope camera in the 12 megapixel mode of the sensor.

And regarding the 4x zoom issue: Indeed, the 6 Pro often chooses digital zoom from the main camera instead. In nearly all cases, the digital zoom result is worse than the periscope result (I have compared the results). Only in extreme low-light conditions without bright light sources, the periscope result can be worse.

The best feature of the 6 Pro camera are the sliders, so you can expose for the highlights without getting a dark photo and also adjust the white balance. Sadly, they haven't fixed the issue that exposing for the highlights will often reduce the exposure time instead of the analog gain. Then you can get very noisy shadows, especially with the periscope camera. The exposure time is often too short (for example 1/100s) for this purpose. The only solution is Night Sight, but Night Sight often chooses a too long exposure time per frame in low-light conditions (for example 1/2s, that's too long), so the best solution would be the old HDR+ enhanced mode, which was a fast Night Sight mode, but Pixel 4/5/6 don't have HDR+ enhanced.

The lack of an HDR+ enhanced mode also removes Google's biggest advantage: multi frame noise reduction
The HDR+ mode (not Night Sight) works so fast that there is simply no time to capture multiple exposures in low-light conditions, if the exposure time per frame is 1/3s. Therefore, HDR+ raw files don't necessarily have a better noise performance in low-light conditions than single frame dng files from a 3rd party app (I compared them).

Could you perhaps share your settings that you used on the pixel 3 to reduce noise reduction and sharpening?

    Project Status
    As you may have noticed or seen in my sporadic posts here, Camera PX development has been non-existent for quite some months now. This is mainly due to a lack of substantial updates within Google Camera, but also due to lack of interest in the project as other things in our lives have become more important. As each new Google Camera version is released, the modifications have to be re-done from scratch so this would take quite some time as we only get to do this in our "free" time after work and spending time with our families. We do hope the Pixel 5 release brings some new/interesting things to the table but that is yet to be seen, and the passion to restart the project is also yet to be seen. For now, we are releasing a minor update to "support" Pixel 4a's but since Google Camera 7.2 was not built with Pixel 4a's in mind, you may notice a quality difference than your stock camera.

    Disclaimer
    This has turned into a collaboration between @back.rider555, @johngalt1 and myself. We do this in our free time, when able, to bring newer Pixel features and mods to your older device.

    Introduction
    This is a Google Camera mod for the Pixel phones. The main goal is to bring newer features to older Pixels, where possible.

    What is Google Camera (AKA GCam)?

    Google Camera is the camera app for the Google Nexus and Google Pixel phones. It is not designed or intended to be run on other phones.

    What is HDR+?

    Basic: HDR+ is Google's proprietary image processing routine, and is more than just traditional "HDR' modes. HDR+ employs image stacking to control exposure, and also to preserve details, reduce noise, increase sharpness, etc. It is an all-in-one package.

    Advanced: https://ai.googleblog.com/2014/10/hdr-low-light-and-high-dynamic-range.html

    Google Camera Features

    Pixel 1
    • Zero Shutter Lag (ZSL) HDR+ - The Pixel 1 introduced ZSL HDR+ which means when you open the camera, the system utilizes the Hexagon DSP to constantly buffer frames and marks the time slot of when you pressed the shutter button.
      * -- Quote from Marc Levoy via The Verge:
      "The moment you press the shutter it's not actually taking a shot — it already took the shot," says Levoy. "It took lots of shots! What happens when you press the shutter button is it just marks the time when you pressed it, uses the images it's already captured, and combines them together."
      It's a major usability improvement on the HDR+ mode in last year's Nexus 6P and 5X. "What used to happen last year is you'd press the shutter button and you'd get this little circle going around while it captured the images you need for the burst; now it's already captured those," says Levoy. "And that's big, because that means that you can capture the moment you want."
      * -- https://www.theverge.com/2016/10/18/13315168/google-pixel-camera-software-marc-levoy

    Pixel 2
    • Portrait Mode - Simulates bokeh for improved subject separation from the background. The front camera of the Pixel 2 only provides Portrait Mode when a human face is detected, and the rear camera can work on an object, an animal, a human, etc because it uses information from the Dual Pixel PDAF sensor to detect depth. Google Camera ports for non-Pixel phones can NOT do this so all ports for non-Pixel phones utilize the front camera technique for both front & rear (which means all ports for non-Pixel phones can only properly apply bokeh when a human face is detected).
      * -- Advanced read: https://ai.googleblog.com/2017/10/portrait-mode-on-pixel-2-and-pixel-2-xl.html
    • Motion Photos - Provides short clips of moments before and after you take the photo.
      * -- Advanced read: https://ai.googleblog.com/2018/03/behind-motion-photos-technology-in.html

    Pixel 3
    • Top Shot - When Motion is set to Auto or On, Pixel will recommend a better photo to you if it detects one. Like if you captured a photo when someone blinked.
      * -- Demo:
    • Photobooth - Automatically capture a photo when Pixel detects a silly face or a smile.
    • Super Res Zoom - Enhances zoomed picture quality by purposely shifting the camera module using OIS (Pixel 3 only) to gather more data.
      * -- Advanced read: https://ai.googleblog.com/2018/10/see-better-and-further-with-super-res.html
    • Motion Metering - On the Pixel 3 Motion Metering is used in the "default photo mode" to detect subject motion and if it detects enough motion, Pixel will shoot with a faster shutter speed to reduce subject blur. The Pixel 1 and 2 get to use this in Night Sight only.
      * -- Further reading (about 1/3 down the article): https://ai.googleblog.com/2018/11/night-sight-seeing-in-dark-on-pixel.html
    • Synthetic Fill Flash - Pixel 3 will brighten faces in selfies.
    • Tracking Autofocus - Tap on a subject or area to keep focus when the subject or phone moves.
    • Learning Based White Balance - Google's attempt to fix white balance for low light photos. Used in Night Sight and HDR Enhanced on the Pixel 3.
      * -- Further read (about 1/2 down the article): https://ai.googleblog.com/2018/11/night-sight-seeing-in-dark-on-pixel.html
    • Portrait Mode Learned Depth - Pixel 3 improves the rear camera Portrait Mode depth detection for more consistent and more pleasing bokeh.
      * -- Advanced read: https://ai.googleblog.com/2018/11/learning-to-predict-depth-on-pixel-3.html

    -Add Xlib2 (another reduced contrast option) and modify to support Pixel 3 Portrait bokeh on Pixel 2
    -Add Portrait and Night Sight App Shortcuts from back.rider555

    Known Issues on Android 8.1:
    -Tapping to focus breaks autofocus. Exiting camera or switching modes/cameras fixes this.
    -Night Sight will crash the very first time you use it after installation. It appears to run just fine after that until you Clear Data of the app.

    P3v9.1_GoogleCamera_6.1.021.apk
    -Disable HDR+ mode resetting for Pixel 1 when opening Camera
    -Add "reduce contrast" option which loads a custom lib by Savitar to reduce black crush a little bit. I have not tested in all conditions. Feel free to test at your own discretion and provide your thoughts with comparison pics.

    P3v9_GoogleCamera_6.1.021.apk
    -Revert default color accent to Google Blue by popular request
    -Fix HDR+ mode resetting for Pixel 1
    -Exif fix (big thanks to @Arnova8G2 for helping)
    -Fix Night Sight for Android 8.1 (big thanks to BSG)

    Known Issues on Android 8.1:
    -Tapping to focus breaks autofocus. Exiting camera or switching modes/cameras fixes this.
    -Night Sight will crash the very first time you use it after installation. It appears to run just fine after that until you Clear Data of the app.

    P3v8.6_GoogleCamera_6.1.021.apk
    -Change default color accent to Google Green
    -Add P3 Mod Settings>Permanent Night Sight Suggestion
    --Provides an always on button to enter Night Sight
    -If P3 Mod Settings toggles are changed, the camera will restart automatically to apply the changes (be careful if HDR+ is Processing) (thanks @fu24 / namok)
    Known Issues on Android 8.1:
    -Tapping to focus breaks autofocus. Exiting camera or switching modes/cameras fixes this.
    -Night Sight will crash the very first time you use it after installation. It appears to run just fine after that until you Clear Data of the app.
    -Night Sight viewer is black. There is a fix for this but then it requires Flash to be set to Auto/On for it to work properly. I don't use Flash ever so this is not a good option to me at the moment. I opted for the black screen until a fix can be found. Thanks for understanding. Wait until the focus ring is gone, or choose your focus in the Focus Option on the top right, then click the photo.

    P3v8.5_GoogleCamera_6.1.021.apk
    -Cleaned up P3 Mod Settings. Settings not relevant for Android 8.1 are removed, and PVC toggle is removed for non-Pixel 2/3.
    -Add P3 Mod Settings>HDR+ Enhanced for Portrait toggle. This increases dynamic range, at the cost of shutter delay. Force close the app is required for the setting to change. (Credit to BSG for the method)
    -Tried to adjust some stuff for Wear remote shutter support but I need a proper log if there's issues still.

    P3v8_GoogleCamera_6.1.021.apk
    Must uninstall old version due to signature change.
    -Support for Android 8.1 (referenced BSG's latest versions)
    -Settings>P3 Mod Settings
    --Toggles to switch Photo viewers (Classic or Google Photos), Enable Pixel Visual Core for ZSL HDR+, Disable Learning Based AWB in HDR Enhanced, & Disable Tracking Autofocus. The last 2 options only work on Android 9, so the toggles don't do anything for Android 8.1
    Known Issues on Android 8.1:
    -Tapping to focus breaks autofocus. Exiting camera or switching modes/cameras fixes this.
    -Night Sight will crash the very first time you use it after installation. It appears to run just fine after that until you Clear Data of the app.
    -Night Sight viewer is black. There is a fix for this but then it requires Flash to be set to Auto/On for it to work properly. I don't use Flash ever so this is not a good option to me at the moment. I opted for the black screen until a fix can be found. Thanks for understanding. Wait until the focus ring is gone, or choose your focus in the Focus Option on the top right, then click the photo.

    FAQ
    Q: "I already have a Pixel, why do I need to use a GCam mod?"
    A: Here are the added benefits of Camera PX:

    • All Pixels:
    • Ability to choose Camera, Portrait, or Night Sight as the default mode
    • Custom Lib options to reduce black crush, improve details, and/or increase clarity
    • Ability to choose 4K Time Lapse quality
    • Ability to choose zoom level in Portrait Mode of 1.2x or 2.0x (for the rear camera)
    • Ability to choose to enable HDR+ Enhanced for Portrait Mode
    • Option to have quicker access to Night Sight by "permanently" adding the little message at the bottom regardless of measured light (admittedly it disappears if you capture a photo in regular mode)
    • Option to increase shutter speed and frames in Night Sight for potentially "better" Night Sight photos
    • Option to disable the "Learning AWB" in HDR+ Enhanced/Night Sight
    • Option for manual shutter speed & ISO
    • Face warping is completely disabled

    In addition to the above, these are the added features for specific devices (when compared to the stock app):

    • Pixel 1:
    • Portrait Mode (only when a "human face" is detected, does not work on objects/animals like Pixel 2, 3, 3a)
    • Removes the HDR+ mode reset on launch or when leaving settings
    • Synthetic Fill Flash (brightens faces when there is a strong backlight)
    • Motion Photos & Top Shot (if you have the correct Google Photos APK installed)
    • HEVC option
    • Photobooth
    • Adds focus button in Night Sight (Auto/Near/Far)
    • Tracking Autofocus in Photo mode
    • Super Res Zoom sharpening algorithm

    • Pixel 2:
    • "Learned Depth" for Portrait Mode which provides, usually, a more accurate depth detection and more pleasing bokeh
    • Synthetic Fill Flash (brightens faces when there is a strong backlight)
    • Top Shot (if you have the correct Google Photos APK installed)
    • HEVC option
    • Photobooth
    • Adds focus button in Night Sight (Auto/Near/Far)
    • Tracking Autofocus in Photo mode
    • Super Res Zoom sharpening algorithm

    • Pixel 3:
    • -Adds 60ps option to top bar in Video mode

    • Pixel 3a:
    • Synthetic Fill Flash (brightens faces when there is a strong backlight)

    Q: Do I need to change any settings?
    A: This mod is optimized for the Pixels to run without changing any settings. There are some advanced settings in P3 Mod Settings. Experiment at your own will.

    PXv3.0_GoogleCamera_7.2.010.apk
    Mirror: https://www.celsoazevedo.com/files/android/google-camera/dev-cstark27/

    As tested on a Pixel 2 (but mods were applied in a universal manner):

    * Enable Astro mode for Pixel 1 & 2 (instructions (thanks @ins0mniac): https://forum.xda-developers.com/showpost.php?p=80678229&postcount=1507)
    * Enable Focus options in Night Sight (along with "infinity" - may be same as far)
    * Modded lib for Learned Depth in Portrait Mode (Pixel 2)
    * Enable Super Res Zoom while zoomed or in Night Sight (no zoom required) - this is like Pixel 3 stock
    * Enable auto timer (photobooth), it's in the selfie camera in the Timer options
    * Enable synthetic fill flash for Pixel 2 and enable SFF in Camera mode for 3a

    More advanced options/features to come later, please don't ask about them...For now it's a quick mod for those who want an "upgraded stock"-like app for their Pixel 1 or 2.

    PXv4.0

    Attention Pixel 2 users (and maybe Pixel 1, 3, 3a): it has been discovered that the Super Res Zoom Always On toggle that is enabled by default can cause undesirable effects in shadows and high contrast areas. It is advised to disable this option until an adjustment comes with a newer APK to separate the (2) included functions.

    Hello guys. So this one is a bit exciting because @back.rider555, @johngalt1, and I were able to collaborate on this and deliver a mod with almost all previous features, some new ones, and as much support as we could muster and test for.

    • Requirements:
    • OS: Android 9 or 10
    • Device: Google Pixel series (some other devices may work, but are not supported in the traditional sense - please do not post in this thread about non Pixel devices)




    • Changelog: Initial release based off Google Camera 7.2.014. Supported features are shown in the image below. "Default" means your stock app already has this feature; "Y"/"OK" means this was added to the listed device; "N/A"/"Disabled" means the feature could not be enabled for the listed device, either because of unsolved crashes, missing hardware, or messing up a fundamental function.
      An extra shout out to marcello for the initial Lib Patcher, further implemented and tweaked by johngalt1, and Urnyx05 for some Android 9 fixes.

    Some notable features:

    Hold the camera switch icon for quick access to settings.

    Lib Patcher: this can be used to modify certain parameters like sharpness and noise removal amount. The settings here will depend on what you like, there is no "best" setting. Please read the info in "Learn More" within the app under the enable button.

    The max exposure setting can be adjusted but does not mean it will always choose this shutter speed. GCam will automatically detect certain parameters and choose the most optimal shutter speed. A stock Pixel 1 supports up to 2s, Pixel 2 up to 4s, Pixel 3/3a up to 12s, Pixel 4 up to 30s. Using Magisk Modules in post #2 can make this longer, but Google decided on 16s due to star trails and the perception of blur being about the limit around 16s. By default, this APK selects 12s for Pixel 3 and 3a as those devices support higher exposure times than the stock APK allows for Astro.

    There are 2 buttons that can be added to Night Sight. Forced Astro mode, and Light Painting Mode. Use a tripod or tripod-like structure for Light Painting Mode or if the scene is really dark. Handheld will not be good.
