Which resolution is best for photos/videos? - Nexus 6 Q&A, Help & Troubleshooting

According to "OpenCamera" I am using a 4160x3120 resolution when taking pictures.
This isnt a wide-screen resolution and I wonder if that makes any difference quality wise? Can I just stick to this resolution or should I go for a 16:9 reaolution (4160x2130) ?
Thanks !

Wide screen mode on the camera is the equivalent of taking a 4:3 image and cropping it in Adobe Photoshop. The image has fewer pixels after cropping, which is why the stock camera and some other camera apps make a big deal of pointing out the resolution at each setting. You don't lose anything in terms of quality as you are taking the image with a 13MP sensor. The software simply discards the unused data.
The setting is a matter of personal preference. I keep mine on wide screen despite the data loss because I like it. If you like it, set it and snap away. Otherwise stick with 4:3.

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:

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:

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:

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.

camera - Picture size question

There are so many options available.. any quick reference on which is most optimum? I don't mind the biggest resolution/ size. I "plan" to backup my photos regularly. What do you all use?
16:9 All the time
4:3 offers the widest and top resolution. Form there you can crop to 16:9 or anything you desire.
16:9 cuts off the top and bottom of the sensor...
I use the highest resolution as well. If need other form factor can crop.

Camera aspect ratio

Hi guys,
To my surprise, my brand new P30 Pro camera's app doesn't come with 16:9 aspect ratio resolution which is a shame...
My old Mate 10 Pro had it and I can't see myself watching my picutres with those 2 white squares on the left and right of my pictures...
Let me link you an official thread about this issue: https://uk.community.huawei.com/mate-20-series-20/who-would-like-the-option-to-take-16-9-aspect-ratio-photos-with-your-huawei-phone-1520
For me, it's a bummer...
If any of you is able to "mod" the app to get back that 16:9 aspect ratio with high resolution, please advise ! Or any kind of contact to Huawei cuz this doesn't look THAT complicated to add back..
Regards
Yea, that would be awesome to have this. A phone this expensive doesn't have this crucial aspect ratio? How come? Don't people watch photos on tvs or monitors? 16:9 should be the standard for casual photographers.
It still has a full screen photo mode, but you have to lower the photo megapixels from 10 megapixels to (full screen) 6

Full screen is 19.5:6 aspect ratio, which is far too wide. The point is to view the photos on TV or monitor in full screen. This aspect ratio is rather useless, it crops too much. The camera is nice, but if I knew it doesn't have 16:9, I'm not sure if I would buy this phone. Now it's too late, already bought, and I'll have to spend a lot of time to crop thousands of photos I'm doing on my trips.
Also the default gallery application in which I can crop the photos has a bug - if I do a 4:3 photo in 40 megapixels and crop it to 16:9 in the default gallery application, it changes the photo resolution to 3648x2050 from 7296x5472, so I need to use some external app for that.
So if anyone is reading this:
DO NOT CROP THE PHOTOS WITH DEFAULT APPLICATION

if you mean this one:
getdroidtips.com/download-google-camera-for-huawei-p30-pro/
I tried it. Sure it makes the photos, but it has lots of issues:
1. Camera switching doesn't work, I can only use the main camera. No wideangle, no tele
2. After zooming in the app crashes
3. Max mp I can get in 16:9 mode is 8.3, not 29.9
4. No portrait mode and lots of other modes from stock application are also missing.
So sure, I can do photos with 16:9, but what's the point if I can't use most of options that hardware provides? Cropping for hours or days after making thousands of photos is still the only option here.
There is not good solution, which is really sad.
And if you mean an app for cropping, I already found a better one - Simple Gallery and PicTools for cropping in bulk.

Faced this on my Huawei and I feel really frustrated!

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.

MI 9t Pro, Camera settings.

So Xiaomi, appears to have made a, rather strange, decision, to remove resolution settings from the standard camera app.
All you have now are quality settings: low, standard and High.
now, default is High.. I dont really need my images in full resolution in 90% of the shots I take.. They are most often for MMS or other image sharing things, and they take up quite a bit of space and often need to be scaled down manually.
Does anyone know, if the Quality settings, mess with other camera features/settings apart from resolution.. ? I would like my images to be smaller (both scale and storage wise) but I would rather not loose a lot of image quality..
Thanks in advance.
try with gccam porting the resolution is very high i don't Know because xiaomi have this bad setting on stock camera
