What metadata info is attached to a photo?

I wonder on popular custom ROMS what metadata info is typically attached to a photo, if I have GPS settings off? Email, or real name? Could a person (as opposed to law enforcement) somehow trace this photo back to me ?

I think only info like the focal length of the aperture, the fact that the phone is a SGS3 and the ambient exposure used for the photo.
Things like IMEI numbers wouldn't be stored with this, so they can't identify you directly, just the model of phone you used to take the photo.

Audio files store metadata. Images store Exif data. this data is encoded into the image file. some of it is read by windows but you can read alot more data from an exif reader. here is what mine puts out.

as you can see, there is Nothing in there except the camera version and the Rom you are on.

awesome idea!
just installed it, gonna test it soon.

Looks cool. My wife wants to know "how accurate is it"?
If you're the app dev, would like to know how it's calculating things. We're both university-trained amateur/hobby photographers and I'm a programmer, so i'm curious

It's quite accurate, but you have to understand the hardware limitations. This is a reflective light sensor, unlike incident light sensors used by companies like Sekonic. Stray light can put the sensor off by 2-3 stops.
The light sensor will output the amount of light detected in terms of lux. Using a few calculations, this is converted to an EV value. you can read more about this here: http://en.wikipedia.org/wiki/Exposure_value#EV_as_a_measure_of_luminance_and_illuminance
With the EV value, this gives us the current exposure of the environment. Given a user selected ISO and aperture, it is then easy to calculate the required shutter speed for normal exposure.

Desire 530 - Remove over-sharpening and over-saturation?

Has anybody else noticed that the screen on the Desire 530 is massively over-sharpened and over-saturated? It bugged me the first time I used it, and reminds me of the over-sharpening on the LG G3.
It almost seems like a filter has been applied to the entire screen. Oddly, the over-sharpening/saturation is turned off whenever the camera is used, or whenever a video is played, and it remains this way until the screen goes to sleep, the over-sharpening/saturation then returns when waking the phone up. The screen looks great without the over-sharpening/saturation IMO, small text is much easier to read because there are no sharpening artefacts and it's generally much easier on my eyes.
Does anybody know how to disable it permanently? It's not a massive deal, as I can always start up the camera to get rid of the ugliness, but I'd like the screen to look natural all the time.
I've tried to capture it in the photos below, the normal screen (over-sharpened/saturated) is on the left, and the more natural screen (after using the camera) is on the right.

Question Camera switch to super macro bug ?

Hi guys,
I'm not sure if I'm the only one having this problem, but when my phone switches from the main photo sensor to the super macro, there is a clear difference. There is a shift and the colors are not the same.
Here a video to show the problem :/
New video by Céd Zhg

Same moment, same distance but two photos very different :
the first one is the main camera, and second one is the super macro. The switch is not natural

It's a different camera on the phone isn't it? The switch would be expected. The phone isn't doing everything with just one camera/lens.

This is correct. Super macro mode uses the ultra wide camera. Every 'zoom level' in super macro mode just crops image from the ultra wide camera.

The difference would not be too noticeable? Especially in terms of colors and angle!

Question Xiaomi 12X LED Flash

Hi, I received my new Xiaomi 12X today and noticed that the LED flash on the camera works only upper side as you can see in the photo. It is normal? Shouldn't both LEDs be lit? Maybe someone can check on its 12X does it work in the same way?

Almost became blind while checking it here, but mine seems to use both of them, the lower one seems weaker. Tested with the camera flash and with flashlight on too.
As far as I know, most dual flash setups comes with a white led and a yellow one, so you can get a smoother white balance in your pics. Maybe the camera AI choose how much of each one is used depending on the light of the environment you're taking pictures, just a guess.

When looking with the naked eye, it is difficult to distinguish whether both LEDs are lit. Try cover the flash with a piece of paper and try again. Or zoom in with other phone camera.

Yup, seems that only the top one is on, like yours! (my old Redmi struggled a little to take this picture)

I found a Xiaomi 12 disassembly video and there is only one LED! There is a some kind of sensor next to it.
So everything works as it should, thanks for your time
