Getting DOT while taking photos during night time - Xiaomi Poco X2 Questions & Answers

That I am facing the issue of a blue dot appearing in both rear and front camera of POCO X2when shooting against the light in low-light. For example shooting a bulb etc. It is pops up even in daylight when the photo is taken against sunlight, but in day it yellow. Is it a defect? Tell me at the earliest so that I raise a replacement request. Official statement would be much welcomed.

[Q] Problem with Camera? Blue ring.

When I start the camera I get this blue ring in the center of the picture, if I take a picture it will show in the picture as well. Anyone else having this issue?
Is it a sharp blue ring, generated by software, or some kind of artifact like a light leak? Do both cameras have it? Are you using the default camera application? Can you post one of the pictures?

I guess I am the only one with this problem. I updated the firmware yesterday but it's still there, as you can see just the blue or purple ring in the center.
Is that on the shots with the other camera too?
Is it on all the shots?
If not, is there some unusual lighting for that shot?
I ask the last because as a photo guy, that looks like the type of thing that you see with internal reflections with the IR filter over the CCD under some lighting conditions, e.g. an incandescent light just out of the frame at the right angle for that shot. Again, is it on all the shots? Again, is it on the shots with the other camera too? If it is on all the shots you might have a problem, it does look like an artifact.
What you're looking at is refraction caused by light hitting from an angle (like lens flare) and bouncing around on the inside and hitting back at the inside of the glass and the glass is now acting as a backdrop. Just a wild guess. Best thing to try is to block the lens to kill the light completely. Do you still see the blue ring? If so, then it's most likely the CCD sensor.

It's on all shots and only with the back facing camera. it moves when the camera is focusing.

If it is on all the shots, you have a problem unfortunately. I just tested with mine, and you can get a very fierce IR internal reflection with a light source just out of the frame, but it isn't on all the shots of course. (see below)
Bit of a long shot, but if it moves with focusing, it might be some kind of internal light leak from the backlight. Maybe they forgot to install a little baffle or something. Turn the backlight brightness all the way down and see if that reduces it.

Purple veil in photos (mostly outside)

Hello all,
since a couple of days i own a HTC One X and i really like it.
What i noticed when using the camera, when i am outside i always get a purple veil, when changing the AWB it gets green.
pic-upload.de/view-14166734/2012-05-12-19.24.20.jpg.html
magezinepublishing.com/equipment/images/equipment/One-X-4692/large/HTC-One-X-trees-IMAG0070_1340963256.jpg
Now i want to know, has anyone else experienced this? (i have seen lots of pictures with this purple veil even from professional testers)
Is this generally on the HOX or is it a failure in a couple of models?
I read "purple vein" and had to come in here to look.
I was expecting something else...
This is what happens when bright light shines onto the camera lens.
Worsened when the camera sensor is overloaded with light.
It happens on any camera but it's pretty bad on this camera.
Try to block bright light sources with your hand, or better yet, avoid shooting into the light.

Z3 Camera problem: Hardware or Software?

My Z3 camera has terrible white balance in Manual mode ( compared with the Z2, very stable in any light condition), especially under the high light, at some angles, the photo sometimes is overexposured, sometimes become very dark (?!)...here some example photo i took:
Manual:
- when pointing the camera straight to the light
DSC_0324 by trunghieuhd93, on Flickr
- When poiting the camera in lower angle to the light
DSC_0325 by trunghieuhd93, on Flickr
Auto mode: the white balance is better as usual.
DSC_0326 by trunghieuhd93, on Flickr
DSC_0327 by trunghieuhd93, on Flickr
Have any one got the same problem as mine? It is hardware fault or software that can be fixed in the future update?

Can't think of a way to sort this on this phone. The reason is the metering, rather than using "average" metering on manual like other phones, it uses a spot. So whatever you point at determines how bright the picture is.
Auto sorts this by changing modes probably to backlit etc, but then the photo's come out bad quality and fill of noise with no detail.
Unless Sony add average metering we will struggle.
beside this thing, the phone ccan do some really good photo in normal condition...Anyone had the same?
This is a good example of metering and how where you tap influences the shot. The issue isn't with white balance but rather exposure.

ISO 80, 1/64, metering : spot
point at the light means ignore everything else so iso is low and fast exposure. Exposed for the light, ignores everything.

ISO 1600, 1/25, metering : spot
When you say lower angle where exactly did you tap for focus ? was it the wall below the light or the clothes.
if you point at the dark area where the clothes are, camera thinks its dark and ups iso and blows out the image due to light close by.
You want to point somewhere its not too bright or too dark if using spot. if you point at the wall shot will be less overexposed.

Auto shot, ISO 160, 1/32, meter is average
if you want to see the shot of the clothes center weighted is better. It means a circle (little bigger than spot) in the centre of the screen only will be considered for metering. Will ignore the light.

there is no problem, this is how its supposed to work. When you include a bright source in your image it will overpower the others so you have to find a balance if you want to include that light in the shot. Or you could avoid the light.
Spot is sensitive so where you tap to get exposure matters depending on the scene.
SA defaults to average metering which is good when the light is similar across the scene, if there is very bright and dark it will just average everything and result isn't so good. Spot used carefully or center weighted will give a better result than average metering.

Thanks for your analyse. I choose meter: multiple spot and problem solved. I just dont get why it didn't take meter automatically as good as the Z2 (by default)...?
Post your z2 image on flickr.
Oh you removed the other shots too.

Low light

At the club, at the bar, or just in your mom's basement, nighttime is when you come out to play. Rate this thread to express how the OnePlus 5's camera performs when no or low light is present. A higher rating indicates that the camera sensor "sees" lots of light in dim conditions, and that the resulting photos have minimal noise. A higher rating also indicates that when the flash fires, the resulting photo is evenly-lit without any bright spots.
Then, drop a comment if you have anything to add!
Probably requires a little work on the SW, as I've noticed it takes great pictures at times, and then bad pictures in the same conditions at times. Misses one star for low light pictures.
I deduct 3 star for low light, EIS doesn't work in still image & there is no OIS in OP5 (OP5 downgraded from op3 in stabilization) so, in pro mode it's impossible to use 30s long shot without tripod or stands(who the hell like to use tripod in smartphone).
And the normal shots has lots of visible noises compared to advertised, portrait mode doesn't work in low light with flash, (missing on background lights bokeh), telephoto lens which is only 1.5x optical doesn't work in low light.
??????????????????
It's great to my untrained eyes. XD

No the photo would come out terrible. Tripod is a must on any phone with a long shutter time.

Now I ordered a tripod from Amazon, and a separate smartphone holder. I already got a Bluetooth remote that can be used as remote shutter.
If you are experienced photographer or using OP5. can you tell me what setup would be the best to take photos of half moon with lots of patterned light clouds, I tried to take photo of that and the Moon is all blured out to a round bright circle, I tried on different iso and shutter speed, with focus on that landscape sign ...
I'm very impressed with the low light quality of this camera.

It even got the stars from the night sky.
I putted an auto picture for comparison.
Also Consider the loss of quality from the collage app.
If you are interested in the originals or the shutter speed/ISO settings, just tell me.
how is low light photos after 4.5.8 update ? is it still blurry ?

Yes, I provide here the link for the photos.
These are a set of night pictures, all taken in the same place with a tripod and different settings. This was my first test with a lot of different manual settings.
In every picture taken there's the apperture, the shutter time and the ISO in the details.
You can see for yourself which settings took the best pictures.
Remember this was complete night time with just a few street lights.
The download is pretty big, 427MB but they are the originals with the respective RAW files.

Did you use it? Did you notice some grid from small circles when you crop a picture?
First one was done with stock camera, second one with Gcam HDR+

My Pixel 3 Camera sees blue UFOs

Tell me these are UFOs !
Same result with front and back camera with an intense source of light into the picture, such as sun, moon or even home light. There is definitly a flaw somewhere, just hopping this is not hadware related (hopefully not some lens internal reflection), and not just me ? See some crop below where you see the exact reflection of the source light (aka the blue UFO).
first is "why noboby spotted that blue spot ??" and "that is definitely not just me" :
https://forum.xda-developers.com/showpost.php?p=78101209&postcount=16
second are my own crops :
I may be wrong but it looks like lens flare to me.
Yep, lens flare/reflection. Just compared my Pixel 3 to my Sony NEX5N camera and they both have the blue spot aimed at a bright light bulb.
