Light meter app uses your device's light sensor to take an ambient light reading and give you aperture or shutter speed calculations for photography.
Note: Does not work on devices that do not have a light sensor. Ad-supported.
So just search out Light meter app in play store and download it.

Name: Smart Light
Smart light is a 100% free (NO ads)! But, it is not just another flashlight app.
When it is dark, your eyes dilate (your pupils, the black spot of the eye gets larger) to allow in more light in to see better. White light is the highest of all energy light, and causes your pupils to contract (get smaller) thus ruining your night vision. Red light is of the lowest energy light your eyes can see, and causes your eyes to contract LESS than white light (or any other color). By default when you load this app, it loads red light at 50% intensity, so while you are looking at the screen your eyes can continue to dilate. You can easily and quickly turn up the intensity of the red light with the slider for more light, and face the screen at what you need to see, illuminating your path while maintaining your night vision. Even white light bouncing off your path can ruin your night vision.
If you need that extra amount of light, you quickly swap to white light with the switch button.
Also, this light uses the entire screen space to produce light, not just a small area or image of a light blub like most other apps, allowing to produce maximum light.
Features: Very small file size, extremely fast loading, easy to use. No advertisements, 100% free!
Download on WP7 Marketplace. Will launch Zune software.
XAP file is attached.
Please rate and or review my app. I would like to get it up as high in the rankings as possible so other people will learn about night vision and stop paying $0.99 for flashlight apps!
good job dude
thx
Can't find the app in my phone marketplace.
As a "proper" camera, the unit seems to be missing some things I'd expect by default. How do you turn off auto-focus an focus manually... taking pictures at night - the stars etc - invariably the images are out of focus.
Also auto-exposure control - you can turn that off easily for images but for videos there seems to be no way to turn off the auto exposure - which makes the end product look very amateurish.
Finally whenever I go out at night, the LCD dims, I can't seem to stop that and it dims WAY too much?
Any ideas chaps?

It appears that you cannot turn Auto Focus off but you might be able to find a third party camera app in the Play Store that allows this
Settings for video are sparse it's true and again there is no control over the exposure etc.
I didn't notice the LCD dimming, The camera doesn't have an auto brightness LCD so I am not sure what's causing that. Turning the brightness up from the drop down notification bar is easy enough though.
Sorry these are not the answers you are looking for but we have to remind ourselves that this is a premium camera not a pro camera however.

Thanks for that. I will indeed look out for such an app. Agree with you that it's not a "pro" camera - but for example - on the iPhone who's video handling is equally dire, there's an app that completely compensates by letting you shoot 16:9 with auto exposure, auto focus and auto-white all turned off at the touch of a button. This camera really does need such controls to make it useful for anything other than "party" videos. Its a big disappointment that Samsung would miss off such obvious controls having taken the effort to make a special camera app in the first place.
there are only 2 focus modes as far as I can tell, auto and macro.
night sky shots have worked fine for me using auto focus though.
I made some nice pictures of a crescent moon without a tripod or manual focus, and it was sharp enough to see the craters on the moon.
using manual camcorder under expert you can set the brightness, and white balance for video recording manually(wb is under the settings gear)
lcd dimming: settings gear - general - display brightness
the settings gear is hidden under the > and the expert mode can be accessed through the mode button.
don't be so afraid to dig a bit through settings.
I often see complaints about missing/misbehaving features in apps when it's all available through a settings screen.
EDIT: apprentice: auto brightness works using the camera sensor, so it only works while in the camera app.
Thanks for that - so solved the LCD brightness, but I've gone through all the settings and cannot figure out how to turn off the auto-focus or the auto-brightness. Put your hand in front of the lens - and both kick in whether you want them or not... any ideas anyone?

As far as I can tell in camcorder mode, the one thing you can set - brilliance- is only relative brilliance - the exposure still bobs up and down like a YoYo.... making the movies look terrible - surely guys there has to be a way to turn this off?
HI, guys. I have a new Z1 on the way. I have read and seen comparisons that claim that the auto modes introduce a lot of noise and that, while the camera is capable of great shots, the software often lets it down.
I'm wondering if anyone can tell me what the best manual settings are to use. I know they will be different for each setting (dark settings, etc.), but is there a go-to group of manual settings that you use most of the time rather than superior auto?
Thanks!

In manual mode you must stop breathing to not shake the device and capture best detailed photo with less or no noise.
You can also disable flash and use exposure to capture bright photos without flashlight.
You can select manual ISO, which is for light sensitivity. Or....
The ISO number is how sensitive to light the camera
is. It's descended from film cameras, then it would be
how sensitive the chemicals were. The higher the ISO
setting the more light your camera picks up, useful
for low light conditions. However, as the ISOs get
higher so does the amount of 'noise' (visible pixels
that aren't supposed to be there) on your photos. It's
up to you to decide what's a suitable level of noise
and how sensitive you need your camera for each
particular photo.
in other terms
The ISO function sets the light sensitivity of the
camera's image sensor (this is similar to the speed
rating of film. The higher the ISO, the more sensitive
the image sensor and therefore the possibility to take
pictures in low-light situations.
If you find the camera is using a shutter speed that is
too slow (1/60 sec. and slower) to handhold the
camera steady and shake-free then you might select
the next higher ISO which will then allow you to
select a faster shutter speed.
F-stop is the measure of the aperture setting on a
lens. The greater the number, the less light it allows
in, which means the aperture gets smaller, making the
depth-of-field more extensive.

We can edit the aperture? HOW??

LOL, we can't edit aperture and this guide was not only for Xperia Z1 's manual mode but every camera is.

Hope you didn't had a heartattack!
There are black spots on the camera viewfinder when taking photos at night, and the highlighted part of the photo looks whitish. Does anyone know the possible reasons?
Your phone may automatically increase the camera's ISO to improve the brightness of a shot taken at night. This amplifies the digital noise and granularity of the photo.
When taking a photograph or video, remain in a well-lit environment for optimal effects, or turn on the automatic light compensation feature located in the upper left corner of the screen.To enable light compens ation when using the rear camera, set the flash to always on.

Thanks for your reply. I tried with this, it is reallly useful.
I'm curious if it's at all possible or if there is an APK release for the camera that allows you to manually control the color temperature/white balance and prevent/force telephoto lens?
I personally use lenses on my Pixel 4 XL and zooming in and having them switch means I have to switch physical lens placement and also can cause suboptimal photos. Additionally, the white balance and color temperature change far too drastically from warm to cool under certain lighting conditions.
Is there any way to manually control these functions at all?
