Hello i have a new Optimus 2X. Pictures taken in a bad conditions have a many smaller white dots and a few red dots. Is this normally?
I think besides the red dot, it's probably normal what u are experiencing.
All of the samples you're showing are on low light conditions, so the white dots are probably just noise. The red dot, i'm not sure, but it can be something like a dust particle on the lens or cover, or even a dead pixel on the camera's sensor.
I think if you take pictures in good light conditions, like outdoor in daylight, you wont have the white dots
Cheers
Try covering the camera (should be a fully back image) and take a picture, then aim at the light or a something white (don't aim at sun not so good for the sensor) and take a picture.
If the white or black images have a odd colored dots, most probably a dead/stuck pixels in the camera's sensor. (this is a hardware problem)
If you see nothing wrong it is just noise.
Is there someone who feels the resulting image from the camera yellowish? especially if the images were taken with poor lighting. should advise anyone using assistive light, but I think it is not a solution because it would be very inconvenient if each will take a picture should turn first light assistive, pls help me. Thanks.
Hi
When i took photos in very Dark place on Pro mode with Below settings there is some white Dots(Spots) on picture(maybe Like Hot pixel):
1- set exposure on 10 (sec)
2- set iso on 800
The spots place is fixed on all photos in this condition...
Is that nature?!
-The Attached pictures is zoomed in.
You probably already have done it, but, are sure your lenses are perfectly clean, I mean, cleaned with a good clening liquid and a proper cleaning cloth?

If lenses are clean, and it really is a pitch black place, and you had the flash off, and the dots stay in same place on every photo, then it has to be
1) micro scratches (from sand / grit)
2) Dust. They could be dust settling on your freshly cleaned lens (static) - I know if I clean my lenses with kitchen roll, it becomes a dust-fest
3) Fault in CMOS sensor. Though I wouldnt have thought the fault would be white dots, as white is after all ALL colours in the visible spectrum, maybe should be red or magenta maybe, but not white. There are different light sensors for each colour If my limited understanding is anything like correct, therefore, for white to be displayed, red/green/blue sensors at that very same point would ALL have to be faulty. Therefore, to me, a CMOS sensor fault seems unlikely.
4) Dust seal compromised. Unless you have had back off it, this shouldnt be so. Return under warranty if knox is intact.
Good luck.

Are you have Note 8?
I tested two other Note 8s and there was same problem too.
My phone is new and there is no any dust or scratch...
The lense is clean and white dots place is fixed in any photos.
Just test it with take picture in Pro mode with 10 exposure and iso 800 in very dark places without any light. Probable you can see this white dots when zoom in the photo too.

Yes, lens is clean.
I tested two other Note 8s and same problem exist.
Please just set the setting like image below and test it:

OK I'll bite. As much as I didn't want to I checked mine. I do have spots but they are only in the lower left (lower right on these pics because of the rotation) and vary from dots to lines. I suspect it's a limitation of the aperture seeing it only happens with a 10 second exposure and 10 is it's set limit. The first pic was in a dark closet and the second is with a thick cloth over the lens. It's not a deal breaker in my case because I rarely if ever would set the exposure to 10 seconds, I'm mainly a point and shoot person.

I think you didn't set the ISO to 800 in these attached pictures, yes?!

I did. Iso at 800 and exposure at 10 sec. Any other exposure other than 10 seconds and the spots are gone for me.
I took this picture in iso 800 and exposure 10, you can see the white spots clearly:

Yup, it looks like stars. Hopefully others will check as well.
My Sony dashcam does the same thing.

I tested the cam at 10 sec exposure and ISO 800, and yes, there are star like spots, but only visible when enlarging the picture, I had seen this happening with othe phones and cameras at no extreme seetings, that is, not entire seconds of exposure, no totally black pitch ambient, In fact I think that this happening only at 10 sec of exposure is not a big deal, when these dots appear, it is in a situation that almost nothing will be captured in the photo, if something appers in the photo, means there is enough light to be registered, and then, you would not notice the dots, as I most surely will not take pictures in these conditions, I am not worried, I take standard photos all the time
It's normal
Okay. Just tested mine. Same thing. However I do have to mention that I frequently take nighttime photos for astrophotography and typically you wouldn't want such a high ISO on a long exposure because it introduces noise to the photo. And 800 is the highest ISO setting that the Note 8 has. Any camera will do this to you. The long exposure will collect enough light by itself to negate the need for such a high ISO. Not really a defect in the camera, just the process of taking the picture.
I am planning to get a new S10 soon. With the new dedicate night mode update, I have a few questions:
1. Is it possible to use Night mode in bright condition(like during a sunny day)? This because night mode in the Pixel phone provide better quality even in bright condition.
2. Is it possible to force Night mode to use the telephoto camera.
3. Is it possible to force Night mode to use the ultra wide angle camera
Thanks!
1. Yes
2. No
3. Yes
Except there is no forcing anything as you just selection the options normally on the camera app interface
Also this is a thread for the Q&A section.
2 is apperently in the works as well for ultra wide angle

2 is referring to the 2x optical zoom lens. Night mode already works with the Ultra wide lens.
Can I also ask if the night mode is actually useable? IE does not require super steady hands or long exposure times? For example with the Ultra wide which has a smaller aperture.
What kind of exposure times are usually applied in the dark? I'm talking about in the outdoors, some street lights, artificial lighting etc.
more than usable

Night mode doesn't need super steady hands. A normal non-shaky hand is enough to get an excellent photograph.
Exposure is based on the lighting available. For me, outdoors with street lighting shot has always been around 1/6 th of a second. Again this always depends on the light available for the sensor you are using.
While on holiday, quite often at the beach, when switching on the camera, all I got was a bright white screen (like the lenses couldn't cope with the bright light)
After I put my hand over the lenses (to create darkness) and removed my hand, they were able to see an image.
Anyone else experienced that?
