[Q] Camera flash output / brightness in ICS - LG Optimus 2x

Is there a way to modify / lower camera flash brightness (output) in ICS?
When taking photos in darker environment, flash 'burns' the photo i.e. colors are washed out and photo is overexposed. I also noticed when the flash is activated during focusing, its brightness is normal.
As far as I remember, this was not the case in GB based ROMs (in which I always used ported stock LG camera app).
I've yet to try out alternative camera apps (zoom fx, ucam...), but I'd like to stick to the stock LG software.
TIA

same problem here,but i used Jbcamera+ for taking pictures (it has great autofocus and the flash is ok) and camerazoomfx for video recording,(the stock one not focusing and the jbcamera+) because the stock camera is bit annoying for me

I havent used the lg stock camera but as you have said the photos are over exposed when using flash so isnt there an option to decrease the exposure? I use the 4.2 Camera and when taking night shots depending on how close the target I set exposure to -1/-2 and get decent low light shots, flash wise that is.

Well, there is exposure compensation on stock camera app, just haven't thought of that before. Will try tonight both camera JB from play store and LG's app with exp -1 and -2.
Thanks.

I thought camerazoom fx only took photos?

Yes, the exposure is way too high. Generally the photos are affected by the flash burns. The only solution i found was to decrease the exposure to -1 or -2.

OK, much better with exposure at -1 and -2 (depending on the surrounding light level).
I just wish LG camera app were a bit more 'intelligent' to figure exposure compensation on its own, but then again it would probably have to rely on some DSLR-like metering methods that would certainly double the size of camera/CCD (and the bulge where it sits) as well as its price...
If this were top priority to me, I'd probably be carrying a 'stupidphone' with an enormous camera at its back (nokia 808, anyone

Desire Cam vs Stock Nexus Camera - still shots

I wanted to create a thread specifically for showing pictures taken with either the Desire Camera ported to the Nexus, or the stock camera app. In my opinion, the desire camera takes better pictures, even if very slightly. But who knows? And maybe we can learn something from each other about how to take better pictures with this awesome phone?
Please put along with your photos:
Camera (Desire or Stock)
Lighting source (indoors/outdoors)
Megapixel level
ISO Level
Changes in brightness/contrast/saturation/sharpness or any relevant settings
Focus (Auto/Off/Tap to Focus)
White Balance
Any other settings changed from default, or relevant information.
Pens at my work
After clicking on link, Right click on picture and hit View Image in Firefox (and whatever is the equivalent method in IE and other browsers)
Desire Camera
Indoor lighting
5 Megapixel level
ISO 100
Tap to Focus (on yellow marker)
Auto White Balance
I should really do some comparison shots, Ive got a stock N1 I can get my hands on, 720p'ed rooted custom etc N1, a stock desire and a froyo'ed desire
I compared the stock camera and the one that comes with CM RC3 and it turns out that both have almost same output. Camera360, however, does a pathetic job sometimes. The night mode (and the enhance contrast mode) on Camera360 does a *brilliant* job though.

[Q] Google Camera vs Camera FV-5

Sorry for yet another camera app battle but so far, I haven't seen the two being compared against each other.
Since I found the Twisty Switch Xposed module, I've wanted to change the camera app into one of these two apps.
My MAIN uses for the camera are just to take pictures of documents [therefore I need the text to be seen clearly] and to take pictures of everyday things [in bright lighting]. I'm also looking to see which does better in taking pictures in yellow lighting [light isn't white bright, but it isn't dark either]. So, which better suits my needs.
Why don't you use both and see for yourself? Obviously FV-5 is going to give you more control.
I can't use FV-5 because whenever I change the ISO mode to lower value the images coming through the viewfinder get very poor framerates to become unusable. It's not a problem of the app or a specific device, both my Moto X have it regardless of apps used, it's just something to do with the Moto X camera.

Improve Camera Quality in Automode?

Hello,
i just got my hands on the Z3 Compact and took it out to test it on a sunny day.
Back home i noticed that the picture quality is really bad in auto mode!
I made a quick comparison picture to my old phone: a Xiaomi Mi2 (not the S Model) with 8m Camera.
The picture shows the text quality of the Xperia Z Ultra Power Pack which is the best example i can do now.
The automode settings are: ISO-800, F/2, 1/50 Sec, no flash
The Mi2 automode settings are: ISO-488, 1/16 Sec (no data on the F), no flash
Directlink:
http://abload.de/img/neuebitmapoksb8.png
And here the same with manual mode and a lower ISO (100 instead of 800 that was used in auto mode):
The complete settings were: ISO-100, F/2, 1/8 Sec, no flash
Directlink:
http://abload.de/img/dsc_0099emqqy.jpg
Heres another example of a picture i took when i was outside (without zoom, i just cut away some parts to make it smaller):
The automode settings here: ISO-50, F/2, 1/320sec, no flash
Directlink:
http://abload.de/img/dsc_0036lujf6.jpg
Any idea why automode causes such very bad picture quality? Any ideas on how to improve it?
Thank you for help!
Why bother so much about the auto mode? You can take such great pictures in manual mode when you play with the settings. In the end auto mode will never be great, because it does what it says: auto mode, it adjusts the settings to what it thinks is best in each situation.
Playing with the manual mode will also give you more knowledge of basic photography.

Auto mode became better over time on the Z1C, I guess they'll keep improving it. Dunno if they made a step back here.

Auto mode will always be handy.. no one wants to mess with settings most of the times.. its a phone camera and if i want manual controls i would pick a dslr. Thats why iphone wins in camera department. Take it out and snap a pic instantly with great output. Even on my galaxy s5 i take pictures on auto and i havent seen anyone setting things up manually each and every time to take a damn photo
Auto mode uses a technique called oversampling to gather information with the 20MP sensor, then heavily processes the photo to whatever the software (Sony) decided was best (post-processing). The idea is you get the detail of a 20MP sensor, in a auto-corrected and down-sized 8MP resolution photo. Oversampling is also why the Z3 has a small amount of "lossless" zoom. (ever tried "zooming" with other phone cameras? It usually leaves you with a terrible blob of digital noise)
As with any automatic post-processing, there are pros and cons. The truth is, the software doesn't really know what you're taking a picture of, so it tries to give it's best guess on correcting exposure, colour, noise, etc. The result you're seeing in the auto-mode photo is a result of heavy post-processing (Noise Reduction), bad focus, and camera shake.
The reason your "manual" photo is better is because manual mode drops the post-processing. It also looks like you were able to hold the camera steadier for the manual shot.
"Auto" mode is far from perfect, but it will often save you more times than you know. Over time, you'll learn the strengths and weaknesses of "auto mode", and you'll know when you need to switch to Manual for the better shot. Auto mode can also be easily improved upon via software updates.
PS: A little trick I use to minimize camera shake while taking a photo is to set a quick 2 second self timer. This will allow you time to press the shutter button and then stabilize the phone for minimal "camera shake"
I have read the z3 Compact camera is great, great, great...but yeah I have been grossly underwhelmed by the auto mode. The auto mode is THE mode...sure have a manual mode if you want...if you have time. But I use my phone for quick snaps...QUICK being the operative word. I want to pull it out aim and shoot. My iphone5 took very acceptable pictures. The z3 compact has shown me grainy, bland looking shots in auto.
I don't get why auto mode isn't the most important mode for designers. It's a phone...not a camera...so make the auto mode work
Yeah, camera is definitely underwhelming. That being said though, it's better than most. My Moto X took absolutely horrid shots for the most part.

Coming from 2 years on the iphone5...I was under the impression that camera technology was pretty well mastered across the board. iphone makes it look easy. There's even an annoying lag between pressing the button and the shot being taken on the Z3...what the hell is up with that?

Well, my z3c is still on the way. I have a question. Will the 8MP pictures I take in Manual mode be oversampled as well?
Because the sensor is still 20MP and if I manually adjust it to take only 8MP pictures what advantage do I have in having a sensor that is 20MP? I never print photos. Only watch it on my phone, laptop or my LED tv which is 1080p and 50" screen. I don't want photos that are too big in file size unless it is benefiting me in some sense other than for the purpose of printing and viewing in very large resolutions. I see that oversampling in auto mode is benefiting from a 20MP sensor but is that the case if I take 8MP pics in manual mode?

By selecting 8MP in manual mode, all you're doing is resizing the photo from 20MP (post processing). The sensor will always capture at its full resolution.
If you know you only want a 8MP photo, there is a small benefit in resizing the photo at the phone:
The first benefit is obviously file size, but before I get into the second reason, I need to explain something first: A picture that has been converted to JPG is considered to be post processed. The compression that the JPG engine performs means your image loses details and thus has been altered. I know I said above that Manual mode means the image isn't processed, but I really only said that for the sake of explaining things easier. The average user does not consider JPG compression as post processing and they probably don't care to know. The truth is, unless Sony allows us to capture images in RAW format, the act of converting all our images to JPG means our images are all being post processed whether we like it or not. The difference between manual and auto mode is really about "how much" post processing occurs. In manual, Sony is most likely just compressing to JPG (and probably lens distortion correction but I won't get into that now) , and not applying corrections like noise reduction.
As for how it may be beneficial to resize at the phone; JPG compression is usually the final step in post processing. So by resizing at the phone, the theory is the image is captured in [email protected] > resized to 8MP while still in RAW format > compressed to JPG.
This means you benefit from the photo being resized before it is "post processed". In theory, this method should leave you with a higher quality 8MP photo versus resizing from a computer. Resizing from a computer means you're applying post processing to an already "post processed" photo.
For the average user, 8MP is more than enough, however, this is not to say all phone cameras should come in 8MP. Keep in mind that there is a big difference between an image captured by a 8MP sensor vs being captured by a 20MP sensor and then resized to 8MP. The 20MP sensor can capture much more detail with proper/sufficient lighting.
@wooki (OP):
Especially the first comparison "Xperia Z Ultra Power Pack", the one you made with the Z3C is nothing but blurred. So what is it you're trying to show/compare? I mean, yes, may the Z3C doesn't come with the best camera on the market, and yes, the "Auto mode" does not always provide the best results. Not really sure you're into photography or not, but what can be expected from a lens not even half the size of a fingernail? Not too much, right?! Get an SLR with decent lenses and a full frame sensor if you need more/better.
However, the attached fotos were one of the first ones I made with the Z3C (in Auto Mode) and think it's quite ok. No processing, just resized them.
@sxtester
I was comparing my Z3C with my old phone (a 2 year old Xiaomi Mi2) which seems to have a very good auto mode. Was just asking if i was the only one who has had a bad automode experience and if someone knows how to improve it.
How do your pictures look like without resizing?
As i'm owning a WQHD Screen all my automode pictures look very bad!
I don't want to set up the manual mode every time i want to take a picture, this phone has a shutter button to make fast pictures and with the setup phase i lose time even if manual mode gives me excellent pictures.

The manual mode uses oversampling as well, if you select a lower resolution. I've compared an auto mode shot with a manual mode shot of the same scene, and both were equal in terms of details and noise. The main difference was that the auto mode shot looks far worse because it tends to use that horrible HDR which just washes out the photo and ruins the contrast to near non-existence. I find that "multi" light metering mode, selectable in manual mode, gives far better results than HDR on this phone.

Furthermore, the pictures from this phone's camera would look a lot better if Sony used a better algorithm for their oversampling.
Here is a comparison between a 100% crop of an image taken using Sony's oversampling (8mp) (former attachment) and a 100% crop of a photo taken at 20mp, and then downsampled to the 8mp dimensions using Irfanview (latter attachment):
I agree....Sony's software is lacking compared to everybody else. Auto mode seems kind of hit or miss. Their camera sensors are excellent, as I believe the iPhone uses a Sony sensor, but the difference being Apple is able to process better looking images with their software. I also have a iPhone 5s, and I must agree that 7/10 times, I'll get a better looking image from the iPhone. In terms of capturing details, i think Z3C is better (as expected), but all my images from the Z3C are on the "red" side when shooting in auto-mode. In the end, the iPhone comes out with the better looking photo because I'd much rather have better colour re-production over slightly more detail that you wouldn't even notice unless you had a photo to compare against.
I still think the Z3C's camera is on par with the best from Samsung's Galaxy S5 and LG's G3 (Sony sensor). It's way better than my old HTC One M8's "ultrapixel".
On the Android side of things, I think Z3C is still top 3, and Top 5 in the Smartphone world (iPhone and Lumia above it).

Sony's approach looks way better because it doesn't blur that heavily. If I want to blur away all the details, I can still do that myself.
This is a bit off-topic, but I don't really want to start a new thread just to ask such a silly question.
I've been playing with the camera app some more and is there seriously no "rule of thirds grid" in Sony's Camera app? I often like to use the grids to assist in making sure my shot is straight.

Really? Sony's approach is full of over sharpening artifacts and -auras, doesn't look better at all IMO.
One dumb quetion.
If i use another camera APP, it will improve the photo quality?

It depends. I choose CFV-5 and PNG image saving (rrather than JPG) and it looks much better then Superior auto, and sometimes better than Sony's Manual mode.

Changing camera auto-exposure?

So as we all know, the Nexus 6 camera sucks in low light compared to just about every other phone on the market. I played with L Camera (camera app that uses Lollipop's new camera API's) and played with the exposure and ISO settings and was able to get very good quality pictures with minimal noise. This makes me believe that the hardware is capable of alot better low-light performance, but on the software side of things, the "default" auto-exposure setting is set too low. Is there any way to change this?
I'm able to get okay results using HDR+, but on apps like Snapchat where there is no control over anything, low-light pics are abysmal.

Possibility best camera performance settings

I know this is an old phone and the new xperia 1 is far better. However, old but not obsolete :highfive: As an owner for almost half a year. I have been using (testing actually as I am not quite sure about the camera) the camera from time to time and here are my thoughts and the settings that creat tge best overall picture quality.
Ratio : 4:3
As choosing 4:3 can have more accurate autofocus then 16:9 and better sharpness sometimes.
Megapixels : 12mp for daily use (19mp for landscape and or objects far away)
From my testing, using 12mp can actually have less blurry pictures(Taking picture handheld). As according to sony tgat reading out a 19mp picture takes the sensor 1/120 seconds, a 12mp picture might be less than that. And since people may argue that 19mp have better detail to the picture while technically it is true. However the sensor is too small and the benefit is negligible on most of the shots.(But you still can see the difference) Night shot will get less noise too. (Its a noisy mess nonetheless )
Edit : Digital zooming in 19mp mode get much better detail than 12mp
Predictive Capture : Off for image quality (Auto if you have a shaky hands)
This is an interesting one. As sony won't tell you that turning this on can reduce chances of taking blurry pictures because the prediction analyze the viewfinder in real time(taking pictures with the dram time to time) which reduce the time of focusing and reading out picture when you press the button. (But pictures taken with it turned off sometimes have better details)
Object Tracking : On
It detects motion and counter any handshake(e.g. When taking photos on a car)
Its great to track slowly moving cars and buses too.
Also, it applies Scene Detection when you focus manually (e.g. Food mode or Tripod mode) which turnning it off and focus manually with a Blue Circle will not.
Auto-capturing : don't bother as it does not affect image quality
Lens correction : image quality
Edit : (offtopic) Steadyshot on actually fix the distortion on camcorder while taking videos.
Buttom line : The xz3 have a great sensor. That's what I can say (not lens, not software )
Offtopic : It will be great if Raw noise reduction comes to xz3 :highfive:
If you have any ways of getting better pictures, I would like to hear from you!! Correct me if I am wrong:highfive:
On Android 9 with software 52.0.A.8.131 no root
Edit : Predictive Capture on may cause ghosting on moving image. Better turn it off for better image quality.
