arc camera jpeg compression level - Xperia Arc Q&A, Help & Troubleshooting

is there any way to tweak the photo quality? i think there is too much compression by default. i take photos using 6mp widescreen mode.

Yeah it's a known problem, i made a test i took the same picture with 6M on, and another with 2M, the quality is almost the same. Hope they will fix the problem with the update soon

if i don't root, are there any marketplace cameras (free or paid) that will let me take pictures and I can set the jpeg compression level?

Even if it's rooted, I haven't come across a method/app where you could change the compression ratio. I hope I was wrong.
Sent from my LT15i using XDA App

Also looking for a way to take better advantage of the camera on this phone. the quality is terrible due to compress

Any Update to this?
Really annoying bug.

I don't sure that the real problem is jpeg compression, it's too high but in macro shots the image are very detailed and beautiful at 100% crop. In the photos taken with infinite focus (landascape for example) they are very orrible at 100% crop. Is possible that the problem is the too long esposure time?
I compared the exposure time of the arc's and a digital camera's photos. Taken the same object with the same conditions etc, the exposure time of the camera's photos are much lower than arc's photos.
What do you think about?

In any phone camera you have a much smaller lens aperture and a smaller sensor size than in even the cheapest and nastiest of dedicated digital cameras.
Thus to get the same image brightness in the same conditions you will either have to amplify the signal (which will increase noise) or have a longer exposure time. Ye cannae break the laws of physics, captain.
Having said that, i couldn't say whether the long exposure time is the cause of the issue or not.

As far as I read, Camera Advance (https://market.android.com/details?id=com.mnapps.cameraadvance&feature=search_result) is able to control compression. JPGs on the Neo are now more than twice as big and don't suffer as badly from compression.

Haven't checked the compression, but I do have raw picture and video samples from the latest 4.0.A.2.368 build.

Tilt2 camera?....

Ok, this camera states its 3.2 megapixels. But the picture quality is worse than the one from my old phone which had only 2 megapixels. Do I need to change the settings or anything?
Megapixels have nothing to do with quality, only size. Make sure you have the largest resolution picked and that it is set to SuperFine. Still, the camera on the TP2 is only so-so.
Wow thats stupid. I don't like the camera at all.
Picture quality also depends on the camera lenses used. HTC doesn't really use great lenses.
Sony Ericsson (I had the SE C702 CyberShot phone before) uses very-high-quality camera lenses, and the pictures it produced were great!

Well, if you have a 8MP camera vs. a 3.2MP camera taking the same exact photo, and you were to print a 3x5" photo from each, the 8MP should still give you better quality than the 3.2MP. The 8MP camera is able to produce 8 mil. pixels whereas the 3.2MP camera can only produce 3.2 mil. pixels. If you were to print the 3x5" photo, the more pixels, the clearer the image.

Again, that's not a quality issue, per se. Anytime you increase the size of a photo without increasing the number of pixels used to display it, the pic will suffer because things like compression artifacts and aliasing will be more pronounced and visible. Not that these things aren't present in both the 3mp and the 8mp images, they will just be more noticeable in the 3mp image that is displayed at the same size as the 8mp image. That's the real value of more megapixels, the ability to increase print or display size without the ill effects. But that has little to do with quality.
I've been a pro photog for the past 18 years and shooting digitally for magazines since 1997. I started with a sub-1mp camera back then and the quality was fine, but the low pixel count limited our ability to use digital pics for more than just 1/4 page shots or smaller. By the time we got to 4mp cameras we were using them for full page spreads without issue. An 8mp camera can now yield a decent two-page spread. Still, the quality of pics hasn't been increased with more megapixels, only our ability to display them at larger print sizes.
It's easy to confuse megapixels with quality and manufacturers share much of the blame for convincing consumers that more mp=better quality with their sales shtick, but when you understand that quality is not necessarily tied to size, you realize that application is the main factor. For instance a 2mp camera can shoot very high quality 4X6 photos, but blowing those same pics up to 8X10 will reveal the weakness in megapixels, not quality. At the optimum size for a particular mp format, more mp does not yield higher quality, only higher storage and processing needs. It will give you more flexibility in cropping if your skills with the camera are lacking, and more format choices when printing, but not higher quality.
So how would I get the best quality out of my camera?
Have you installed the cab that gives you more camera settings? It gives you a SuperFine setting unavailable on the stock setup. Do a search for it. Also, make sure the lens is clean. Handling the phone often causes fingerprints and smudges on the lens that reduce photo quality.
Thank you so much, do you have a link or know the name of it?
The one I found is ExtraCameraModes.cab.
Here ya go.
Ok, it didn't change anything haha. But thanks anyways
I thought it comes with Super Fine by default. Anyway, I've always had to play around with the light settings the get the color I wanted. I set the ISO at 200. And lighting also takes a toll on the quality of the picture.
Anyway, the camera sucks. i wish they had a button to turn off auto focusing when i need to take quick shots lol
Cameras on cell phones are more of a convenience than a sophisticated capture device. While some actually take fairly good photos, I wouldn't expect too much from any of them. They certainly aren't designed to replace a good point-and-shoot.
OK, well thanks for the help everyone!

[Q] Neo - Question about camera compression

I'm thinking to buy a Neo this week and it will be my first Android phone. In a few reviews I've seen some complaints about the .jpg's being over compressed using the stock camera app. If you use a different camera app are you able to set it for less compression and better pictures?
Hi mattarse
The jpg compression is fine as it is, I believe the discussion on the compression has been started due to very high expectations of the camera in the new xperia phones. The camera IS very good I think considering it is a mobile phone with a very small camera sensor.
Pictures will when you magnify them on your pc never look as good as a dslr or newer compact camera with bigger sensors and better optics. This is probable what started the jpg compression discussion as it would have been nice to just change the jpg compression level and have super sharp pictures even when you zoom in.
The Camera Advance app will give you the option to change the compression but my own tests show no visual difference from the xperia camera app and the picture from camera advance. File size differences was 1MB from xperia camera and 2.2MB from camera advance app.
Camera360 Ultimate will give pictures at the same sizes as the xperia camera app even when you select the finest compression level.
I personally prefer to use the xperia camera app compared to camera360 and camera advance.
I have allways enjoyed photography and normally use a dslr. This is actually the first mobile phone where I have started to use the camera as I have allways disliked the picture quality from my older mobiles. It is amazing to see pictures at iso 1600-2000 being useable from this small camera, the low light performance is very good and the dynamic range under sunlight is also very good.
I have the xperia arc and not neo, but I belive the camera is the same on both mobiles. Have seen some samples from neo where it actually looks like it is producing better pictures, could be due to different optics in the slightly bigger mobile or just differences in firmware.
Well I've bought a Neo for my wife recently. But was surprised also to see the size of the files for an 8mp camera. I was also surprised there is no option for the level of compression.
What is more important that the camera does not produce good quality for darker rooms.(in a room with 15*10W halogen light bulbs). The pictures have a visible yellow-greenish tint and a lot of noise. I haven't tried on outside just yet.
May be my expectation are too high. But I still think this is a marketing trick. They could have easily put a sensor with less density (5mp or 6mp) which is supposed to produce less noise.

I do believe the exmoor sensor has improved low light performance compared to a regular mobile camera sensor. But this is still only a small camera and even my dslr would struggle indoor with only artificial lighting unless flash is added.
Have only shot a couple of low light pictures with my arc both outside and inside and agree that pictures especially at iso1600-2000 contain a larger amount of noise. I would say the pictures are very good compared to my old mobile which was useless in low light and good compared to my compact camera.
You can change the scene mode to make the xperia use slower shutter speeds and lower iso, that will give you some very nice scenery shots in low light with little noise. I have to my surprised shot a few sharp fotos at 1/4 shutter speed in low light, that would not be possible without fixed mounting on my dslr or an extremely steady hand.
You will ever only be able to archive good low light pictures with expensive slr and optics. One thing I have learned using slr is that light is king, you can not get enough light if you want sharp, good looking, strong colors etc.
Now you got me interested in doing some tests to compare the low light performance with my dslr and compact camera
Well hygge, I am quite an amateur in shooting but I also know from my extended zoom camera that noise in low light is a nightmare (at least I use Program mode and not automatic ).
I really got the phone form several days and did not had the time try it good. I've just changed settings from 6mp 16:9 (strange for default settings) to 8mp.
Then the LED flash came on automatically. But the result was not good. (3 from 4 shots were with yellow-green tint and one was too bright (or is more correct over-exposed). But I must confess the scene was complicated if this matters at all: my baby in the bathing tub. So there is water, reflection.....
But anyway I put my bet on the dslr with a huge distnace

That would have been a nice picture, but it do sounds like a challenging picture with the reflecting. Remember to record movies of your baby in the bathing tub. My daughters now 3 og 5 years really enjoy looking at short movie clips of them as babies splashing in their bathing tub
(they love playing games on the xperia, mostly drawing apps )
What I have seen so far is that the xperia tend to prefer low shutter speeds in low light situations. I still only have a handfull of shots to base my conclusions but with flash on it was using 1/25 sec shutter. This is too slow taking pictures of moving kids, you will need 1/60 or even 1/120 which is normally only available on slr's. Without flash it has been 1/8 and high iso, must admit it was under circumstances I would never have used my dslr without flash and maybe a bit unfair to judge the xperias camera capabilities.
I agree that the wrong color balance will totally screw up the pictures, have you tried setting the white balance manually in the camera? A setting I have not yet changed on my xperia and are not aware what options are available.
I have now made some quick comparisons of my three cameraes under low light conditions.
Might upload test pictures later when I have the time, for now you will have to trust me
Camera 1. Xperia Arc 8MegaPixel
Camera 2. Olympus u Tough 12MegaPixel
Camera 3. Konica Minolta 5D dslr 6MegaPixel
Test 1 without flash
Xperia 1. Kamera advance app with lowest compression, no flash
ISO: 1000
Exposure: 1/8
Olympus 2. Default settings with disable flash
ISO: 400
Exposure: 1/4
KM 5D 3. Full auto, no flash
Could not focus, too little light, camera suggested 3-4 sec shutter speed
(was using OEM lense with bad aperture which gave it problems focussing, could have used a better lense but decided to use OEM lense to keep the comparisons fairly)
Results:
Olympus had only a tiny bit more details and allot more noise, picture was looking very bad up close.
Xperia Arc, even at iso 1000 the noise was lower than my Olympus and the picture looked more clean with nicer colors. I definitely prefered the Xperia result.
The olympus will not go lower than 1/4 shutter speed and iso 400. I selected night scenery on the Arc and got a picture with iso 160 and shutterspeed 1/2. This picture had even less noise but was slightly blurred at 1/2, need a more steady hand but still a very useable result.
My DSLR would not take a picture without focus.
Winner:
Xperia Arc, higher shutter speeds and a cleaner picture with less noise. I was surprised to see the loss of details on my 12MP Olympus at ISO 400 compared to the Xperia Arc.
Test 2
With Flash:
Xperia 1. ISO 400, shutter 1/24
Olympus 2. ISO 100, shutter 1/30
KM 5D 3. ISO 100, shutter 1/60
Result:
The Olympus with flash and ISO 100 gave a sharp, low noise picture and the 12MP provided better details than the xperia could show. The flash on the xperia is not very strong and it was not possible for me to configure it to use lower ISO than 400. The xperia arc picture did give a nice result with low noise.
The 6MP DSLR with flash give the same amount of details as the 12MP Olympus, my old DSLR is still going strong and a better lense will give an even sharper picture
Winner:
KonicaMinolta 5D wins, followed by Olympus. Xperia Arc still gave a nice result but with less details and more noise than the other two devices.
One last test at a really dark area without flash also proved xperia arc to be the winner. My Olympus would not go lower than 1/4 iso400 while xperia used 1/8 iso2000. The motive was only visible on xperia arc and even a fairly noisy picture at iso2000 is better than no picture at all
My own conclusion is that the xperia arc/neo is really good at low light performance and even outperforms many compact cameras, but the the weak flash give some serious limitations. The low shutter speeds will probably also be an issue taking pictures of moving motives in low light.
(did shoot a couple of shoots with sony camera app and did not notice any difference from Camera Advance, I used the 3PP camera to use as little jpg compression as possible but I doubt the pictures visually differ much)
It would be interesting to do some tests during daylight as well, it will not benefit from the improved low light performance compared to other camera sensors. I am curious to see how the dynamic range of this sensor is, can it compare to my Olympus compact camera then it would be a serious contender as my primary point and shoot camera as long as flash is not needed.
Thanks forthe replies - I'm not expecting amazing things from camera on a phone Just want to make sure that software isn't unnecessarily hindering the hardware.
It also looks like it will be a couple of weeks before I pick one up...Unless i opt for something else in that time, but for a smallish screen size Android phone this currently looks the best. I do wish it had gorilla glass - but you can't have it all
Now I've found a confusing thread about in line remotes on the headphones that I need to figure out (yes I do seem to put way too much thought into these things!).

I think the yellow green tint you're seeing will be from the lights in the room - you see this on most cameras of any quality, if you have a white balance setting you should have one for indoor/halogen lights. It's also normally easy to fix in Photoshop.

[Q] Camera quality

I read in several reviews that the camera quality isn't as good as expected/thought. Is this pure hardware related? Or is it possible that the photo quality can be improved by software updates?

The photos I have been taking have been miles better than my Atrix, Craptivate, or N1 could have. I think a BIG part of the issue is that many users are not comfortable with the instant shutter yet, and are used to the old smartphone camera game of anticipating your shots by pressing the shutter button a second earlier and then settling in for the shot so the timing is right. That is not necessary with this camera, so the image will snap when they are "settling in" or moving to follow the subject and will be blurry. Also, just remember to tap the subject in the screen to focus before you snap the pic. I have noticed much better low-light pics than any of my old devices...
As to the much beleaguered argument over 8MP vs. the ("only") 5MP of the GN's camera, that refers to image capture size, meaning that the 8MP image will be able to be cropped better than the 5MP one- that's it. So if you frame your photo's correctly (how you mean the image to look), it is a non-issue because there is no need to crop (IMO).
Thanks! But, do you think a ROM update can improve photo quality? Or is that impossible?

Not impossible, but any optimizations would be software only, so things like shutter lag, UI of the camera, and filters, etc.
I actually did a blog post on the camera quality. It wasn't scientific in any way, but I came to my own conclusion that any quality issues may be down to agressive ISO and / or JPG Compression and / or Noise reduction.
All of those are fixable in software - but make your own mind up: http://www.thegreenrobotblog.co.uk/2011/11/samsung-galaxy-nexus-camera-sample.html

Shutter Speed and Image quality

Hi everyone
I have a request if someone could help me out?
The shutter speed of the One X is 1/2500th of a second; This is really fast, or maybe too fast? Extremely high shutter speeds can negatively impact image quality and decrease the Signal to Noise raito in a picture since it will come out darker. I was wondering if anyone knows a way of decreasing the shutter time to perhaps 1/500th of a second? I'm fairly confident it would get rid of the noise in our One X pictures that remains there even when the ISO is set to 100 and the picture is taken in fairly good lighting. Thank you
The noise is just compression from the stock camera app, try LG camera, has a much better quality and detail to the picture.

interesting point. From my understanding, it is a problem of the very aggressive compression as stated by the fellow above.
Whatever happened to that camera mod that fixed the compression in the camera pictures?
Has anyone ever reviewed or compared the modded camera with the original and the competition(sgs3 and iphone)? I think it would finally do justice to the hox's camera

The shutter speed is NOT fixed on the One X (check the EXIF Data on your photos) and if it was, it certainly wouldn't be 1/2500th... 1/20th of a second would be more realistic.
The shutter speed itself has NO impact on signal to noise ratio. However, an indirect result of a fast shutter is that the 'gain' on the CCD is increased (commonly defined as ISO speed). The greater the gain, the more sensitive the CCD becomes, and thus increases in noise. This is why night time pictures are far noisier than bright daylight ones. ALL of this assumes a fixed aperture lens (which most camera phones are).
The real noise issue is twofold...
1) The lens is small, and although it's F/2. that's F/2 of a lousy size lens.... in essence, it's too small to capture enough light to be a decent camera. This then results in the gain of the CCD being very high and producing noise (a bit like the buzz/hiss of an amplifier turned up to max).
2) The compression using in HTC's JPG storage is quite aggressive, resulting in JPEG noise/artefacts. Whilst not noise from the camera per se, it just makes the images even worse.
ALL digital cameras suffer from noise, but the professional cameras have far better noise reduction, massive CCD's and dedication image processing DSP's that simply leave a humble One-X in its wake. The long and short of this is:
Camera phones for genuine photography are a very bad idea, and until there's some amazing technological breakthrough people are deluding themselves about the quality of image that can be obtained from them. That's not to say you can't get great photos, you can, but the image quality simply isn't there.
http://forum.xda-developers.com/showthread.php?t=1765416&highlight=camera+mod
That fixes the JPEG compression issue, but video recording is still not a perfect 30 fps. Frames are dropped at a rate of about one a second, but it's still a huge improvement over stock.
I think it is possible to set shutter speed of the camera module, but HTC seems to have prioritized sharper shots at the expense of higher sensor noise. It is a reasonable compromise for these situations as it is not easy to hold a phone still for long periods of time. Perhaps HDR mode might be able to help, but that is only for still shots.
There is hardly any or no difference between LgCamera (or any of the camera apps) and the stock app, videos are smoother but pictures are very much the same.

Yep ive changed settings and took many pictures, they all turn out pretty much the same apart from certain focus differences.
Lgcamera and other programs have the same problem. The image appears really "grainy". It's not digital compression but rather the photos turning out like that. This in turn affects image quality. Even images taken in daylight are grainy; take a picture of the sky and you'll see what I mean. Zoom in a little and you see it. My Sensation XE had a better camera than my One X, mainly as the noise was practically non-existant and images came out very detailed. It seems BSI sensors perhaps generate more noise? Or it could be that heat can result in increased digital noise; ISO increasing results in more current to the sensor to pick up more light but the heat generated as a result produces noise. Since the One X heats up around the Camera area, it could be possible that the Tegra 3 chips are located there, providing constant heat that also unintentionally hesting up the sensor and resulting in increased noise levels in images?
If either if you are rooted, you should really install the HQ Camera mod. It modifies the settings of the stock app, and you can easily get 4MB pics with really good sharpness and colour. High ISO noise is less too. Really works wonders, and I'm really really really picky about my photos (retired portrait photographer)

Camera Tips for Indoor

Hey guys,
I am having trouble taking good pictures with indoor lighting. The first problem is that the viewfinder (or the image on the screen) is not very smooth. It's jittery and lags and its super annoying. How can I improve the speed of the viewfinder so I can frame shots better?
I also hear that the LG has fantastic low light capability. However, with indoor lighting (fluorescent bulbs) I find the images have a lot of noise and the details appear very muddy and very oil painting-ish.
I don't have any problems during sunlight but indoors, the G4's camera is a mess. It's slow, jiterry and all round annoying to use. Any help would be appreciated!

I haven't tried it on my G4. But on other digital cameras, I have seen the displayed preview screen image get jerky in low-light when aiming the camera around.
My theory is that, to make the image bright enough, the camera needs to take a longer preview exposure. Capturing the image for the preview screen works the same way as taking an actual picture, of course. In bright light, maybe the sensor takes a 1/500 second exposure to generate the preview. But in low light, maybe it needs a 1/5 second exposure to make the preview image bright enough to be useful on the sccreen. So now it can only take a max of 5 preview images per second, and the screen will look jerky.
The muddy details, and looking like an oil painting, are at least in part due to the image sensor's ISO value being turned way up, due to the low-light conditions. Some of it may be due to the JPG compression settings, and perhaps noise-reduction. Pictures taken with the flash should help with this, as you're providing more light, and therefore the camera can use a lower ISO value, for better image quality.
You could try taking the same picture in Auto, then in Manual mode. Turn the ISO value down in Manual mode (to maybe 200, 400, something like that), and slow the shutter speed as needed for a proper exposure. In the Gallery, you can check the Details for the picture taken in Auto, to check the ISO value that the camera used. Use a lower ISO value for the Manual mode picture, and see if the results look better. Doing this with the flash turned off should help make the difference more apparent.
You can also capture JPG + RAW in Manual mode. The RAW files do not exhibit JPG compression, or other processing, they are straight from the image sensor. So you may get less muddiness and oil-painting effect.
..
mufaa, can you post any example indoor pics you've taken? That might help provide some context for what you're seeing.
What are your requirements for the picture?
Do you have a moving subject that demands a fast shutter, or can you afford to use a slower shutter speed?

Zoom into the picture and you will find details buried in blurry oil painting like smudges. This happens in bright pictures as well. Is this how the sensor on the camera is?

What are your requirements for the picture?
Do you have a moving subject that demands a fast shutter, or can you afford to use a slower shutter speed?

I usually shoot with subjects (my family, nephew, etc.) and I need the viewfinder to be fast. Because the viewfinder is so slow, subjects come out blurry even with the slighest movement. I also have to have a super steady hand.
This wasn't the case with the iPhone 6 i had. I just turned on the camera and snapped away.

Reboot or try force stop on the camera app. I've had mine get like this occasionally but force closing the app or rebooting fixed it when I opened it again.
If that doesn't do it, you could have a bad camera. There were some people complaining about camera problems in early June.

Oh boy. I will try that. I have rebooted my device multiple times and the result has been the same though.

somebodyyy doesn't know how to use manual mode for iso

Maybe try clearing the cache and data on the camera app. Also, check that the laser window next to the camera lens is clean and unobstructed. Most of my pictures, even in lower light are very sharp when zoomed in.
Gotta be a bad camera or focusing laser.

Can you share some low light/indoor pictures of yours, and what settings you used to take those pics with?
That sample pic does not appear to have the EXIF data where we could check the ISO and shutter speed etc. that you used, can you check on your camera or source image what the settings were?

The sample picture looks fairly normal to me. That is, it looks like ones I've taken on my G4. I believe the effect you're seeing is partially noise-reduction done by the camera processing, but I'm not 100% sure. A high ISO value will also contribute.
Now I'm wondering if maybe I misinterpreted what you meant in your original post. When you say the viewfinder is slow, do you mean just the jerky image if you move the camera around? Or that the pictures themselves come out blurry?
With only so much light available, the camera typically needs to use a longer exposure to get a bright-enough picture. A steady hand helps, as does OIS, Optical Image Stabilization. But neither of those can help if your *subject* is moving, of course.
You have 2 choices to make a moving subject sharper in low-light:
- Add more light. Use the flash if you aren't already, assuming the subject is within reach of the flash (probably around 10 feet, max). This will change the look of the picture, making it look more "harsh", but the added light should improve the image quality. With more light, the camera can use a quicker shutter speed.
- Raise the sensor's sensitivity, by using a higher ISO value. Effectively turning up the amplification, and allowing a quicker shutter speed. But as most of us have experienced, when you turn up a weak/noisy signal (car radio, etc), you observe more of the low-level background. Static, hiss, and so on. In a picture, this shows up as "noise" in the details of the image, and will typically result in pictures with more of the oil-painting look.
The lens on the G4 is f1.8, and should let in more light than the iPhone 6, at f2.2. It's certainly possible the iPhone does better noise reduction, or things along those lines. I'm not saying the G4's camera is perfect. But it shouldn't be woefully worse in low-light, anyways.
To get a comparison of how ISO affects things, try taking the same, stationary-subject picture, at maybe ISO 200, ISO 800, and ISO 2000. Then zoom in and look at the details of each picture. BTW, every camera will exhibit this behavior.

it has nothing to do with the cache and stuff lol they sound stupid. just play with the settings. i typically use my outdoor iso from 100-500 depending on what kind of lighting or colors are present. for indoors i set it 500+. just don't go within the thousands if there's no vivid colors or bright lights. try like 500-800 for the iso and 1-1/8 for the shutter.

"do you mean just the jerky image if you move the camera around? "
Yup. I hate the jerkiness but I guess there's no way to work around that other than decreasing shutter speed and increasing ISO which results in super grainy pics.
I will try the flash light and see if its any better. Usually, I dislike using flash in normally lit indoor places. It doesn't feel natural.

Just run into this older post.
My two cents: to avoid high iso muddiness in indoor lower light portraits, you should turn on the flash (or better, use an external led panel to create off camera light)
Indeed flash photos are unappealing, but you can improve them with Snapseed's selective editing, by lowering exposure and warming temperature on your subject faces.
You could also selectively increase exposure on one side to create a less flat picture.

Hey guys,
I am having trouble taking good pictures with indoor lighting. The first problem is that the viewfinder (or the image on the screen) is not very smooth. It's jittery and lags and its super annoying. How can I improve the speed of the viewfinder so I can frame shots better?
I also hear that the LG has fantastic low light capability. However, with indoor lighting (fluorescent bulbs) I find the images have a lot of noise and the details appear very muddy and very oil painting-ish.
I don't have any problems during sunlight but indoors, the G4's camera is a mess. It's slow, jiterry and all round annoying to use. Any help would be appreciated!

I am a photographer and am trying to change over to the new mobile camera trend that started years ago but I do know that with LG, since my friend has one, doesn't have a good sense of lighting, period. I am not trying to put down your device, I do not think you need a new one. A good artist can make art from anything and everything to their best of the ability with what they have. I think you should start trying to do things like opening blinds to a window, putting white sheets of paper around or maybe some gray or black sheets of paper to balance your lighting. Is it at all possible for you to share a visual load of what you're doing with the community? I think it would be valuable to have multiple sets of eyes and have many different minds working with you to solve your problem.
