I just tried changing the shutter priority to 1/7s from auto in low light and while it reduced the noise somewhat the photo was not as focused or sharp so not worth the trade off. I'd rather have some noise and have the photo in focus.
[Samsung Galaxy S23 Ultra] typos1:
I already said that it shouldn't work but it does - try it, then comment.
[Samsung Galaxy S23 Ultra] woffu22:
Hi. Your fence is better now 🙂. But normally I don't like the sky by stock, it's like BonBon Colours. Here the sky now seems to be more realistic by stock ?
[Samsung Galaxy S23 Ultra] woffu22:
Hi, I tried with upscaling 2.0. Now it's 12 instead of 4 MB. But I don't think pic is better, see crop. Only more noise.
[Samsung Galaxy S23 Ultra] typos1:
I use AGC not lmc, AGC has many more upscale options and it works better . But I think the silver thing has more definition in the upscaled pic, although the leaf looks a little more noisy.

I have multiple examples which I'll post later, it does not always work due to the ridiculous inconsistentcy of the s23u cameras (using stock or gcam), but it works more times than it doesn't.

As for file size I really don't get people complaining about it in this day and age when storage is very cheap, 4mb, 12mb both are small size files. What I have also done is take pics upscaled to 180mp in gcam and then remastered them in gallery which results in 16mp pictures with most of the extra detail preserved and smaller files sizes.
[Samsung Galaxy S23 Ultra] woffu22:
No difference.
[Samsung Galaxy S23 Ultra] ajarosz:
I would say that the second one is a bit more detailed. Not by far, not in every place, but there are some differences.
[Samsung Galaxy S23 Ultra] typos1:
Indeed the upscaled one is clearly clearer. But as I said it works much better with agc, mostly, there are times that it doesn't, I also have examples of massive noise and blurry images from agc and no noise from stock. But that's cos we're still doing the development of the s23u's camera for samsung. Having paid it $/€/£1400 for the privilege 🙄
[Samsung Galaxy S23 Ultra] woffu22:
Yes, it's a sort of Antialiasing doing it this way. But not more information, where should it come from ?
[Samsung Galaxy S23 Ultra] ajarosz:
The only way of having more information would be for the algorithm a clever way to use the shift of frames of HDR. If not then probably it is a game of guessing based on some trained data.
[Samsung Galaxy S23 Ultra] woffu22:
If you want a clearer pic the better way is to copy to a PC, take Topaz Denoise and experiment with it, really good results.
[Samsung Galaxy S23 Ultra] typos1:
I had hoped that somehow it was able to access the 50mp and 200mp streams from the camera, but deffo not as it also works on the other lenses too, although not quite as well. It may just be that less information is junked in processing when upscaling compared to when not upscaling.

But whatever it works, mostly.
[Samsung Galaxy S23 Ultra] typos1:
And how is that going to get extra information from an original without it ?
[Samsung Galaxy S23 Ultra] woffu22:
😅 nothing, but Antialiasing, sharpening and Denoise in perfection
[Samsung Galaxy S23 Ultra] seattlesbest02:
Wow. Thanks for this!
[Samsung Galaxy S23 Ultra] Ten306:
Has anyone tried the photosphere feature? Can you show an example? Do the panorama and astrophotography functions work? Those of GCAM are much superior compared to Samsung's camera.
[Samsung Galaxy S23 Ultra] penfold:
i tried playing around with shutter priority setting again today and i see that setting both exposure threshold and shutter priority to 1/3s results in more detailed images, so good call ( although wether it decrease noise or not I can't say, there may actually be more noise to you with the extra detail)

shutter priority on auto first pic, shutter priority at 1/3s second pic
[Samsung Galaxy S23 Ultra] penfold:
i also see that changing the shutter priority also signifigantly increases capture time for hdr++ in low light, meaning you have to hold the cam still for longer

....will have to play with options to find a good balance
[Samsung Galaxy S23 Ultra] typos1:
If you want decent low light pictures its worth the few seconds needed for longer shutter times.
[Samsung Galaxy S23 Ultra] penfold:
i've gone back to 1/3s threshold and auto shutter priority .....tried setting shutter priority to higher iso, was great for standard photos but too much grain for hdr++ in low light

best compromise is auto shutter priority although some detail lost
[Samsung Galaxy S23 Ultra] typos1:
The AGC version that works on the s23u is rubbish for night mode, but last night in a dimly lit room I adjusted the iso and shutter speed manually and got significantly better results.

Having to do it yourself kinda defeats the whole gcam night mode thing tho, I mean night mode is one of the things it was originally known for.

Can find anything in settings to adjust night mode, although I didnt delve far.

Still at least the flash works with the main lens with @GroovyGeek's latest config - the last one the flash fired but the shutter must have gone off before or after because the pictures looked like there was no flash.

Still happens with the zoom lenses tho, not tried the wide angle.
[Samsung Galaxy S23 Ultra] borijess:
While do all these Gcam apk force close on me. What am I doing wrong?
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
It's an AI-based tool. It analyzes the photo you took and reads thousands if not hundreds of thousands of other photos from the database so it basically applies the "corrections" where needed. Your photo looks the same, but denoised and with a minimal loss of details. Doesn't work great with people photos, but with everything else is great.

So, it doesn't really create something that it's not there, it just removes the noise with minimal impact on the actual textures, details, and everything in the photo.

They have other tools too, like for sharpening which is also great, and even upscale, for both photos and videos.

"Expensive" tools if you don't use them regularly or if you're struggling with money. lol

Otherwise, IMO, it's worth the money. It saved a bunch of my either out-of-focus photos or motion blur ones.

Denoise is great too, use it on my RAW photos from D750 often.
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
You're probably not reading the instructions.
[Samsung Galaxy S23 Ultra] typos1:
I havent uploaded a photo (yet, but I do need to to show the results we are discussing), but the photo you are referring to has been upscaled in processing by AGC gcam.

The results are better than without upscalling, as you can see.

I think youre conflating two different posts from two different people and have therefore got totally the wrong end of the stick, suggest you re-read the posts more carefully. :)
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
No, I'm aware of the context and the conversation between your and his posts.

And he mentioned Topaz Denoise.

And my explanation also targets upscaling since Topaz Labs also has an AI upscale that uses basically the same methodology to upscale and preserve details.

So, this targets upscaling and answers your question regarding the "lack of information without the original photos".

More as an "addition" to his reply.
[Samsung Galaxy S23 Ultra] typos1:
I always assumed that the person youre referring to was a lady because of their profile picture, but you cant be fully aware of the context because I did not upload a picture and you seemed to think that I did :)

As good as Topaz may or may not be it likely cant do as well as upscalling via AGC as you are taking the actual picture, as its the results from that that it would have to work with.

And the extra information would be artificial rather than reality. In which case we could sell our very expensive s23u with their underdeveloped cameras, buy 10 year old Galaxy s2s and then let Topaz AI magic up fake information to fill in the gaps between its 8mp camera and the very poor 12mp results we see from the s23u.

TBH that might well work better than using the s23u at its current stage of development :ROFLMAO:
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
I don't need to actually see YOUR example photo to understand how upscaling on these specific Gcam ports work and to understand the whole context. I can read fine and comprehend what the replies meant just fine. lol

And Topaz does far better compared to what upscaling in AGC Gcam does. AGC doesn't use AI to do upscaling.

Why would be important if it's "fake" data that is inserted if the photos look the same? It's not creating beauty out of a beast. And using S2 as an example is just hilarious because it's not only about the resolution, but the actual sensor size and how much light can enter through each pixel, as well as how is the sensor handling the noise, colors, dynamic range, and many other things.

Topaz isn't a magic wand that just fakes your photos, but yeah, you would actually need to try it out to actually see what it does.
[Samsung Galaxy S23 Ultra] GroovyGeek:
This happens in both day and night mode when there is a low dynamic range within an image. Enable HDR++ and see your problems (mostly) go away but you need steadier hands. Improving night performance is why I had jacked up the shadow compensation to where it was in V6 but that messed with daytime pics. I may add a "night" settings under config2 but I need to test it. Alas I don't have enough time to test what is needed.
[Samsung Galaxy S23 Ultra] typos1:
You're still not paying attention - for the second time I have not uploaded any photos.

And we we're talking about getting gcam to upscale it's output, not moving the files to an entirely different and much larger device, going into another app (the developer of which I assume you know, work for, or are by the way you keep promoting it 😂) and doing it all yourself. I mean we could also maybe hire the local super computer and get that to upscale our images but it's not really the point or relevant here.

The Galaxy s2 example was purposed to be hilarious.😀
[Samsung Galaxy S23 Ultra] typos1:
First thing I do when I install gcam or load a new config is turn HDR++ on (I rarely turn it off) and v6 could not ever successfully use the flash in a room lit only by a tv and a small ambient lamp yet v7 can.

Adjusting the iso had no affect in v6 and it still doesn't in v7 it's only the flash that works properly on the main lens.

Grid lines cant be turned of now btw.
[Samsung Galaxy S23 Ultra] GroovyGeek:
Aah, this has to do with flash. Yes, both my AGC config as well as Javasbr's LMC suck at flash in comparison to stock. Not sure what parameters to tune to adjust flash. I never ever use onboard flash, whether on a cell phone or dSLR because it results in such harsh shadows and contrasts that it is not worth the effort.

Grid lines work for me just fine. Not sure why you are not seeing them.
[Samsung Galaxy S23 Ultra] penfold:
flash on lmc is only ok at close range, is not bright enough to light up a larger area.

from my evening stroll
[Samsung Galaxy S23 Ultra] Timtaylor22:
Thank you for your help,

I can find Sharp Mini and Sharp Macro, I don't find Sharp Edge. Where can I find Sharp Edge?
[Samsung Galaxy S23 Ultra] GroovyGeek:
Which version of AGC is this? Does not appear to be v9.5fix because on mine it says "Sharpening edge" right where it says "Soft sharp" on yours.
[Samsung Galaxy S23 Ultra] Timtaylor22:
I just see that I took the AGC version 8.7.250_V4.0_SCAN3D, but actually works very well with your gg_agc_v7.agc. Here are some examples.

Thanks again for your effort.
[Samsung Galaxy S23 Ultra] borijess:
Thanks!
[Samsung Galaxy S23 Ultra] Timtaylor22:
@GroovyGeek

I once made a comparison between the AGC 8.7.250_V4.0_SCAN3D and the AGC 8.4.300.9.5fix, both with the GG_agc_v7.agc and activated HDR+ and the 10x lens. With strong enlargement you can see that the 8.7.250_v4.0_scan3d are less rustling or artifacts are interesting.
[Samsung Galaxy S23 Ultra] woffu22:
Don t have this artifacts with 8.4 v9.5 GGv7, but had the same with previous version of AGC, there was something wrong with config. (10x HDR+)
[Samsung Galaxy S23 Ultra] GroovyGeek:
Hmm I have tried 8.7 v4 a number of times and it has always crashed for me, certain critical options just could not be enabled. However I used the aweme package so as to have it running side by side with 8.4 v9. 5fix so perhaps this is the issue. I will need to re-download scan3d and retry.

As to artifacts, these are very difficult to troubleshoot because they show up selectively. They seem to be driven by a combination of the choices for lens logic and HDR model. At one point I thought that I can correct for them in areas of high detail which is how I ended up with HDR model auto and lens logic rear telephoto for all but the wide lens. This did a great job on very fine detail for all lenses and I also "stole" some of Javasabr's sharpening settings to tone down AGC's tendency to over sharpen. Apparently I have more work to do.

Can you post some details about the exact config that triggered the artifacts so I can attempt to reproduces

1) gcam version - 8.4 v9. 5fix?

2) lens - 10x?

3) zoom level?

4) hdr+ or hdr++

5) Any other options that are not default on the config?
[Samsung Galaxy S23 Ultra] Timtaylor22:
@GroovyGeek

It is the AGC 8.4.300.9.5fix Aweme, HDR+, 10x lens with 10xzoom and AWB is over and no further special settings. I stay on 8.7.250_v4.0_scan3d with your gg_agc_v7.agc I can confirm a crash with the 8.7.250_V4.0_SCAN3D, the 8.7.250_V4.0_SCAN3D does not go a top shot, the cam always falls. Thank you again for your work, if you have Estwas for testing, I would be happy to do that.
[Samsung Galaxy S23 Ultra] penfold:
@GroovyGeek

I just played with your config this morning ....excellent thanks.

If you like though I made some very quick changes for better light balance ....by no means a full job but just on the fly. If you would like to try them out I can send you the settings ...as i said they are by no means fully done, just a quick test.

(not going to post the configs here).

samples, stock, gg, gg with my tweaks
[Samsung Galaxy S23 Ultra] chetszot:
I haven't been following this thread for few days and I truly like to come back here and see how these great configs evolve, but - pardon my directness - I think you are overdoing right now.

Your previous samples I was looking at few pages ago were a lot better. These are very similar to the stock one. Better indeed, but worse than the ones you have presented few pages ago. I am allergic to oversharpening artifacts that whole S23 series do and kills all photos and these samples are unfortunately oversharpened for my taste. Green grass has too much whitenish tint coming from oversharpening artifacts.
[Samsung Galaxy S23 Ultra] penfold:
who exactly are you talking to?

you quoted my post quoting GG ...is it me or him?

Your post makes no sense.

Which samples exactly are you referring to that you find oversharpened?

It would be nice if you could explain your posts rather than just posting what's in your head that noone else can understand.
[Samsung Galaxy S23 Ultra] JavaSabr:
Just random samples stock vs gcam:
[Samsung Galaxy S23 Ultra] CarlosLopezES:
I think that what @chetszot means it that when a modder fix the bugs and get a good configuration, it's a good point for almost anyone, but every artists have his own desire of perfection, and it's hard to stop working in improving it.

I agree in some part, once you have a good configuration, week changes are back and forth and a matter of taste, but I think that "stable" configs are possible now, even if every week creators wants to share "beta" configs.
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
And you're not paying attention to the "you don't need to see photos to understand how upscaling on Gcam works".

I'm not promoting anything. The guy mentioned Topaz, I added my two cents regarding Topaz, and that's it.

Enjoy the AGC upscaler. lmao
[Samsung Galaxy S23 Ultra] ajarosz:
But the discussion was about whether upscaling in AGC gives any gain in details, and then using Topaz to denoise it on top of that as an addition. Not about using Topaz to upscale. So of course, you can use Topaz Gigapixel but it is rather how to set AGC to give the best possible results.
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
I understand that. As I said, it was just an addition to the other person already mentioning Topaz. Not trying to switch the topic to Topaz at all.
[Samsung Galaxy S23 Ultra] GroovyGeek:
I think he was referring to your previous configs on LMC and that he prefers them. You have been a lot more active than me lately with multiple comparison postings.

It should be clear that I am responsible for whatever deficiencies exist in the GG_AGC_v7 config. tmzbeme is providing useful feedback that I find helpful

At this point there are multiple camps and no one config can make everyone happy. For people who are not happy with what is on offer there is only one choice - DYI.
[Samsung Galaxy S23 Ultra] woffu22:
I think you were talking about the AGC config from GroovyGeek that was changed a little bit from tmzbeme. It is right, the AGC is going more in direction to stock with a bit oversharpening etc. But for me it's not bad, the attempt of improvement looks very nice and everyone enjoys another taste, it is the advantage of gcam.

Generally here we see a lot of nice and good pics of Landscape, not many pics of People or portraits, where you would prefer a shorter exposure time and no HDR ++, and for this case it's no failure to compare different versions of gcam, because none of them seem to be perfect for every situation.
[Samsung Galaxy S23 Ultra] penfold:
well i can't help people getting upset about trying to make improvements ....if they are not happy anyone is welcome to do it themselves.

regarding the GG pics, here are some test shots.

stock, GGv7, and GG with some light correction to make it look exactly as it looks in reality. I'm just posting what i see and i only adjusted the light, didn't play with sharpness or anything else. To me the GG shots are way too dark outdoors, the corrections also help for indoor shots too.

I'm happy to share the settings with groovy so he can make improvement as he sees fit or can leave as is if happy with it, just trying to help.
[Samsung Galaxy S23 Ultra] woffu22:
Thank you, very interesting. Inside the GGv7 is good, and you are right, outside and especial against light it is often too dark, so your improvement is very helpful. Would be interested in the config.
[Samsung Galaxy S23 Ultra] GroovyGeek:
Thank you for confirming the crash on 8.7. I downloaded the ruler version today and it crashed the second I loaded my profile, so I was wondering what I am missing. I may take you up on your offer to test drive. Let me try to identify the cause of the aberrations you noted.
[Samsung Galaxy S23 Ultra] GroovyGeek:
Don't have problem with anyone who wants to improve things and/or is willing to commit their time to help. I agree that AGC tends to produce somewhat dark images which is why I had jacked up the shadow compensation to +5 in v6, but brought it down to +2 in v7. Feel free to post your config here for others to use as they wish, or DM it to me and I will probably adopt most/all of your suggestions. I am completely new to GCAM and am still struggling to understand the bazillion of undocumented parameters.
[Samsung Galaxy S23 Ultra] maex-la:
Is there a working config for AGC on S23 (not Ultra)?
[Samsung Galaxy S23 Ultra] typos1:
I rarely use the flash in the 6 years I've been using gcam because of night mode but because gcam night mode is so useless on the s23u I thought I'd try the flash. And actually I mentioned earlier that it worked on v7 but I was wrong - it was a very slightly darker and smaller room I tried it in and it worked but the flash still won't fire in the darkened room I was trying v6 on. And the manual shutter control and iso do not work at all so the only option on this phone for decent low light is the stock app so far at least.

The grid lines are on permanently for me whether they are enabled or not they always show.

Fewer artifacts but more blur sadly

No one has mentioned how upscaling works so far just that it seems to give more detail (even though it should theoretically produce more blur).

Your constant referring to "my uploaded photo" even though I have not uploaded one and your consistent failure to even address me pointing it out does not inspire me to think that you are keeping abreast of everything being discussed here.

As does your total inability to get my tongue in cheek comments in order to put some light humour into our discussion.

Enjoy your Topaz

Read the thread.

I am on my second s23u, the first I installed both lmc and agc. I was not happy with the colour of the device so sold it and bought one the same spec but a different colour. I installed agc on the second but could not install lmc. So I gave up and just used agc and stock. I want to try lmc again but I cannot use it I have tried multiple versions including r16 but it always crashes even with configs loaded. Admittedly I have not tried all versions yet but I am reminded of that guy a few pages back who could not successfully use any gcam without it crashing. I also had a strange bug on my previous s23u where 2 apps worked for a couple of weeks then crashed every time I opened them. The solution was to install them in the private folder but that shouldn't really be necessary. The same apps have worked fine on the new s23u and have not required me to move them to the private folder. So it seems samsung still has a way to go to properly sort the firmware on this device.
[Samsung Galaxy S23 Ultra] citytrader:
It means you don't shoot people in low light, otherwise the flash is needed ever.
[Samsung Galaxy S23 Ultra] typos1:
Do you mean NOT needed ever ?
[Samsung Galaxy S23 Ultra] maex-la:
I understand that YOUR config is for S23U only. No need to be so harsh.

But I didn't ask you but anybody. Possible that anyone (but you) knows a working config for any version of AGC on S23.
[Samsung Galaxy S23 Ultra] typos1:
I don't care who you asked, you need to read the thread to find out just like everyone else, basic forum rules, the info you require is there for you if you can be bothered to read it, but don't expect others to keep parroting info that is already written because you are too lazy to read.
[Samsung Galaxy S23 Ultra] naseemu622:
Searching the internet, I came across plenty of GCam options. Installing them in my Samsung S23 Ultra, I was able to capture awesome pictures but while switching to the video it was crashing constantly. In some versions, the ultrawide camera was not displaying anything to the screen.

Finally I found this apk which gave me the best results. In this, the video is working, ultrawide camera is also working and app is not crashing.

Videos can still be made with the stock camera. GCam is actually intended exclusively for pictures - the stock has good features in the video function.
[Samsung Galaxy S23 Ultra] woffu22:
Hi, for me it was possible to install 8.7.250v4.0, but after loading GG_acg_v7 or V8 it crashes everytime. How did you manage to work ?
[Samsung Galaxy S23 Ultra] typos1:
No gcam is intended for pictures and video it is a port of google camera from pixel devices. On the s23u so far due to both samsungs poor development of the cameras and the fact that gcam is developed by the community not companies some people think that the stock app is best for video.

I have installed it too but it is not as good as 8.4 sadly. I m trying to remember how I got around the crashing but I cant so far.
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
Videos on Pixel phones look like a meme compared to for example S23U on stock camera.

Gcam was never a better alternative to videos made on the "stock".

Have both Pixel 7 Pro and S23Ultra. S23Ultra outperforms the Pixel 7 Pro in video recording by a mile.

The post-processing on Pixel 7 Pro videos is just horrible. Full of luma/chroma noise and artifacts all over the shadows or dark spots.
