Ok since I lost hope on seeing a Gcam Mod that could use the full 50MP or 200MP from main camera, I thought of something new ;)

If we could somehow automate the process of taking a picture with Samsung camera at 50MP or 200MP (maybe RAW) then quickly take "the same" picture with a Gcam Mod and then merge both with a new image processing app that could take details from high MP picture and colours from GCam to generate a 50 or 200MP final picture (DNG or HIEC) it could be something better than both cameras in all situations.. off course it could take 2 or 3 seconds to take both pictures but in some situations it would be worth it... The merge process could be done later on (plugged to a charger) to save resources (battery) and time (or even on the computer but ideally following an automated process for not needing user intervention for every picture taken). Any ideas?

PS: actually I have thought of something similar long time ago to take a picture with a Tele lens camera and at the same time same picture with a wide lens camera and then merge both keeping a much higher detailed image in the center. But with the advances in AI sooner or later we will be able to do this and more (apply detailed texture from center to peripheral image) or use the 3 cameras to improve even more on details giving a real detailed center image with semi-AI image around and have a very high megapixel count (BTW Google already generate new content to extend image with AI, so if it had a lower resolution reference of what should be there, it should be able to create a closer to real image outer part).

When saving image we could make use of a variable lossy image compression algorithm that would have high bit rate in the center and more compression in peripheral parts of the image.. (that simulates our own eye retina resolution distribution, and with the background blur trend it wouldn't make much difference to image quality but file size would be small) but I think that is something for a Google, Samsung, Apple or (some new AI photography oriented company) to implement as a groundbreaking new trick on mobile photography, just leaving the ideia here ;).

Not having full resolution in GCAM is a limitation of API, not GCAM itself. So until Samsung decides that 3rd party apps can use it, we will have only 12 Mpix.

Except for very good light conditions, both 50 and 200 are bad IMHO and not worth trying. In full sun yes, you can see some more details there, but ...

I assume that picture processing happens on rather raw output from the camera. What Samsung gives you in higher resolution is only heavily processed files, so further processing it with any algorithms can only damage it more. If we have access to the raw stream of data from the sensor in higher resolution, to merge pictures, then it would be used in GCAM with no need to merge images from the Samsung app.

As for merging pictures from the tele and main sensor - I believe Samsung is doing that on some zoom levels, but I don't remember the exact numbers.
[Samsung Galaxy S23 Ultra] mikexilva:
Ok, Samsung might not have it in camera API but their stock camera app can output a DNG (RAW) file with 50MP size that shows a considerable more detailed image with good light. Maybe that image is already some result from processing but it's definitely using more resolution.
[Samsung Galaxy S23 Ultra] ajarosz:
DNGs from Samsung apps are not RAWs. They are pre-processed. True linear raws are possible only with GCAM. There was a topic related to that somewhere on this forum.

But yes, even though they are pre-processed maybe, just maybe it is theoretically possible but that process would be not that easy. Samsung gives you 50Mpix DNG, but as a result of app processing, not through the API. So you need to have the app opened. And then, you need to open GCAM to take another shot. And then combine. Between shots, framing can change,etc.

With what I see from Samsung files, I would say it is not worth it. When I was in Italy I took about 1k photos with GCAM (JPG +DNG, as always on vacations). Every day I took some ExpertRAW/ Samsung Stock PRO photos in 50 Mpix, just for comparison. And did not find a single instance, when I preferred any of Samsung ones over DNG from GCAM. PRO is very noisy and somehow has limited DR. And ExpertRAW is just a processed mess, which I cannot stand.

Of course, it would be nice to have a bit more resolution to play with, like 16-20, it is what it is.
[Samsung Galaxy S23 Ultra] Baker35:
So the DNG file in each Gcam are raw ? I mean LMC or Agc ? Because the DNG file in the LMC colors like Tint color is set in the middle, which is the same as in the expert raw application , in Agc is shifted Tint color to the right to the very end , then is left only to adjust the white balance .
[Samsung Galaxy S23 Ultra] ajarosz:
Well, GCAM has to be compatible with many devices, and therefore able to read RAW from all of them. If some configuration is not correct, then we can have such results. It does not mean that it is not raw data. RAW is not completely not-touch data from the sensor. It has to be a little bit prepared for further adjustments.

I do not know AGC, as I do not use it. I use LMC and if works there. I remember there was an issue with that, and you could change I think HDR model to fix that. Configs are rather optimized for JPG, so sometimes there is something with writing RAWs messed up, as most of people do not use that at all.

But for how to fix that green tint in AGC, probably people like JavaSabr or Maxazarov19 are better at answering that. :)
[Samsung Galaxy S23 Ultra] andreasarxon:
Hello everybody, after thousands of testing photos over the previous year I have settled to 8.4 lmc r18 with my xml. This xml is most for human subjects( i use it for my kids) . It has pleasant colours, natural detail and fast shutter day and night. The night photos is true to life and not overexposed. Feel free to use it and i am waiting for feedback
[Samsung Galaxy S23 Ultra] Baker35:
I tested it and it looks nice, but I feel that there are more details in Agc java or mazar, but here the dng file looks much better, does hdr work properly?
[Samsung Galaxy S23 Ultra] vkmaxx:
Sphere mode is not working in AGC 9.x :( There is only black screen.
[Samsung Galaxy S23 Ultra] Davids777:
Thanks for updates. I don't come here from a long time and want to update my GCam app with your excellent settings... I just want to know if they work with 9.2 too or only with 9.1 ? Thanks
[Samsung Galaxy S23 Ultra] Baker35:
in lmc dng works fine, what version are you using and what xtml file?
[Samsung Galaxy S23 Ultra] ajarosz:
And that is why I use LMC. As JPGs are good enough, maybe AGC has some edge here and there but DNGs work fine. V13 from JavaSabrs with some very small tweaks.
[Samsung Galaxy S23 Ultra] Steerpike58:
I'm currently using AGC 9.1v13 V40 from JavaSaBr. The default filename (with sharp profile) for images is Java40srp_(date)_(time).jpg. Having the Java40srp_ prefix is messing up my whole image storage / sorting process, as I typically rely on the filename starting with (date)_(time). I've just gone through and used a utility on my laptop, to rename all the files to (date)_(time)_Java40srp.jpg but that means now the phone names are different from my laptop storage names, which leads to other issues.

Is there any way to control how the app applies the 'java40srp' prefix? I'm glad it's there to differentiate the files, I just wish it was a suffix not a prefix!
[Samsung Galaxy S23 Ultra] Smatas:
Photo settings>more settings>advanced> delete: photo(or video) prefix name>write your desired suffix in: file name suffix

THANK YOU!!!!! I searched pretty hard for this but didn't find it. This is most helpful!
[Samsung Galaxy S23 Ultra] DexterHimz:
I'm getting colour banding while clicking any kind of picture while using GCam .

I don't have much experience with using GCam.

Please help.
[Samsung Galaxy S23 Ultra] Steerpike58:
That's a really challenging scene to begin with (very dramatic lighting) and is hard to see any problem. Can you just take a picture of a boring green field / gray sky or similar, where the 'banding' might be more obvious?
[Samsung Galaxy S23 Ultra] jungleboy123:
GCam better than Motioncam / stock app? I'm new to S23 Ultra. Thanks.
[Samsung Galaxy S23 Ultra] Steerpike58:
On closer inspection, moving 'javav40srp' from the prefix section to the suffix section resulted in a filename like

(date)_(time).javav40srp.jpg - a 'dot' is added to the suffix (so - (date)_(time) (dot) javav40srp (dot) jpg). This isn't the end of the world for me, I can handle the extra dot; it does seem a little inconsistent, though. Any reason the 'dot' is added to a suffix, but not a prefix?
[Samsung Galaxy S23 Ultra] Smatas:
I don't know. I rename file name acc to exif data (date, time) , this way additional dot is gone..
[Samsung Galaxy S23 Ultra] Steerpike58:
Do you rename on the phone, or after copying to a computer?

[Samsung Galaxy S23 Ultra] Baker35:
Lmc r17 java v13 is better in my opinion anyway, so why? because there the dng file is better, in agc dng files are useless, they have a green tint, agc is only faster than lmc and that's it, in my opinion someone should make a dng file in agc so that it can be processed normally.
[Samsung Galaxy S23 Ultra] JavaSabr:
I have better output from my AGC config than my LMC config...
[Samsung Galaxy S23 Ultra] ajarosz:
I think he talks about DNGs only. I use both AGC and LMC with your configs and I am happy with both. When I know that I will not play with the output, I use AGC. But when I need DNG I go for LMC, as I had a few situations, where the tint slider was maxed out in DNG from AGC, and I felt like I needed a bit more. You can work with curves to compensate for it, but I prefer the correct WB workflow in my DNGs.
[Samsung Galaxy S23 Ultra] JavaSabr:
Everyone can find my updates for s23 configs on AGC toolkit portal.
[Samsung Galaxy S23 Ultra] JavaSabr:
I have already provided RAW version of my config with focus on DNG files.
[Samsung Galaxy S23 Ultra] ajarosz:
And that is so freaking easy to use. I recommend AGC toolkit for everyone with AGC installed.
[Samsung Galaxy S23 Ultra] ajarosz:
Missed that one!
[Samsung Galaxy S23 Ultra] Baker35:
this is about dng, the dng file from lmc is a raw file and the jpg file is without noise, the file in agc dng java raw is configured, but the jpg is with noise

yes, I used your dng configuration under agc, but it has a lot of noise compared to lmc
[Samsung Galaxy S23 Ultra] JavaSabr:
a lot of noise in raw?
[Samsung Galaxy S23 Ultra] Baker35:
I have DNG turned on all the time in LMC, because I never know whether I will use it for processing or not, if JPG is enough for me, I expect the same from AGC, but the DNG profile has noise in JPG files and it is a bit weak.
[Samsung Galaxy S23 Ultra] JavaSabr:
because my jpeg output on AGC is optimized for another DNG version (which you have in soft/sharp/etc), and if I want to merge raw version config with my usual I need to rework jpeg output
[Samsung Galaxy S23 Ultra] Baker35:
It would be nice if it could be done because I don't want to change the configuration all the time because after each change I enter my settings and it takes too long and then I prefer to use LMC because I don't have to change anything.
[Samsung Galaxy S23 Ultra] JavaSabr:
I don't see any reason to work with raw on gcam :)
[Samsung Galaxy S23 Ultra] ajarosz:
I like the outputs of the GCAM, but it is not always perfect and sometimes e.g. from my vacations I prefer processing in some mood type, like here from Jordan: I went with a much warmer look because for me it was better suited for the given place. But I figured it out after I was back from the trip. That's why I prefer to have JPG and DNG at the same time.
[Samsung Galaxy S23 Ultra] JavaSabr:
The jpeg is enough for such editing
[Samsung Galaxy S23 Ultra] Baker35:
I also prefer to have dng and jpg at the same time, jpg should not be processed because they fall apart and sometimes you need to correct it more, but I have the impression that jpg from agc is better processed than dng, but I think it's because of the green color of the dng
[Samsung Galaxy S23 Ultra] ajarosz:
No, it is not. Well, of course, you can do some editing, but shifting colors on the JPG that much causes color banding. Maybe it is just me, and I am used to it, as I'm used to taking like 40-50k pictures a year and processing them quite quickly, but I always prefer to have raw files always if I can.

Just to check it, I have found the first one on my phone, applied some simple processing to make it look similar and we can see, that it starts to fall apart because of the overblown sky:

I am not saying that it is the case for everyone, and most of people can be perfectly fine with only JPG, which is super nice, and you did a great job there. But for me, DNG is a bit more important that JPG, and in perfect world I would like to have them both. So for now, I probably stay with my drill - LMC for most of the cases, as I can send some quick nice snaps from there, and later process files in the way I like.
[Samsung Galaxy S23 Ultra] Baker35:
I think the same and have the same feelings
[Samsung Galaxy S23 Ultra] Baker35:
if Java claims that Agc and its configuration is better than LMC java v13, let it tell you what it is better in? or maybe two photos of the same frame for comparison.
[Samsung Galaxy S23 Ultra] JavaSabr:
the issue with sky is more related to using correct profile than to work with RAW :)
[Samsung Galaxy S23 Ultra] ajarosz:
It was LMC on HDR+ with 30 frames. I think I could not get more HDR out of it. The point is you always lose something when processing photos in JPGs.
[Samsung Galaxy S23 Ultra] JavaSabr:
my LMC config doesn't support HDR at all, I started supporting it only in AGC
[Samsung Galaxy S23 Ultra] ajarosz:
Are you sure?

Two shots from now from LMC, one has HDr in the middle setting, the other on the last. When I was checking it, there is a difference in the quality and HDR when changing a number of frames for the last one.

I do not mean to argue with you. I am just saying that I see a noticeable difference when processing DNG and JPGs and that is me. You can be ok with just JPG, and that is fine too.
[Samsung Galaxy S23 Ultra] JavaSabr:
It's still not true HDR which we have in AGC, it's just underexposed frames with shadows boosting... in AGC with HDR profiles we have true bracketing...
[Samsung Galaxy S23 Ultra] ajarosz:
MaxHDR from last config for comparison.
[Samsung Galaxy S23 Ultra] JavaSabr:
is it zsl? in AGC need to use night sight for max dynamic range
[Samsung Galaxy S23 Ultra] ajarosz:
My bad, it was not. Now it is:
[Samsung Galaxy S23 Ultra] Baker35:
I take HDR photos in night mode in LMC and it comes out very well, even the same as in AGC, I will also add that in LMC there is a focus point in night mode and in AGC the focus in night mode is only in the center.
[Samsung Galaxy S23 Ultra] JavaSabr:
LMC has a similar output as my LDR profile in AGC and it has a much less HDR level than HDR profile in AGC
[Samsung Galaxy S23 Ultra] Baker35:
In general, I don't see any difference between Agc 9.1 java and LMC, I also tested 9.2 Mazar, but I don't know why there are so many options to choose from, which work poorly anyway, so the only difference I see is that Agc has a dng file like in expert raw, i.e. pre-processing and then it is no longer suitable. I'm waiting for a visual demonstration of the differences between LMC and Agc because I've been testing AGC and LMC with different configurations for a long time and I don't see any major changes.
[Samsung Galaxy S23 Ultra] JavaSabr:
I see a lot of differences between profiles... so I don't understand why you don't see it :) LMC has no profiles so Idk how you can compare it at all :)
[Samsung Galaxy S23 Ultra] Baker35:
so we are waiting for you to show how big the differences are compared to lmc
[Samsung Galaxy S23 Ultra] ajarosz:
From what I took some snaps AGC has better details, and I don't deny it. However, the difference is not as big as between the Samsung app and GCAM in general. JavaSabr did a great job with both. So I use LMC just to have good JPG and DNG at the same time. If not that issue with tint when using profiles other than RAW in AGC, probably that would be the only GCAM that I use.
[Samsung Galaxy S23 Ultra] JavaSabr:
I don't have LMC now and I'm not going to install it... I talk about the difference between AGC profiles... LMC has only 1 profile which is not universal, it's similar to only profile MaxQ-LDR and that is all. but in AGC we have 6 profiles with different output/performance.
[Samsung Galaxy S23 Ultra] JavaSabr:
in good light condition, I mostly use only balanced* profiles which are much faster than LMC/MaxQ AGC and provide enough quality and better motion because use less frames.

MaxQ* profiles I use only in bad conditions, LMC doesn't have my sport profile (which I often use to capture my dog outdoor) and LMC doesn't have Astro profile.
[Samsung Galaxy S23 Ultra] Baker35:
Lmc vs Agc HDR end detal
[Samsung Galaxy S23 Ultra] Dayuser:
Both pictures looks horrible.
[Samsung Galaxy S23 Ultra] Baker35:
java, is this raw in your configurations real or close to real?
[Samsung Galaxy S23 Ultra] chetszot:
Could you please instruct where to set the HDR range in LMC?

I was playing with my LMC settings (based on great @JavaSabr v13 config - THANK YOU!), but during the whole time I have been using this LMC (over a year from now :o), the only one thing that has always been missing from me is stock-like HDR power.
[Samsung Galaxy S23 Ultra] kaicooper87:
hi guys, i used to have Pocofone F1 since 2019 and been soo happy with Gcam mod

for photography and everything..

i just got my new Samsung S23 (base model) and i need to get Gcam mod but im totally lost here

when i try to follow the instruction from JavaSabr , so i donno which version should i download first

from GCam hub, could u guys help me
[Samsung Galaxy S23 Ultra] ajarosz:
If you talk about GCAM apk, it is just a matter of which app this GCAM will replace (GCAM will use that app signature, and you will not be able to install it next to GCAM). Go for e.g. awesome. Then download the most recent config, place it where JavaSabr describes, give GCAM access to the files, load config from GCAM, and enjoy the best possible quality of pictures from your mobile.

I was using a few GCAMs on a few phones, but I must admit that JavaSabr is doing the best job I have seen on any.
[Samsung Galaxy S23 Ultra] kaicooper87:
i'll follow up with the steps but the only thing im worried now is here, which one?

my phone is just fresh and i have no other mods or gcams before in my Samsung S23 base

so lets say i wanna replace the base cam with Gcam (and yea i'll go for Java config for sure)
[Samsung Galaxy S23 Ultra] ajarosz:
Any. They are exact same app. The rule is: if you get ruler, you will not be able to install original ruler app.
[Samsung Galaxy S23 Ultra] kaicooper87:
so i've just downloaded and configured it with Javas, looks awesome

but should i change any settings too or all set already?
[Samsung Galaxy S23 Ultra] Maxazarov19:
Dear friends, I edited the post and now provided links to download configs from the AGC Toolkit platform (an application created by the AGC developer himself). I provided the download link in the post. Thanks everyone and good luck with your photos!

i've installed Javas settings, it was working so smooth and awesome quality

also when i press to take a shot, it taks to 1 second to shot it

but now suddenly all the new shots are blurry !!! what happened?
[Samsung Galaxy S23 Ultra] Steerpike58:
Help! I just took some great shots with AGC91v13 v40 with both MaxQ-HDR and Balanced-HDR profiles, but noticed they were both 8160x6120 (50 MP mode). I then took a 'night' version, same resolution. I've been taking hundreds of shots through yesterday and they are all basically 4080x (12 MP). I have no idea what I did to get into 50 MP mode.

This is S23+, 1x lens.

I just changed lenses from 1x to 3x to 0.6x and back to 1x, and now, sizes are back to normal. What did I touch/press/do to get the 50MP setting? I may want it in the future - but need to know how to control it!
[Samsung Galaxy S23 Ultra] chetszot:
As far as I know, Samsung has blocked 50 Mpx mode for 3rd party apps.

I am very interested how did you manage to get that 50 Mpx.
[Samsung Galaxy S23 Ultra] Steerpike58:
I can't explain it! I have NEVER intentionally used 50 MP mode with the stock app, and didn't even recognize that 8160x... was the result of 50 MP setting at first! I tend to use the stock app for most mundane daily shots b/c it's quicker (and for the 0.6 lens, applies the much needed distortion-correction), but use GCAM when it's an important picture. Yesterday I used the stock camera to take a video of some birds outside my home, then used GCAM to take the picture in question.

I'd just been reading one of java's posts about using 'balanced-HDR' for most shots, and 'maxQ-HDR' for 'difficult' shots. So I went to the profile settings, and chose balanced-HDR, then took picture 1. I then went back and chose MaxQ-HDR, and took picture 2. I then selected 'Night Sight' and took picture 3. I then looked at all three images, and compared file size (hoping to learn about how much detail was in each variant) and was shocked to see 25 MB or so assigned to each file (and all three had very similar file sizes, not to mention identical appearance).

This panicked me a bit, as I don't want to be eating up 25 MB per picture, so I looked at all the settings I could find, and nothing was obvious. So then I cycled from 1x to 0.6x to 3x and back to 1x, taking a picture with each setting. Then I noticed everything was back to normal - I was getting 12 MP images again.

I was asking how to prevent it, but clearly I should NOT have ever seen this!

Here's proof: here's details from two photos, same subject, same GCAM settings, one today and one two days ago when I first saw the problem. Problem has not recurred.
[Samsung Galaxy S23 Ultra] ajarosz:
If that photo is not private, can you please share it here? My only explanation for that is there is a magic shortcut in the GCAM to enable 2x image enlarging. Because if 50 Mpix is not enabled in the API, it should not be possible. Of course, there is possibility that there is a bug on Samsung side, in low level code, where API return wrong data in some very specific cases.
[Samsung Galaxy S23 Ultra] Steerpike58:
I can upload it. What's the best way, considering it's a 25 MB file? I can resample it of course but any 'processing' runs the risk of losing metadata perhaps? I would typically resample it in IrfanView. Is embedding it in a post the best way?

Update - It looks like the site let me upload the full size image, so here it is. I did remove GPS data from it, but I did a before/after comparison and nothing else got touched.
