Hello mates! I've had mi G6 for around 3 weeks and I love it. But the wide angle camera does some strange fish eye efect on the borders of it.
I uploaded one with the regular mode and another with the wide angle mode to make a comparison of both.
What do you suggest? Talk with the sellers?
Thx in advance.

That means that it is a normal behavior?
Yeah its normal
Haha yeah. That's how it works.
If you take a picture of a big panorama or something, you'll see it looks much better.
That's why the normal camera is used for up close normal photography.
Yeah.... wide angle lenses will have barrel distortion... that fish-eye effect... There is really not much you can do about it. Think about it, when it's taking that pic, the image it sees isn't 'flat', it's looking at a large arc, a 120-degree arc, then projecting what is essentially a curved image onto the flat sensor in the camera. Every wide angle camera lens will do this, and the wider the angle, the greater the distortion.
Now, your eye has a larger field of view, why don't we see the same distortion? Well, ignoring the fact that the human brain is one of the most powerful image processing engines in existence and will compensate for a LOT of junk, your eye's sensor, your retina, is also curved.
There are some tools you can use in photo editing applications that can reduce the distortion, and they stretch out the corners. Now, if you took that wide angle photo and then projected it on the inside of a sphere, you wouldn't see any distortion.
The main camera sensor is also distorted, but it's a much more narrow field of view, so the distortion is not nearly as prominent. But if you look at the margins of the pictures you take, you will still see some of that distortion.

I searched for a camera fix for the HD camera with no success. Does anyone know if there's going to be a fix in the near future? I'm sure that ya'll have the same problem that I do. Camera takes pictures that look old & rustic. Brownish tint to them & not very sharp for a 5 MP camera. I have adjusted all the settings for light & junk but nothing fixes it. As far as I'm concerned, it should take pictures IDENTICAL to a normal 5 MP digital camera. I can promise you that it's not doing that. Any help would be great, thanks in advance.

Why should it take pictures identical to a 5MP camera. The lens on the front is going to be vastly different, the sensor maybe 5MP, but what is the spacing on the sensor pixels? The closer together, the noisier the image. Colour balance will be down to the sensor too.
Regards
I'm not talking about the front camera. The normal camera on the back. I understand about the pixel thing, but it still shouldn't be so brownish, right? The pictures look like an old Polaroid picture. You know, the one's that spit the picture out as soon as you took it. Old, brown & nasty looking.
My pictures come out fine...
Hmmmmmmm...................... I'll just keep playing with it.

I'm not being flippant, but is it possible you might have a dirty lens?
Lol, that was the first thing I tried. Cleaned both sides of the back cover & cleaned the lens on the camera. Good idea, though.
The "5mp" doesn't really mean much, as stated earlier, if the sensor and lens are poor quality. As far as I know, HTC haven't released a phone with a reasonable quality camera, yet.
I bounce between different smart-phones (just coming back to WM now, after a year with S60). I can say that many of the S60 devices (in particular the Nokia N95, but also the N82 with Xenon flash) have very good cameras, being similar to low-end digital cameras in daylight. They lack optical zoom and tend to over-compress images, but have good quality lenses.
imho hd camera is excelent
pictures look old & rustic only if you make them inside house without using the artificial light setting, and this is also a general rule, not specific to HD.
Never seen a good phone camera yet, including the latest 8mpixel ones. They're all terrible.
Never
This camera will NEVER take pictures anywhere near what real cameras do. The photo sites are so tiny, they are smaller then the length of waive of light. Therefore noise, lack of dynamic width, etc. No patch will ever fix that. Sorry
open back cover , clean the lens , you will see a huge difference in quality

Not that I'm doubting you or anything but you do realize that the back cover only has a hole through to the lens?
You might try setting the brightness higher:
If you touch the small rectangle near the bottom right side of the screen (when holding landscape)
Then select the gear symbol, then select brightness from the menu and hit the "+" until it looks better that will remove most of the darkness.
The camera is a plain disappointment. In the time the camera autofocusses, I could have bought a Sony Ericsson C905's, create a good looking photo (with xenon flash) and upload it to imageshack.
If 'your object' makes the slightest move, your photo will be blurry . This is also the case when you attempt to make a photo of someone that isn't aware he or she has to be waiting for the autofocus lag. Head moves >>> blurry pic.
iPhone camera shots are way better quality, don't ask me why. Overall my Touch HD scores 8/10, where atleast 1 full point is taken up by the camera
and it's better don't speak about the very laggy video recording

Too many megapixels on a tiny sensor = major noise problem = blurring from denoise.
Even 2mpixels is too much for sensors this size, but people buy on marketing numbers of megapixels, not quality. You can just imagine the whining that would occur if the Touch HD came out with 1.3mpxiels, even though it would produce better pictures.

hehe, thats true.
mpixels dont count as much as the general public belives. the more mpix. the higher rezolution you can print the picture in. but for ordinary photos, 1.3 mpix would be enough, as long as the optics is good.
Personally, I rarely use a phone camera.
I use either my Olympus 720SW or Canon EOS.
the camera sucks **** compared to the n95 and the video recording is horrid. i know it's not meant to be as good as a dedicated camera but this is pretty bad given the price of the device.
i concur with mach03, move the camera a slight bit and eveyrthing gets blurred. one way i've semi gotten aorund this is to unlock the burst functiona nd take a sequence of pics and hope one or two coems out alright, not the most economic way to do it though...
i would ahve thought that maybe there's a way to tweak the camera to stop the blurring or even affect how much light is picked up by the lens which should also help with clarity

A silly idea, but seriously, did you check if maybe, just maybe, you left the "sepia" effect turned on???
I took a couple of videos and the quality to me just isn't that great. This is with the UHD setting. Just isn't that clear for UHD.
I agree I had lots of noise/grain in mine. FHD60 seems a bit cleaner
This is a pic zoomed in half way. Looks awful. I bought this phone because the camera was supposed to be unreal. Is this normal or just maybe I have a bad cam?
Shot some video in a dark bar venue of a band playing. Using the main lens and manual settings, it turned out really well. The wide angle left a bit to be desired as shot but I think I have an idea for that lens. Shot with 1080 at 30fps high bit rate. Posted it in another thread over the weekend.
And at full zoom
Shot at 1080 30...

Looks as though you may have a dirty lens.
The light in the room is a give away of grease or finger prints across lens. As the ceiling light starts to chase across your shot.
Same thing can cause grainy pictures. As it effects even a camera shot the same way.
Always try cleaning the lens if the shot seems to be poor.

I've tried to clean the lens, no luck. Do u think it's the phone itself?
Did you set to record in high bit rate?
Personally, I think the camera, both video and still, is the weakest part of the phone. I am not happy with that, but will live with it until the Note 8 comes out.
And you removed protector of the camera lens?

What other settings did you use? (ISO, Shutter Speed, Bit Rate, Filters?)
I will say that it looks like you're using the digital zoom, which is always problem #1. Never use digital zoom unless you have to do so. Whoever came up with this gimmick should be dragged out into the street and hung. It just doesn't get you anything but a mess. Optical zoom is optimal. Bipedal zoom is your secondary option. Digital zoom just shouldn't be an option. It is quite literally the option you choose when you want to have some sort of shot, any shot, and you don't care about the quality of the shot. This goes for any device from a cellphone up to a DSLR.
---------- Post added at 12:32 PM ---------- Previous post was at 12:21 PM ----------
This was shot in a very dark bar venue with mediocre stage lighting. (Strike one against getting decent footage.) ISO 3200 (Another strike against any decent footage as you're maxing out the gain on the sensor.) 1080 at 30fps so I used a shutter speed of 1/60. I used the high bit rate setting. The refocusing is me touching the screen as I couldn't tell if I had good focus since it was dark and my eyes kinda suck these days without readers. I was playing with the audio settings and had no idea how to set it for a concert so I cheated and used approximately what I found for concert settings in the HD recorder app.
Considering the conditions..... the V20 did extremely well! I could pick things out in the audio that I couldn't live in person. In person, it was just a wall of sound sometimes. The video turned out amazing for being a tiny camera sensor. The only real thing I can knock the V20 on is the video stabilization. There needs to be settings somewhere so I can turn the OIS and EIS off and on so I know if it is on or off.
Are you using the stock cam app? I don't see anything where I can change the zoom type.

Yup, stock camera app. There is no setting for changing the zoom type. If you aren't clicking the one tree/three tree buttons, then you are going through a digital zoom. Only clicking those two buttons uses purely "optical zoom" although in reality, you're just completely switching cameras. (Different sensors and different lenses which presents its own issues since the wider view uses a smaller sensor and smaller aperture while the main shooter uses a "larger" sensor and larger aperture.)
Using pinch to zoom or the zoom slider means you're going through digital zoom. So if you start at the widest setting with the wide view and start zooming, the image quality is only going to get worse until you pop over into the main imaging group. Then if you continue to zoom, the image quality will degrade again. The best quality you're ever going to get out of any single focal length imaging assembly (which is what we're technically dealing with here, two single focal length imaging assemblies) is at its native focal magnification and at its base ISO. Which the photo options says is 50 but that's not always necessarily true, I'd have to look up the native sensor ISO online to be sure.
Did an unprocessed and processed test with my v20. By far the best dynamic range of any phone camera I've worked with.

The only positive thing I found about the digital zoom on the v20 which is unique in my experience is that when you're shooting 1080p on other phones, even though it's a 4k sensor it zooms up on the post sampled 1080p frame instead of taking advantage of the 4k sensor and zooming up without any quality loss. The V20 appears to do just that and up to a point there's no fidelity loss with the digital zoom because you're sampling a smaller section of the sensor..

Did you gain any insight to help fix your grainy pic issues? I'm having the same problem. I keep seeing people suggest to remove the plastic protector but it has cutouts for the lenses and the sensors so I don't see how that makes a difference. I'm taking pictures without any zooming but when I take a look at the results and zoom in to different parts to review, it looks horrible and grainy.

I haven't. I wouldnt take the plastic off. As you said, it has cutouts for the lens. Not impressed at all with the camera
I'm amazed at your low light video. I also thought the camera was the weak point of the phone. Guess I need to work on my manual focus skills.

Hi all - it sounds like the front (selfie) camera does not take the best pics.
One of the uses I wanted for the G6 is to use the back camera (the wide angle one) to take selfies instead.
I won't be able to see the screen, but with the wide angle lens, I don't really need to do much framing I'm guessing.
The only thing that I'm concerned about is the lack of auto focus and if the wide angle camera can focus on subjects about 1 metre away from them.
Does anyone have a G6 who could comment / or post a sample pic of this? This is pretty much the dealbreaker for me to get this phone.
Cheers!
I'm interested in the same question! Would be great if anyone could comment on this, hence bumping this thread.
Yes. Front facing camera is not as good as it should be. Specially in low light situation...
This, and lack of LED notification light are the biggest flaw to me
Back cameras takes good selfies though. I don't have any problem with framing or autofocus. Does a good job with defocusing background and shaking effect is at minimum thanks to new image stabilizing system.
Hope this help you
Cheers
Someone here at xda calculated that all things between 35cm and infinity are in Focus for the wide angle camera.
I also made some tests and I think that he is not totaly wrong with his 35cm.
So taking selfies should be ok.
hey guys
I have seen this problem in my xc rear camera photos and also in one my friends' xc, so I was wondering if there is a fix or if it is hardware issue or software related,
photos taken by rear camera seem to stretch the sides of the picture and also are a little blurry in sides
for example if you take a picture of a bunch of people standing next to each other, you notice that faces in the sides of the picture are a little stretched and not in real size!!!

I have noticed the same thing. In portrait photos too the heads look stretched vertically. Not happy at all. I'm going to be selling this phone. To be honest my old Xperia Z took better portrait photos than this one.
This is mostly due to the optics of such a small image sensor and super small flat plane lens atop the camera. Anytime the focal length and the lens curvature are not perfect you get some blurring, and they are only perfect at a single point in any camera systems range of focus.
The stretching of the sides is due to the super short focal length/wide angle lens. Same issue happens if you stick a 14mm close up/fisheye lens on a slr camera. This portion of the problem is often corrected for in higher end cameras with software, Sony recently pushed an update to other xperia phones with the same or similar camera to run the algorithm to correct the un-equal representation.
Compounding the issue :
Smaller flat plane optics cause a lot of chromatic abortion as you radiate out, it's the worst in the corners. This gives it a vignette style are of focus and is just not avoidable either.
Sony made the choice to do a lot of image smoothing to hide their noisy camera and it also happens to hide the abortion as a blur effect. I'd rather have the abortion personally than loosing details in a blur.
The highlighted thing about g5 plus was also the reason for bad camera. The 1.7 aperture and wide angle camera are the cause here. Though it is good for shots within a certain distance like 10-15 feet. But any further the pictures loose sharpness and gets noisy due to which moto decided to use high denoising due to which the photos look soft. My father's redmi 4 clicks better distance pictures than this. It has 2.0 aperture and little less wide angle lens.
Don't forget that G5 Plus have the same camera sensor as HTC U11 or Asus Zenfone 4 (which takes good pictures on stock software).
Worse photo quality is caused by software (Motorola/Lenovo screw it up).
Did you tried any mods/apps? You can find a lot of these, but I suggest you to try Google camera app port.

I use bacon camera on stock Android without root.
I disabled noise reduction and use hdr with manual mode and stable hands to get though grainy but nice pictures. Though the app is not perfect but it works
When I first got the G5+ I thought the camera was too dark... While a lower aperture may help in low light shots it does cause a bit of trouble for highly illuminated scenes.
HDR does compensate but it's nothing like HDR+ from Google.
Plus, terrible sharpen and overdone Noise Reduction excessive Color NR.
I felt quite dissapointed comparing it to my old Titan (G2)
Anyone tried to mod the camera to enable debug mode? You can disable noise reduction from there

Coming from an old school enthusiast of photography background - you're aperture on your lens (in this case f1.7) isn't going to cause noise - that's a function of the sensor. A lot changed when we went from film to digital sensors, but the impact of the f number of the lens did not.
You might be on to something with the with loss of sharpness though. Typically a fixed focal length lens is at it's sharpest at it's only setting... but they very well could have forked this up.
Given that the camera does pretty adequately with other camera software or other hacks - I don't think it's a hardware issue or lens issue. It could be a cut rate sensor...
It could also just be that whomever chose the default settings for this camera did a bad job

What about shadows in bright scenes such as outdoor scenery?
I mean, wouldn't lens aperture like f2.2 preserve more of these details?
That's a function of the film/sensor.
Your f number controls light and the depth of field (area that's in focus) - a smaller f number is more desirable because it allows more light to the film/sensor.
The only thing different here than fine that I can see is the size/diameter of the lens related to the f number. A larger f number, like f 8 or f16 increases the depth of field and sharpness, but at the cost of light hitting the film/sensor. That results in a longer exposure time.
A wide open f stop means more light and shorter exposure times.
One thing we gained with sensors over film is a wider range between highlights and shadows... You could get more shadows and more highlights. Film could get only so much of that before shadows went black and highlights blew out to white. But you still have a limited range. You can't get it all. In order to keep the highlights from going completely white you have to trade off some of the shadow range.
It's early and I'm probably explaining this horribly. Your spectrum between black and white or shadows and highlights is very long. But your camera sensors capability can only encompass a range of that spectrum. If the spectrum were a line of shades of grey from black to white that was, say, 10 units long, the range you could get in one image might be six units long. You've gotta give up somcombo of four units either at the black end of the spectrum or the light side.
If the cameras loaing details in the shadows that's because it's opting to the highlight/light end of the range.
So lens doesn't play a huge role in what chunk of the spectrum the film/sensor can encompass. But does play a role in how quickly the sensor can collect that info. Higher f number = smaller amounts of light on the sensor = longer exposure times.
My guess would be that the sensor or software is biased toward highlights because it results in faster exposures making life easier for snap shots and selfies.
