Just throwing it out there that, if it's to compensate for refreshrates, it should probably be named "anti-flicker" and not anti-banding. If I see banding in reference to images, I generally associate it with the image not being properly blended and each separate shade being easily identifiable.
Does anyone have an old CRT monitor or tube TV they can try 'off' vs '50, 60, or auto' with? Submit the results, pics or it didn't happen. I don't know if this is the case
Banding is pattern of vertical line in photo. And banding is digital imaging artifact. And banding happens in some extreme or special exposure or conditions. To avoid these pattern you can use Anti-banding feature of camera.
Alright, necroing in...
My device is Yu Yureka CM12.1. But what I've noticed is that the Anti-banding option doesn't change anything when I take the picture of, say my led monitor. But changing the ISO setting does. If we set ISO manually to a higher value like 800, bands will make the image ugly. Even lesser ISO values have banding, but to a small degree. Setting an Auto ISO mode solves the issue. I don't know the technical reasons behind it.
Here's a photo of my led monitor with ISO set to 800:

I am pretty sure you knew about light arts using your DSLR, what about the spinning led? In case you have't seen anything like it .. here are some youtube video about these LED arts.
Well I done the same concept, but as a software
Strobe Light Art is an application for Windows Phone that you can use along with your DSLR or any camera that is capable of setting the Exposure Time. The term Light Art is a form of visual art where main media of expression is light (wiki). We have seen LED used to make an artistic way of displaying light art, and sometimes used with those motorized spin board that displays some analog clock or messages. Along with those cool electronics stuff, I present to you an application that can do the same.
In Strobe Light Art, you can:
1. Create your custom message on the fly.
2. Have your own LED effects.
3. Create your own pattern (future)
4. Save and Restore your patterns (future)
Here are the sample images I taked but using only my Sony Cybershot DSC-W220 digicam
This application was already submitted in the Windows Phone marketplace and it's on the processing of certificate so I'll update you guys once this one is up.
You might want to post the images of your Strobe Light Art creativity here please

As you'll be able to see in the pic, in low lights or even a bit of light the camera has very much noise like burning fire no matter what mode I am using superior auto or manual but when I change ISO to 400 the noise tends to almost disappear but still does, so by not messing things up is this a common software issue? I had tried several camera apps all are the same is this software or hardware/lens issue? I am running on latest 2.257 firmware

Erm, could you post a few actual pictures please? The viewfinder does NOT display the quality of eventual images as it does not apply any processing. The view from the viewfinder will always be hella-noisy. (that's a term, right? Down with the kids, me )
Actual results can be as good as this:

Hello guys!!!
I have a weird issue with my camera app. When I'm in a room with artificial light or low light, I mean not in the dark but not with the perfect light, at the end of the day for example. All the camera modes have awesome results, thanks Sony sensor BUT when I use the Timeshift video mode the result on the screen is very ugly and the light is very low.
Can you tell me if it's normal? When I use the Timeshift burst the result is good like the auto mode, manual mode, etc...
But the Timeshift video is very low light. When I'm in low light conditions, the auto mode and others take good pictures (not perfect but good for the poor light) and the Timeshift video mode is almost dark!
See the difference in same scene, AUTO VS TIMESHIFT VIDEO :
AUTO

Thanks !
As far as i know, this is done to achieve higher frame rates. Like, go to video mode and try 1080p 60 fps. You'll see it's darker than at 30 fps
Yes you're right! So it's normal? No need to return my Z3C?
not at all. In order to achieve higher framerates the ''shutter'' doesnt stay iopen as long thus not as much light is getting in. Completely normal. dont worry about it.
Thank you guys
When you disable the watermark/logo in settings, do you still have a white foggy area above the phone? See photo. I am not sure if this is the just to use as a contrasting background for the black font watermark or if my camera is faulty. However surely if you remove the watermark in settings then the white fog should be removed too as it is not needed anymore?
So do I have a problem or is it normal with all the cameras?

Yes, mine does too. Seems to be Huaweis way of hiding the camera / phone from the shot
Is there any way of doing long exposure shot with this camera?
Huawei specs says that camera has up to 30sec exposure
Hello, everywhere is written that huawei cv60 360 camera is shooting 2k video, but in app written 1920x960 resolution, and this is not 2 k resolution, any thoughts ?

Not that I know of, the software would need to support it and it doesn't appear to at the moment.
Where is 2 k resolution?

In summary 1920x960 = 1843200 = 2K :cyclops: just marketing, nothing personal
This white overlay thing on the bottom of the 360 camera (white beneath huawei logo when on) is kind of annoying. Is there anyway this could be remove view editing the APK file.
Can one get any closer than the XZ1?
That's definitely one of the drawbacks I find on the previous XZ series cameras. Wondering if they've improved it or not... since it's a similar module I think I know the answer.
Here's a crop of a garden spider I took a few days ago.
just tried to take a Macro... it needs about 7-10cm to get rid of the blur... i'll do some advanced testing with Manual Mode and a tripod

Okay... here we go...
Auto Mode:
10cm

9cm (already somewhat blurry)
8cm (totally blurry)
Difference Between Manual Mode an Auto Mode is almost nonexistent
Manual Mode:
Auto Mode:
(Keep in mind, the Imgur compression which destroys the picture.... too lazy to upload original picture)
Oh... and if you think you can just switch to Manual Mode and set Manual Focus distance to the minimum... well, check the two hidden pictures above... this one is the same excep Manual Focus distance instead of Auto... same distance.
So yeah.... it's even worse -.-
Seems about the same as the XZ1, that's what I figured (but with a sharper, cleaner image).
I've been spoiled by my old Lumia 950 XL's camera's macro ability I guess.
We'll have to see if the module in the XZ2 Premium or their newer 48mp fairs any better.
Focus setting will make the difference I think
