Hello,
i take photos from the night sky since serveral years (with smartphones too).
Unfortunately with the Samsung S9plus the stars are not pinpoint like as they are on the Samsung S7. They apear very distorted with a kind of a halo.
Ofcourse the smartphone was not moved during 10 seconds of exposure time.
I did layed it down and used the self timer mode to prevent shaking.
I tried it serveral days in comparison with the Samung S7.
The S7 is always much better and show pinpoint like stars.
The distortion of the stars is visible in the RAW files(DNG) too so no jpeg problem forced by the compression.
Could you reproduce the same problems?
I am not allowed to post links.So how to show you the photo?
Could send you the link of the uploaded photos for comparison.
The dual camera variants of Samsung phones tend to overexpose shots, especially during darker environment.
That's what I noticed, and I'm waiting for the update they sent to Note 9s.

Are you using the telephoto camera? It has OIS driven by digital gyroscopes. Those gyroscopes aren't effective at low frequencies so the OIS will slowly drift around a small amount. 1/5 second is usually the limit for sharp photos. Even when the gyroscopes are turned off, OIS lenses are VERY sensitive to motion because of the lens being on a soft suspension. Walking next to the tripod could wobble the lens.
You also can't expect clear images if you use F/1.5.
Try using the wide angle lens.
I would send a photo to someone of you so you can post it here into the Tread.
Who like to do it?
The camera was layed down on the ground so no shaking or vibration ppossible during the exposure time.
I found no setting that the OIS gyroscope is working in photo mode. OIS is probably only working in video modes.
Even if it works in photo mode, the camera was layed down, so no shaking could happen.
Who of you could make a photo from the stars with the following settings?
Pro Mode
Camera mounted or layed on the ground with direction to the night sky.
Self timer to prevent shaking
Iso 800
10sec shutter speed
F 1.4

Antwort unfortunately the tele lens only works in very good light conditions.
Even in a bright lighted room there is no way to activate the real Tele lens. The camera automatic switch to digital Zoom.
Also in pro mode its not possible to use the telephoto lens if the light condirions are not perfect.
This is very bad because if the cameras is standing still completely and the object doesn't move why not using the Tele camera lens in pro mode?
Very interesting Thanks for the link

The cameras on the Mate 10 are great, but would definitely benefit with some more tweaking. The primary camera performs really well and offers fine tuned control over almost all the variables. I've found that the auto-exposure in low light raises the ISO quite a bit and the picture ends up looking fake, plastic and grainy. This can easily be fixed by under-exposing or by lowering the ISO in manual mode, but only with the primary camera. The front camera always seems to expose for the face. There are no controls to set exposure or focus, and there is no manual mode. Although it performs well in good light, the results are poor in low light and the lack of any control restricts any creative photography. For instance, if I move the camera off my face, it exposes for the background but it doesn't lock. The exposure switches back the instant I reframe the shot. Is there any workaround for controlling the front camera besides using another camera app?
Front facing camera manual focus
I have the same problem, the front facing camera is almost unusable where there is a lot of light.

I have installed open camera, and this app let me lock the exposure of the front facing camera.
any solution found of this? i can hardly use the front camera because of this issue
The front facing camera on the Mate 10 Pro is great for taking outdoor selfies, as long as you want a solid white background behind you. I can't believe more people aren't complaining about this and that there isn't an official fix.
Helo everybody,
I am wondering if there is a way to lock F2.4 lens with 2x zoom no matter lighting conditions? I am so frustrated when we get digital zoom instead of 2x optical zoom because of bad (under 100 lux) in worse than optimal light. It's F2.4 optical stablised lens so why digital zoom? That sucks don't you think..?
honestly, you'll be surprised on how bad the tele lens in capturing light.
You can play with this. Go to live focus mode, turn the blur effect all the way down. This will force the tele lens to be used. Make sure dual capture is ON.
Now go to your gallery and find that pic, compare the picture in Close up Vs. Wide. You'll be surprised on the difference between the two lens.
What boggled me more is the fact that the tele lens is the one that they used for the Slomo mode. You would think that they would use the main lens with brighter aperture for something that requires soooo much light.
Basically, I've bought the Mate 20 Pro and I Collected it today from carphone warehouse.
The selfie camera is horrible, there's an automatic beauty filter that's applied to your face to smoothen it out. Even my hair is smoothened out.
Right now, because of this, my S8 Plus' front facing camera looks better in terms of colour accuracy and image quality.
Once you take the portrait shot, it says "Sharpening image" and then when you view the image in your gallery, yes, it's a lot sharper, however why does the live preview have this beauty effect on even when Master AI turned off??
It's making my face extremely white and pale for no reason at all.
The "colourful" filter modes too that remove the backgrounds to add cool colour effects also doesn't work in the live preview. It's only when you take the picture shot will the image itself in your gallery appear with the colour filters which is extremely annoying.
TLDR:
Automatic beauty mode that smooths your skin and hair
Cannot turn it off
Background colour filters not working properly.
Selfie quality
How is the selfie quality compared with s8 or other smartphones? Its really terrible? I tested yesterday the front facing camera. My opinion is, its mutch better than p20 pro

After you switch to selfie cam, switch the mode to photo and there wont be any beauty mod apply.
I have the exact same gripe. I'm always taking selfies with my son in the morning and both our faces look washed out. I can't stand it when something basic such as this cannot be right. Although I like every other aspect of this phone. If there is no software fix for this I might have to go back to my iPhone.
The Selfie Cam Lacks Auto-Focus - So the distance from face to phone will make a difference in a crap image or a highly detailed image.
Obviously take steps to turn off beauty mode as well.
There's face brightening going on with the front facing cam. Is it anything like this video?

Did @Leechoonhwee suggestion above help you fix the issue?

By this, do you just mean setting the slider all the way to 0 ?
Go to selfie cam then turn it to photo instead of the default mode. This improves it. Also hold the phone steady after shot as I believe it's taking multiple shots and stitching them so it is better quality if you hold still. ie: "Sharpening photo hold the phone steady" etc.
I first noticed that my optical x3 photos had a fair bit of digital noise to them.
I then tried pinching to change the zoom and I couldn't see any transition between the lenses when going from 2.9x to 3x. You should be able to clearly see the transition between 0.9x and 1x
After covering up all the lenses one by one with my finger and changing the zoom level, I can see that the x3 view (which should be using the bottom left lens, as you are looking at the back of the phone) is only blocked when I cover up the standard lens (top right)
Can anybody else verify this? Is this some strange intentional behaviour or a bug?
Confirmed on my device too as a bug when viewing the screen.
However, if I try taking a photo the camera switches to the 3rd sensor to actually take a photo.
Must be a new 'improved feature'.

IMHO I suppose it's so by design, to allow the user for a smooth zooming experience, and it can be considered a bug only as far as the correct lenses are not used to take the final picture.
I think it's to do with the minimum focus distance to be honest. If you're trying to focus on something far away it will switch but something close it will switch back.
I think, the camera changes at zoom 3x if there is enough light, otherwise it will use the main sensor. I tested this by holding the camera on TV and on my low board, the room was dark.
How is the camera quality? Im coming from S22u
Battery is ok. Zoom definetly not the camera to shine. Ultrawide and standard lens are very good. However, coming from an S22u you might have a downgrade..
Main camera captures a lot of details and offers a very good (and bright) night mode. Ultrawide and tele are "ok cameras". They can take good pictures in some conditions but don't expect much, they are not in S22u or i13 Pro territory. You'll notice too that the default camera app tends to oversaturate colors. Sometimes overly So. I got Gcam for that reason. The front cameras for selfies are also ok cameras. In poor light they are almost unusable for me. I recommend using the main camera for selfies. Find N is a great phone but the cameras are not the highlight.
Cameras on this Oppo are very good. Samsung S22 Ultra is plagued with horrible shutter lag nobody talks about. Not anymore since I upgraded to Oppo find N. And here you have proper 50mm portrait focal length unlike 75 (3x) they now put in every flag****.
