Just suspected about HDR mode - Nexus 5 General

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.

[PHOTOS] ISOCELL camera discussion - my review is up!

We discuss ISOCELL camera technology and new camera features, photos shared on the internet, and Your user photos and videos here.
Features of the Galaxy S5 ISOCELL camera unit:
15.87 MP (5312x2988) 16:9 aspect ratio Samsung BSI ISOCELL sensor
PDAF (phase detection auto focus) for fast auto focus
4k video recording, [email protected]
Live HDR phoro and video preview (Rich Tone available for video)
Software image stabilization
Selective focus
Drama mode
I got my hands on the S5 thx to the guys at XXL GSM, so here's my review:
Since smartphones took over compact cameras as the most popular tool for daily photography, each manufacturer is trying to create it's own camera tech. Sony put the metal wiring behind photo diodes to capture more photons (BSI), HTC introduced the large UltraPixels, and Nokia came up with the large sensor 41MP PureView tech with OIS. Samsung only slightly adjusted it's sensor size (1/2.6") and pixel count (16MP with 1.12um sensor pixels) for it's 5th Galaxy S phone, but with a new sensor manufacturing method, they are introducing higher dynamic range and better color reproduction, in what they call "3D-Backside Illuminated Pixel with Front-Side Deep-Trench Isolation (F-DTI) and Vertical Transfer Gate", or because they're physically isolating pixels to decrease light crosstalk, "ISOCELL". For faster focus they also added a phase detection auto-focus layer (PDAF) delivering ~0.3s focal speed, plus image processing capable of live HDR and HDR video recording. Add sensor-level digital zoom in video, meaning you don't zoom into the 1080p picture anymore but use all the 16MPs, and the S5s new 16:9 sensor delivers a much needed step-up in camera technology.
In good light conditions the S5 rivals any rival phone in snappiness, white balance, color gamut and focal accuracy, also offering healthy amounts of details for print quality images. HDR works seamlessly and sometimes you can't tell it was on, only you realize little to no detail is lost to clipping, it works darn fast too, albeit with some loss of details. Facing directly into sunlight, and dynamic range stays solid without lens issues, color errors or aberrations, and noise levels are kept at a minimal. Jpg compression is slightly above ideal as seen in the smallest details, on the other hand, speeds are excellent, tap-to-focus and tap-to-shot is almost instantaneous, and the app opens and finishes the first shot from cache in about 1.5s, 2,5s from a locked screen. The S5 can take about 7 shots per second in a photo burst (long tap on the photo icon).

In lower light conditions, as most small sensor smartphones, the S5 is a mixed bag, but an improvement in color reproduction, focal accuracy and snappiness over the S4. Missing are the optical image stabilization (OIS) and longer than 1/17s exposure times (Camera Zoom FX can do 1/10). The Photography app ranges from ISO40 to the very soft ISO2000 shots with manual setup available between ISO100 and ISO800 (Zoom FX does ISO1600 too). In dark conditions, if LED flash not used, you can turn on image stabilization (former night mode) to battle noise, and a multi-exposure of about 3-4 seconds (hold the phone steady) compiles an improved low-light image. HDR works too (with more noise on the sides), and while movement requires stability turned off with higher ISO or flash, optionally Sport Mode, overall I like the accurate color reproduction, which is a problem for many rivals. My biggest criticism besides OIS is the lack of 1/5 1/2 1s and other longer exposure times and manual control for it, at ISO100 with a 1 second exposure the ISOCELL sensor could capture much more details, and since the Lumias have OIS, they are better than the S5 in this category.

Besides setting up ISO, exposure, white balance, resolutions, timer, voice control etc. from the menu, there are Samsung's various camera MODEs. Selective Focus shoots multiple focal shots of the same subject, and you can later select the preferred focal point - foreground, background or both - algorithm is not perfect. In Shot and more the camera takes a series of images before a fixed background, and allows you to choose Best photo, Best face, Drama mode to record multiple phases of a movement on one image, delete unwanted stuff with Eraser and add motion blur via Panning shot. The Shot and more editing menu comes up after taking the shot, later you can access it from the Studio.
Beauty face lets you play around with skin tones and stuff, Virtual tour is like moving around in Street View: you turn and walk around taking several shots in a house for example, and later revisit it virtually moving around with arrows. Dual shot places both camera images on a single shot, Animated photo creates a gif, Sound and shoot allows you to add a voice comment to your shot and Sport mode uses high ISO and wide focus not to miss any fast movement, have this one on with kids around. There are two Panorama modes, regular 2D one with horizontal movement, and the Nexus-like Surround shot that does 3D photosphere, with some inconsistency. Trick for a good sphere is to hold the camera lens at the same spot and move the phone/yourself around it.

The Samsung Gallery is quite advanced app, you get several views of you single images, folders and multi-folders with previews, and Air View helps checking content without tapping on it, hovering over with your fingers. Studio gives you a whole lot of options for editing, besides Photoshop-like functions and manipulations, you can make photo montages, trim videos, render slideshows and edit Shot and more mode photos.
Video recording is a great joy on the S5. Sound is clear (though I made the mistake of covering one of the stereo mics due to hand stabilization), software stabilization is quite usable and HDR is good, as well as recording in 60fps for smooth motion, though these are limited to 1080p resolution maximum. There's fast motion up to 8x and slow motion recording down to 1/8 speed without sound, but the real gem is recording the the marvelous 3840x2160 or 4k resolution, which is 4 times the pixel count of 1080p. Eventually we'll get 4k TVs and monitors, heck, tablets and phones come out with 2k/4MP displays nowadays which is almost there, so why not record in 4k right now? Just check the frame captures I posted below to see the details and low level of mp4 compression, you could print some of these frames. The trade-off is the lack of HDR, stabilization and 60FPS at this resolution, and a 5 minute clip limit since each 60 seconds recorded at 47MBit/s takes up around 350MBs. Yeah... In lower light you obviously lose some of the gorgeous details and noise comes up, but it's still quite nice.

Conclusion
Overall the S5 camera is highly satisfying in this reviewer's option. I did not find a single case when white balance, saturation or exposure was off, operation is fast unless you have stability mode on in low-light, focus and dynamic range definitely improved, and you can choose among many video and photo options. Where's the biggest step forward? In consistency. Out of 10 shots you'll get good ones at a far better rate than before.
Obviously low light is the S5's weaker point, with less light you get softer images and need flash or high ISO to capture movement, but where you lose details to some rivals, you gain color accuracy, so Samsung's ISOCELL is getting there. Next stop should be OIS, but one thing they could do right now: allowing longer than 1/17s exposure times so we can set low ISO value and capture more dark details. Maybe the future Google camera API will open this option. Overall however, I think the shots speak for themselves: the S5 is a very capable shooter with some room for improvement, and you'll be able to pull many print-ready shots over your long usage. Just be aware: as good as the S5 battery is, things like 100% screen brightness and 4k recording kills the 2800mAh quite quickly, bring a spare battery or power bank.

Tips and tricks
- Do multiple shots of the same subject, a good momentum or less handshake can later be selected out of the many
- HDR is one tap away, so do one with and without it, some shots look better with high contrast, others benefit from HDR
- In low light with movement, you have to use LED flash without stability, cause high ISO and longer shutter will not capture these moments with good detail
- In low light with stationary subject however, use stability, optionally LED, no HDR cause of noise. With enough lights you may try using ISO800 with darker results but more details. Much will depend on the amount of available light
- use voice commands to avoid tap-shake, hold the phone steady with two hands, optionally use a monopod
- try and use the photo Modes, some will do fancy images, others come handy like Sport mode to capture fast movement
- between Panorama and Surround Shot, I prefer the latter, cause it captures surroundings vertically too, so result won't be an overly wide image. The trick with photospheres is to not be close to the surrounding objects and have the camera lens in the absolute middle in space, and move the phone and yourself around that spot as the take the sphere images
- try alternative apps if they are better for you: CameraZoom FX, Focal, Google Camera etc. Camera Zoom FX allows 1/10 exposure and ISO1600 manually
- be aware not to cover the top and bottom microphones during video shoot. Best image quality comes from 4k, but image stabilization, 60FPS or HDR only works with 1080p, again best to test all these and later use the one best suited for you or the scene
- use AirView in Gallery, and try out Studio options for your recordings
- bring a power bank with longer photography tours cause a lot of camera usage and 100% brightness eats the battery quickly
Let's analyze! The first two striking qualities of the ISOCELL samples are: 1) eye popping wide dynamic range with rich colors, and 2) relative high noise and softness of the picture. I guess that's the tradeoff here.
Saturation is quite high yet not unrealistic, it simply looks to capture a wide color range, especially impressive in the Angry Birds photo inside. White balance is spot on. As far as Rich Tone (HDR) shots goes, it's pretty impressive as well, look how much more detail is presented without overprocessing the image. On the other hand, noise and softness is always present on these shots, even at low ISO, PureView and Exmor technology seems well ahead in per pixel sharpness. More to come.

Yup. :good:
BTW, it appears that selective focus takes 4 photos or at least renders 4 photos, as samples played around with that setting have ~16MB size instead of the regular 4. So I guess the file can be shared and focus changed afterwards, wouldn't mind Google+ and other services allowing you to choose focus after upload.

but why you delete all info? including EXIF.. It's not secret
Again its not isocell ( probably they saving it for Note 4 or GS6 )
no new flash ( same old led flash )
indoors photos still look like oil paint -->> no OIS indoors and low light images will suck
overall i think it will be like most of Galaxy flagships : great images when there is enough light but when there is not the image will suck
I think it is ISOCELL technology, the photos on PhoneArena are really not bad at and higher 5s z1.

They just started mass production for the 16MP ISOCELL sensor.

The article also mentions the new octa for the octa variant for the S5, also beginning mass production.
Samsung doesn't mention specific hardware specs anymore.

Because Samsung never EVER goes technical about sensor tech, check their track record, they don't.
It is a vastly different sensor to the Exmors however, closer to Samsung own's Galaxy Cameras (softness of image, noise), but far superior in color balance and dynamic range, which is exactly what ISOCELL is all about. Add that announcers did show off new camera HW features and Android Authority claims ISOCELL was confirmed to them, so it's almost certainly that tech.
So where do you get your information that it isn't?

All right, new stills from GSM Arena, normal vs. rich tone (HDR), direct linking so EXIF info should be included. Level of details don't justify 16MPs, but color reproduction and HDR quality is quite awesome!

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.

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)

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.

APPS Cameras from other brands for Nexus 6? Slow Motion and HDR

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.

Why is hdr a separate camera mode?

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?

Because they wanted to appeal to photographers and HDR is a dirty word.

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.

Over-exposure gives usable shadows and under-exposure usable highlights [emoji16]

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.

No burst and time-lapse photo mode?

Why is there no burst or time-lapse photo mode?
Time-lapse workaround: The app Intervalometer hijacks the stock camera app and simulates touching the shutter buttons, so you get a programmable time-lapse in all modes, Raw, Night-mode, all the 3 cameras. Probably better than Huawei could ever make it.
As for burst mode: its there if you set the resolution to 10MP or lower, no burst mode for 40MP or with raw files.
Time lapse mode can be found on the last page of the camera options where slow motion , monochrome , moving picture is. To take pictures in burst mode you just press the camera button and it will take pictures in burst mode untill you release it.

No that's a crappy low-res time-lapse video, I'm talking about photos.
Found the burst mode though it has its limitations, that aren't mentioned (how should the user know). They only work in Photo Mode and only if you set the resolution to 10MP or less.

Go in play store, ans download Framelaps application. It is very good. You have so much options. It is taking photos and you can make 4K video, not 720p like in original camera application. Too bad for Huawei that's is not so hard to do.
Only bad thing with Framelaps you cant you Suoer Wide Angle.
Probably can't do a lot of things, like the correct colors for the new sensor. And yes, kind of want that for the ultra wide.

Yes I know but it helps more the p30 pro software camera (stupid 720p).
If you have DJI Osmo 2 you have good application for timelaps. But still no super wide-angle
Timelapse with the original camera app in high quality
Framelapse is not bad, but as mentioned, you can't use wide angle lens nor the quality of the original app. Solution:
Use "intervalometer"! This app is working together with any other camera app. It works as an overlay, means, it's running background and given impulse to the camera button with any desired interval while using the camera settings in the original camera app. You can not only use any interval with any resolution (40mp too) but choose a delay when shooting from day to night. The app costs here in Germany 1,89 €.
Grab a copy of Intervalometer from the Google Play store, then you can shoot your own timelapses with whatever camera application you want. That's what i do and it works great!
/ Magnus
With just one camera and no chance to select the other two, probably wrong colors and no raw files support, useless.
EDIT: Oh wait, this thing is actually useful, its no camera app instead it hijacks what ever is on the screen and simulates a touch in the timed intervall.
So it remote controls the manufactures app with whatever is set there.
Nice. Sorry I dismissed it so fast, I was just expecting another dumb comment but this is really useful.
Exactly, it is one of the best applications i have found on the Google Play store and for this purpose it's fantastic! you can shoot RAW timelapse sequences if you want to, the possibilities are infinite since it's not relying on it's own camera but let's you use any camera application you want. It's worth paying for it since it does such a great job with timelapse photography.
/ Magnus
Ok, the best timelaps is INTERVALOMETAR.
You can use every mode, normal, super wide angle, HDR, Night mode, zoom and etc...
