If you tap the lens you're on a 2nd time, notice how it goes from 1x to 1s. This is manual upscale. Not sure if Java configured it, I think by default it's set to 2.0x or something. So you probably tapped it twice than took shot. This is just post processing upscaling. Gcam can't access Samsung's real 50mp mode
[Samsung Galaxy S23 Ultra] olafsand:
Yes. 2 times hit 1x, will be 1s and file is 50MB
[Samsung Galaxy S23 Ultra] Steerpike58:
Awesome, thanks! I would never have spotted that subtle indicator. What's a reasonable use-case for doing this upscaling?

Playing with it now, I see it's persistent across launches of GCAM, so it could have stuck for a long time! Switching lenses does reset it (but I do 90% of my shooting with 1x lens). Thanks again!
[Samsung Galaxy S23 Ultra] BoneXDA:
How do I change naming scheme for every GCam shot taken say from AGC_javav20srp_20240229_142310801.NIGHT.jpg to 20240229_142310.jpg or even 2024-02-29_14-23-10.jog for easier sight of exact time of taking?

TłumaczenieIs it possible to block exposure in agc?
[Samsung Galaxy S23 Ultra] Steerpike58:
I changed the name as follows:

(gear icon, lower left) / 'more settings' / Advanced / Photo prefix name (remove it, so date is first)

(gear icon, lower left) / 'more settings' / Advanced / File name suffix (set to whatever you want)

(gear icon, lower left) / 'more settings' / Advanced / Change date/time formats ... (change as desired)
[Samsung Galaxy S23 Ultra] Steerpike58:
So .... does anyone know of a useful 'use case' for doubling up the resolution on the phone? Surely it doesn't improve image quality, just occupies a whole lot more storage. I accidentally hit the 1x again today, entering into 1s mode (double up mode), and ended up with a ton of humongous images. I'd really like to disable that feature! Any way to do that?
[Samsung Galaxy S23 Ultra] PhilMorin:
No real use. Just go to settings, lens settings and disable manual upscale for each lens. It can still switch between 1x and 1s but will have no impact
[Samsung Galaxy S23 Ultra] Baker35:
Hello, I noticed recently when playing with photos against the sun with a lens, mainly x10 and x3 Agc java41, the maxhdr profile is turned on when the sun is setting, there are artifacts in the photo that look very bad on a larger monitor, these are artifacts that only occur in worse conditions, on lmc 8.4 then I don't appear.
[Samsung Galaxy S23 Ultra] Steerpike58:
I once spent days tracking down 'sensor dust' with my old Digital SLR, only to finally realize it was 'midges' or similar - swarms of very small flies that showed up in certain scenes. Not saying that's your situation, but since no one else has commented ...!
[Samsung Galaxy S23 Ultra] Baker35:
At night I set my phone in the room for a long exposure time and things like this are strange, what irritates me the most is that the HDR photo falls apart.
[Samsung Galaxy S23 Ultra] ajarosz:
I wanted to ask - how is your battery when using gcam? I have checked with lmc and agc and had similar result/issue. I was using my camera quiet a lot - only photos, with one short video, and both today and yesterday i had to charge my S23U three times... Today I left home with 90 % at 9am. At 13 it was already 27%. Recharged to 80% ( had only tested little time) and by 19 I had already 25...
[Samsung Galaxy S23 Ultra] Steerpike58:
Expectations with S23+ and Night Sight.

I realize I have an S23+, and this thread is primarily for S23U users. But there's a lot of commonality / overlap so wondered if others could comment.

Late last night, I held the camera up against the window pointing out to the VERY dark scene outside - just a couple of distant streetlamps, and possibly some moonlight - quite dark to the naked eye. I took a photo using stock camera app (1x lens) and then with AGC 91v13 v40 in 'Night Sight' mode. Both shots took maybe 2-3 seconds to complete - if that.

As you can see, almost nothing was captured by Night Sight - just the moon in the upper left corner, and a faint hint of the streetlight below/right of center. Is Night Sight not intended for this situation? The image on the left is unnaturally bright, which is a problem in its own right ...
[Samsung Galaxy S23 Ultra] PhilMorin:
Gcam won't do slower than 1/3s in auto mode so even if both took 2-3s to run, gcam was only a stack of 1/3s shots which is too fast for the scene. Stay in normal mode and force shutter speed to 1s and you will probably get something much brighter.

Also, depends what the config locks max iso at. If it's low, it might be too low for that scene, even with 1s exposure.
[Samsung Galaxy S23 Ultra] Steerpike58:
So what is the appropriate use of Night Sight? Elsewhere in this thread, Night Sight was recommended as the best way to get HDR functionality during daytime (recommended over the actual HDR settings). So that means Night Sight is being recommended for daytime use, and now you are suggesting Night Sight isn't good for actual Night time use!
[Samsung Galaxy S23 Ultra] PhilMorin:
I'm not saying it's not good for night time use. It will work for a lot of night time pics that have some sort of light. Here it looks like your scene was mostly pitch black. And not seeing any metadata, can't see what profile you used, iso used, etc. NS will work fine with proper iso cap. There's also astro that can help circumvent the 1/3s limit. Also guessing you're using agc 9.x which doesn't support manual shutter with ns but older version actually can force a slower shutter with ns. Hence why I told you to force shutter speed in normal photo mode (which in the backend will use hdr-e)
[Samsung Galaxy S23 Ultra] PhilMorin:
This was taken with a 1s manual shutter (so hdr-e in the backend), straight out of gcam. No lights at all, barely had any moon light. It's actually quite brighter than what my eyes were seeing (it was complete night so I couldn't see much, even if it doesn't show in the pic thanks to the 1s exposure).

And this is a shot using night sight in auto mode where it used 1/10s.

Ns/gcam can definitely work fine at night
[Samsung Galaxy S23 Ultra] Steerpike58:
Thanks for the info.

The NS shot is shown as being f/1.8, 1/10 sec, ISO 4000.

The 'stock' shot is shown as being f/1.8, 1/2 sec, ISO 2000.

But I thought that these values were somewhat less informative (especially shutter speed) with the way these camera apps run today, stacking images. The NS shot shows profile as balanced-HDR, config name =JavaSaBr S23, Frame count = 15. Can I interpret this as the exposure being 15 frames x 1/10 shutter = 1.5 seconds total? I wonder what the stock app is doing to get such a 'bright' result.

I'll do some tests using manual exposure if I can. And yes, I'm using AGC9.1v13 v40.
[Samsung Galaxy S23 Ultra] PhilMorin:
So yes, that's around 1.5s total it took to take the shot but each picture is still 1/10s as far as exposure goes.

I think Java has an astro profile which probably allows to go to 1/3s even with ns in "regular" mode (ie: not switching to actual astro mode). You can see in his balanced profile he locked the speed to 1/10s because clearly if gcam had been allowed, it would have tried to use 1/3s which is its own speed limit when there's no profile override. 1/10s limit is a good limit for most scenes to prevent hand shake blur though.

For sure though, his balanced profile isn't meant for such dark scene. I'd start by using whatever profile is made for night shots.
[Samsung Galaxy S23 Ultra] Steerpike58:
left shot - AGC91v13 v40 sharp, profile = 'astro'. Shot type=NIGHT.

Frame count = 30; shutter 1/3. ISO 8000

right shot - stock samsung app

shutter = 1/2. ISO 2000 (no indication of frame counts, unfortunately).

The specs bear no relation to the result in my mind - the 'stock' has 50% longer shutter (1/2 vs 1/3), but only 25 of the ISO (2000 vs 8000).

Also of interest - the left shot occupies 9.6 MB, while the right shot occupies 3.2 MB. I know this is all related to compression, but there's so little detail in the left shot that I'm surprised it could be so large (typically, I see a correlation between amount of detail in a photo and its compressed size). But that's not the topic of discussion today.
[Samsung Galaxy S23 Ultra] PhilMorin:
Have you tried manual shutter with 1/2s or 1s? I'm not surprised Java's file size is bigger, while dark, there's still a lot of noise that can't be compressed.

As for iso, I'm not sure if Java uses analog or digital iso. If digital, then that 8000 might actually translate into like 2000 analog (I have no idea what the conversion is, but digital is always much higher)
[Samsung Galaxy S23 Ultra] Steerpike58:
I'm embarrassed to say, I don't know how to set manual shutter in AGC! I looked everywhere ... obviously I'm missing something obvious ...
[Samsung Galaxy S23 Ultra] PhilMorin:
And now I just realized that 9.2 has that bug that won't allow to go slower than 1/7s. 9.1 used to have the bug but was fixed. Going to report it.
[Samsung Galaxy S23 Ultra] Steerpike58:
Well that's embarrassing indeed! I totally missed that 'adjustments' control, lower right! So I hit it, and I was able to adjust shutter speed to (eg) 5 seconds as seen in the screenshots below, and even up to 16 seconds. The exif data confirms the shutter speed.

So I now need to wait till nightfall and do some test shots out the window again!

I still don't really understand why the stock camera gets such a good result in (what seems like) 1-2 seconds. But let's see how manual goes tonight. Thanks again for educating me about the manual settings! (I really wish one could get rid of that top row of icons ... HDR, Leica, AW, M, etc). Just keep the one for configs).
[Samsung Galaxy S23 Ultra] PhilMorin:
Yeah I agree, those top buttons are useless for most but there's no option to hide them unfortunately.

Don't go above 1s, for technical reasons, you won't get better results. Usually 1/2s to 1s is the sweet spot.

As for stock, it probably has some tricks up its sleeve as it has access to raw un binned data too, possibly higher iso etc. Usually in extreme low light, stock can actually produce a "decent" shot compared to gcam, when using similar total processing times.

Also, don't try to change iso, it's broken on Samsung.

And.. That expo slider is very useful and remains set between shots so it can be nice when you want a specific effect, you can take multiple shots without having to set the expo slider each time
[Samsung Galaxy S23 Ultra] Steerpike58:
OK, took some manual shutter shots tonight. Here's the comparison:

1s was almost black; 4s became tolerable, exposure wise, but still not as good as the stock camera which reported 1/2 sec, iso 2000. The noise / detail in the GCAM version was much worse also. Here's a crop of the right side to give a better indication of noise and detail:

Left = gcam, right = stock.

All gcam shots are AGC91v13 v40 sharp, profile balanced HDR.

PS - redid the shots using profile MaxQ-LDR, and there was a very slight improvement.
[Samsung Galaxy S23 Ultra] PhilMorin:
Yeah in ridiculously low light, stock can do some magic that gcam can't with the same exposure. Though it's far from perfect too. Looking at big tree in the foreground, it's all mushy from the excessive (necessary?) denoise stock applies. At least gcam somewhat keeps the texture at the cost of noise. If you wanted real details and proper exposure in gcam, which could beat stock, you'd need to rely on long exposure coming from astro mode (toggle to enable in quick settings, and have to use a profile made for it).
[Samsung Galaxy S23 Ultra] Steerpike58:
I have a profile named 'Astro', and I did try a 4-second exposure, but didn't look any (or much) better. I get confused in gcam between profiles, configurations, and settings. Upper-right corner control I can choose between (eg) Balanced-LDR, MaxQ-HDR, and Astro. I presume these are profiles. On that same screen, I can 'load configs', and that's where I have javaSaBr S23 AGC91v13 v40 Sharp, Smoothie, Soft, Ultra Sharp, etc. Then lower left, there's a gear icon that lets me choose 'photo settings' like HDR, Timer, etc.

I'm not expecting to get good results with this particular scene; it was just a conveniently dark scene to play with. If GCAM comes into its own with a bit more light, I'll find another test scene. Presumably one that can be taken comfortably at around 1/2 sec?
[Samsung Galaxy S23 Ultra] MatioNoir:
I have a question if you could help me.

On your older Gcam configurations there was a blue ring that was forming around the round picture preview signaling the fact that the image is being processed but in your latest Gcam configs and versions that ring doesn't appear anymore. Is there a setting to get it back?
[Samsung Galaxy S23 Ultra] PhilMorin:
The right is gone but you still have the saving indicator at the top

[Samsung Galaxy S23 Ultra] Baker35:
it's nice that someone else can squeeze something out of agc, but every time I test new updates and there are no major differences, which would be nice, I use agc9.1 java and 9.2 mazar but I always come back to Lmc 8.4 because we have editing options dng files, focusing in a given place in night mode works and the image is more pleasing to the eye and sharp, in my opinion it would be better to introduce these functions to agc and that would be enough, especially the processing of the dng file, because the ones from agc are not suitable for anything .

My biggest gripe with the S23 ultra camera is the inability to freeze subject motion.

I just tried this APK and the subject motion blur is still bad--I compared against my pixel phone and the pixel still does a better job vs. the gcam APK on my S23 u.

What are the settings I should use to get no subject motion blur in shots? Nothing is immediately obvious.

Appreciate it--I haven't tried AGC yet, was using LMC. For AGC + Javasabr + Sport mode, with sport mode does it do multi-frame, or just single-frame capture? I glanced (very briefly) at AGC info and from what I could tell, sport mode uses just a single frame, so no HDR+ (?). Thanks again.

Hi guys, Does anyone know if there is a modified version of the Samsung camera application or the possibility of modifying the settings using an ini file ? I would really like to be able to use the basic application without the Samung preprocessing which ruins the photos

You can't modify it without root... But if you have root you can try to modify camera driver files
[Samsung Galaxy S23 Ultra] Davids777:
Thanks but files are like ini files with XML datas or it's harder to edit ?
[Samsung Galaxy S23 Ultra] Baker35:
Hello, after many tests in agc 9.2v10 java45, I tested mainly a raw file for processing and I found that this file is not suitable for anything, applying colors in this file, blurring makes the photo fall apart, it is better to process a jpg file from a stock application, expert raw or pro raw samsung has little detail but these files can be nicely processed and colored, in gcam Lmc 8.4 raw is also different and in my opinion much better, I also downloaded agc 8.4 300 v11 nicam v11 profile and raw is also better for processing there Interestingly, it has tint colors in every profile, even HDR.
[Samsung Galaxy S23 Ultra] JavaSabr:
What is your issue with raw? Any sample?
[Samsung Galaxy S23 Ultra] ajarosz:
Are you sure that you are using the correct profile for the files in LR? I have just checked and RAWs are more flexible than JPGs from AGC and I do not see that much of a difference between LMC and AGC when hard pushing the files...

And I was lately in Italy, and I had no issue with RAWs from AGC.
[Samsung Galaxy S23 Ultra] Baker35:
during the day, when taking photos, there is no difference between lmc, expert raw and agc, the difference becomes when we take a photo, e.g. at sunset or hdr, and by reducing or adding orange or yellow color saturation to -10 or +10, the color begins to disintegrate and appears pixelosis, it is clearly visible when processing photos in Lightroom on a computer. When I have time to do a test at sunset, I will post two identical photos after processing.
[Samsung Galaxy S23 Ultra] Baker35:
try an hdr photo at sunset and upload it to your computer in lightrom.
[Samsung Galaxy S23 Ultra] ajarosz:
For me seems ok. Raws from AGC with some quick editing. One with lifting shadow, the second to show the sky to try different processing to check when it fails. I have like 1.5k RAWs from the last 5-6 weeks, and so far I have not found a single one when I could tell, that something is off with it. Sometimes it might be the case, that I cannot recover something, or shadows are too deep and become noise when lifting them, but it is my fault for choosing the wrong parameters.
[Samsung Galaxy S23 Ultra] Baker35:
then there's something wrong with me. More generally, what profile did you set for these photos?

then there's something wrong with me. More generally, what profile did you set for these photos?
[Samsung Galaxy S23 Ultra] ajarosz:
For AGC I am using pixel profile, while for lmc it was adobe color.
[Samsung Galaxy S23 Ultra] Baker35:
first I will try to remove all agc and lmc applications because I have several and they may cause errors, I will install one agc and clear the cache, are you using ultra sharp, sharp or medium? I still miss focusing in the night mode, because the night mode always catches the center, and in LMC it works fine in the night mode. Are you using Raw in HDR? because there is still a problem with the tint color.
[Samsung Galaxy S23 Ultra] ajarosz:
I use medium, and sometimes soft. I use rather LDR profiles, as JavaSabr said, it is not possible at the moment to have at the same time good JPGs and RAWs without tint at the same time.
[Samsung Galaxy S23 Ultra] Baker35:
In LMC 8.4 and AGC 8.4 300 it works well in all TNT shade modes. But it's good that at least in LDR it's ok.
[Samsung Galaxy S23 Ultra] Baker35:
Is it better to have raw compression on or off? any difference other than file size?
[Samsung Galaxy S23 Ultra] JavaSabr:
For example in my config for LMC you don't have "true" HDR as we have on my AGC config
[Samsung Galaxy S23 Ultra] JavaSabr:
This compression is without losing any information
[Samsung Galaxy S23 Ultra] Baker35:
yes, I already know, the difference is not big but it is there, in AGC 8.4 300 I don't know how "real" HDR is, in it the tint shades are like yours in LDR, to make HDR you need to have the HDR balance or max profile turned on and to this is a night mode in which you can't set the focus point to what you want, since you can set the focus in night mode in LMC and AGC 8.4 300, can you do it in AGC 9.2? because it's a bit irritating if the focus point only works in the center.
[Samsung Galaxy S23 Ultra] JavaSabr:
It's limitation of AGC 9.1/9.2...
