I just suspected, HDR mode in camera app that it is a new technology in the hardware or just to take pictures and then adjust the picture brightness to brighten it up which others app it can be done.
It actually takes 3 quick pictures: one is properly exposed (well according to the software), one is over exposed, and one is underexposed. The 3 images are blended together to make one with more dynamic range than just a single photo from this camera can provide.

That is what a normal HDR mode is supposed to do. But then Google's HDR+ in the Nexus 5 isn't a normal HDR mode.

It is simulated HDR. True HDR shots are taken by bracketing the exposure (shutter speed) of an SLR camera (part time photographer here). A cheap little image sensor in a phone can't do this, so it simulates over exposure and under exposure by taking a longer or faster shot from the sensor. Then the camera software automatically combines the images. In a true HDR photo, you need some decent software to merge the bracketed images together, and this usually takes time to tweak everything by hand to make it not looks like ass (see /r/****tyhdr for plenty of examples on how NOT to do this).
Anything claiming to be HDR that is not taken from proper bracketing on an SLR camera is basically simulated HDR.

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.
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.

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.
Hi, I'm interested in using third-party camera applications.
I seek above all the following:
It works on Nexus 7.1.1 without rooting.
Record to slow camera videos
HDR of the best quality (for now the Samsung has seemed the best because I do not change the color of the photo too much, the HDR + colors a lot and there are comic photos)
I have already tried the typical Open Camera-Fv-5 DSLR Camera- Bacon Camera .... and they do not give me what I am looking for
Thank you
Camera Zoom FX Premium. It has the best HDR of the third party cameras I've tried due to it using exposure bracketing to create the shot. The exposure bracketing however means the camera is slow in taking a shot, because it has to take three shots and merge them together in software in order to create the image. This also means that moving objects in a HDR image may create ghost images.
HDR+ in the Nexus devices that support it I feel is a better option than even Camera Zoom FX Premium's HDR. HDR+ isn't perfect. It takes a shot quickly but has to spend time compositing the final image, due to how HDR+ works. It does however eliminate the problem of moving objects in a shot. This is because unlike the exposure bracketing of HDR, HDR+ brackets using film speed (ISO). The reason for the amount of time spent compositing the image is due to HDR+ taking ten images with one press of the on-screen button.
I had bought it, but I did not think it was very practical, right now I use Fv-5 and Google camera.
I really like the samsung camera application, because it does not distort the actual color of the photo,
And I do not need to do several photos to have an hdr by software. But I do not find anything similar in third-party applications.
Is there no port of the LG, Samsung, HTC camera that works on a nexus 6?
I'm not aware of any ports of those camera apps. As to the Samsung camera, it uses software to create an HDR effect. Software-based HDR by its very nature distorts the color as the HDR effect is applied to the image. As a result software-based HDR is always going to be inferior to hardware-based HDR solutions.
True, but it is difficult to do 3 photos in a row, without tripod, and many times there will be people, which will result in ghosts.
Which is why HDR+ is better than exposure bracketing HDR. I do believe I said as much in a previous post.
I don't get hdr is a separate mode and just not on by default for taking regular pictures? Wouldn't you want hdr on most of the time?

Hi worldsoutro,
Photography is all about capturing light. And HDR is just another way of doing it. But it's not main way of taking photos. So, it totally makes sense to have HDR as an option. HDR stands for High Dynamic Range, which in return allows you to combine whites (bright spots) and blacks (shadows) in one image. In order to create such image, the camera has to capture at least three images.
1st - under-exposed (this image will give you very nice and dark shadows).
2nd - correct exposure (normal photo).
3rd - over-exposed (capturing those whites, sunlight, anything bright).
Then software will take all three shots and compose one image. The three images is a bare minimum, and there are methods that use 7 or more images to combine into one.
The biggest downside of HDR is color representation. All colors are going to be in extreme ranges. Also taking HDR photos is probably heavy on the battery, since you are probably capturing more than one image very quickly and processing it (HDR in Huawei might all be simulated via software as well, so it might be just taking one image and processes it to make it look like HDR).
If someone has info about how Huawei has implemented HDR photography, please post! I'm actually curious now.

Your description of combining exposures is correct, but you got the reasons for the different exposures wrong, underexposed is to retain detail in highlights, and overexposed is to retain detail in the shadows.

So in a bright sunny day should I always shoot with HDR?
Good catch guys. Yeah, overexposure allows you to get all details in the shaded areas and preserve them. While underexposed photo would exaggerate light sources.
I suppose we are turning this into HDR topic altogether.
worldsoutro - I think you can use HDR whenever you think you will like the result. Photography is art in the end. I would say that during midday hours (when the sun light is the harshest) and at night (with appropriate light) HDR can give you some cool results.
Play around with different modes. Check out Pro mode too. You basically have a full control over the scene. It's pretty cool.
Hope it all was helpful. Cheers!
Auto (photo) mode uses HDR whenever it deems it appropriate - it's those situations where it says "sharpening - hold the device still" (also the same situations where most of the criticisms of excessive sharpening apply).
It's a less elegant implementation of the auto HDR you see in some other phones, and one you can't turn off without switching to pro mode (but then pro mode is very good on the P20 Pro and also allows all its settings to remain on auto, so usually not a big problem making that switch when you need it).

It depends on what outcome you have in mind the time you take the photo. I like playing with light and although I like wide dynamic range look, I also like to take photos with high contrast, so auto mode gets played some times and I have to lock the exposure the way I want
I am using dslrs for many many years (always travelling with a backpack full of lenses) but I think this phone's camera is really amazing. In really low light situations you can take way sharper photos than what you would with a dslr when handheld, and that's something.
