Don't see it on the phone, on the Samsung Store or on Google Play... ?

crescent moon night shot 1x and 3x zoom hdr++
(moon is only visible in the zoom shot as I had to walk back to get it in the view)

I tried AGC a couple of time and it's worse than stock in my opinion. Unless you don't zoom at all, but the everything would look fine.

I don't understand why we're still talking about it...

Colors look pretty good to me in this v52 version.

My main concern is, which is not a big deal, there is a slight delay to take the picture after i click shutter button. It is similar to the shutter lag on stock camera but somehow a little bit different. Even if i lower the amount of hdr enchanced frames to 7 from 15, it helps a little but not that much. My solution is, whenever i want to take a picture of a moving object like a dog or child, i go hdr+ instead of hdr+ enhanced. If you have ideal lighting conditions or if you don't care about blown out highlights, for these cases, not using hdr+ enhanced is the way to go.

Have uploaded the new version:

I like this new v52 version a lot. Well done! I have attached some pictures taken in different light scenarios and lens modes.

    i installed LMC8.4_R17_Scan3D.apk and LMC_17_v13 config. but photosphere not working. i need photosphere. how to make it work ?
    Hey mate,

    you need to use LMC_17 v6 config, turn on ID5 Camera in "Additional camera" settings, and than - follow this instruction:
    How to use 3D panorama (vel sphere mode):
    1. Activate 3D camera on right side, after the app will be crushed
    2. Long tap on GCam icon to choose "Make a selfie"
    3. Switch from selfie directly to 3D panorama MODE (not a camera module).

    Have uploaded v12:
    LDR it's so good on many scenes like this :)

    Have uploaded the new version and updated the post description:
    Have uploaded the new version:
    I see more detail with the stock software to be honest. Example: the New south Wales is easier to make out on the license plate on the vehicle in front of the Bimmer.
    The BMW logo on the center cap is also clearer with stock software.
    I believe the New south Wales font you've mentioned is because that its actually out of focus in the raw file since the aperture is really big on main lens, that gcam didnt know how to properly sharpen it since its not optimize for this camera at all.
    But if you look the in focus area, stock camera was lack of detail and kinda look like painting, include the center cap you mentioned. Many source said that samsung didnt use the method that iphone 14 pro used which is cropping the 48MP main sensor to capture 2X photos, that allows the phone to use a whole 12MP to capture the scene.
    I assume that samsung just using the 1X 12MP photo and crop it to 2X(so the photo only has 6MP) and then upscale to 12MP again using AI or some algorithm, thus why the poor quality.
    I'm looking these on a pc with a monitor, here are some 100% zoom for compare.

    Rims been deformed and lack of detail on center cap, fake detail on tires.

    tons of noise cause by the sharpening algorithm
    螢幕擷取畫面 2023-05-15 144200.png

    lack of detail on badges, plate and background

    rear bumper been deformed, lack of detail on ground.

    New post about my new configs for LMC R16+ for s23

    -v1 only for ultra:

    Have uploaded the new version:
    Some sample from my recent trip.

    Probably is not the best photo quality on the market, but using the Gcam overall I'm very satisfied of the incredibile versatility.
    Plus the device is all around the best you can find.

    I did many test gcam 12mpx vs stock 50mpx and 200mpx, and i can say that most of the time high res stock is useless. Details are similar or even better with gcam at 12mpx.
