    this is the auto mode where the colors in the pic were very much saturated and unreal and different from real world trucolors

    this is the pro mode and the real world color is the same as here...

    Well that's what pro mode is for...
    No post edits, no scene detection, no HDR kicking in... ;)

    Nope he has a point, the WB left in Auto even in Pro mode is quite far from accurate. Using lets say Lightroom is also far from a smooth experience. With 99% of the Phones when you press Auto in Lightroom they will show you a decent result, with 7T Pro the image you get is weird and the Auto makes it even weirder. Now yes you might want everything manual but giving the user (especially in a phone) a close to usable settings is a standard.

    I can't force pro mode in every pic I take....sometimes u just have to be quick to capture important and best moments.. afterall the whole concept of great camera in a mobile is it's ease of use
    if pro mode what u say, I will definitely prefer DSLR

    Lightroom doesn't have Auto Whitebalance correction... You need to pick an white or better neutral gray area in the photo with the eyedropper tool...

    Yes OnePlus needs to work on AWB, especially in artificial light situation, and homogen light colors that completely fade to gray...

    But Whitebalance isn't really easy and even with an DSLR there tools like color correction charts and Neutral gray cards to help to get the right Whitebalance in post..
    For that a hardware calibrated Monitor is a must to see what you get...
    Here's an example...
    The right monitor has not the same colors although they are both set to 6500k..
    IMG_20200227_201411__01_001.jpg
    After doing a Hardware calibration with Studio- Matching there's only minor differences left...
    IMG_20200228_105116__01_001.jpg

    For Automode on the phone the shot are warmer and more saturated because most users like it that way...
    If one sets the screen calibration to vivid on the phone it will be even more saturated...
    A lot is in the eye of the beholder... ;)

    That being said..

    It's not easier to shoot photos with good quality with a smartphone than with an DSLR on Automode...
    Tiny sensors and optics are still the bottleneck in smartphones...
    But in most situation the OnePlus camera does a pretty good job IMO...

    I notice same behavior, it's going everywhere in auto mode. Absolutely completely unrealistic. Pro mode but better. But why no hdr available in pro mode?
    Also issues with focus on smaller objects. Much worser then S10 which is not champion. Best was apple xs Max.

    So I am not sure if you can see, this was just an example shot to see if I was actually tripping or not. That desk should be white and as it can be seen the lovely magenta is out of this world.

    Sure I can see it...

    What you see isn't what the camera sensor sees...
    You can sit in a green lit room and have a white plate before you and you will see it white because your brain just does it's own white balance...
    The camera sensor sees green light reflecting of the white plate and has to guess AWB caus it doesn't know what a plate is... ;)

    I got an example for you...

    I wanted to shoot some melting icecubes...
    We all know ice is clear and white...
    I lit the scene with a cheap, very cold white flashlight..
    First try almost good but overexposed and too much reflection.. a little to the blue...
    IMG_20200122_181858_001.jpg

    Then I moved the light to the side and a bit to the back to get more details from inside the icecubes...
    And this happend..
    IMG_20200122_183210.812__01_001.jpg

    Light passing through the icecubes changed the wavelength to blue and AWB came up with purple although my eyes told me they're still white..

    Now in Lightroom using the eyedropper tool give a custom Whitebalance and reality back...

    Screenshot_20200229-120625_001.jpg
    As you can see I choosed a gray spot for WB correction...
    Final imagine..
    IMG_20200122_183210.812__01 (1)_001.jpg

    Your Image corrected..
    Screenshot_20200229-122635.jpg
    I think it should be closer to reality... ;)

    So the sensors just see Lightinformation and AWB tries to make something out of that information without knowing what is actually in front of the sensor... ;)
    The more surrounding light with full spectrum it gets the better the AWB...

    So why does AWB work better outside in natural lighting...?
    Because of the Color Rendering Index (CRI) now Ra...
    Sunlight and old lightbulbs have an index of 100%
    LED vary from 65 to 98...
    Fluorescent light from 50 to 98...
    So it's important to look at the Ra value when buying lights...
    This one is midprice and got 90% color rendering...
    IMG_20200229_132058__01.jpg

    IMG_20200229_132108__01.jpg

    Cheap Lighting with poor color rendering can also effect indoor photos... ;)

    Your brain will see the light/color as it get reflected to your eyes, it does not auto correct making it eg White, eg black women painted white we still see black woman?😃...sorry....it's just not how brains work.

    of course is a white surface still a white surface if the full spectrum is reflected from it...
    Maybe I should've put it more subtle and say there's situations the brain does color correct what we see...
    Called color constancy...

    Have a look... ;)

    Everything about OnePlus' image processing algorithms are poor. I have a Samsung J5 which produces better images. OnePlus just don't know how to code their algorithms when it comes to image processing. The hardware is fine - it's the software that's to blame. GCam does a much better job.

    first pic is gcam and the 2nd is op7t camera app. true colors are sort of in the middle. GCam saturates and contrasts more but has better dynamic range.

    I prefer gcam for portrait modes because OP camera makes everything pinkish.

    Thank you for the photos..!! :D

    Hmm...
    You sure that pic nr 1 is Gcam...?
    Way to cold and too much contrast... Imo..
    1251087-fa1d0203558418d04d0ee0dd5d59af73.jpg
    Custom WB on the white stripe of the sheets..
    Screenshot_20200301-090853.jpg

    Custom Whitebalance on the wall. I really like that warmer touch
    Screenshot_20200301-084324.jpg

    The second is also a bit to cold but probably a bit closer to reality custom Whitebalance doesn't change that much...

    1251088-5260ba0575a36068cca5c61de0059bdb.jpg

    WB on the sheet
    Screenshot_20200301-090829.jpg

    Again WB on the wall...don't know what is reality but like it better... ;)
    Screenshot_20200301-084738.jpg

    Also a comparison to the Samsung would've been nice... ;)

    Using gcam 7.2 latest version hdr enhanced enabled difference between oneplus cam app,
    Gcam:
    A bit more overexposed, more towards white
    Sharper images, better focus
    Less power consumption, 50 percent
    Saturation also a bit less.
    Playing with controls , advanced mode it makes better pictures.
    One plus in pro mode about equal.

    so it looks like I was using an older version of gcam. I'll try to get better/more updated pics today of the same dog if possible haha.

    ok I'm back with more pictures of the dog.

    here's the OnePlus 7t stock camera
    1583078509786.jpg
    and the gcam 7.2 port
    1583078532387.jpg
    and for fun, the pixel 3a

    and here's another comparison:

    oneplus stock portrait mode: pink tone, washed out, smoothed features (guess this could be a + for some people)
    1583079389409.jpg
    GCam 7.2 port: hugely better contrast and dynamic range. More saturated. maybe a little overly done but I like the look. it's very "pop"
    1583079436091.jpg
    and finally pixel 3a. probably the most true to life photo in terms of colors and dynamic range.

    Yep. Did you enable HDR control in settings on gcam and OnePlus cam? I am able in gcam to set / enable HDR enhanced and set the white control using pixel 3 or 4 or the Sony control and also in advanced mode more settings to enable lib to adjust many aspects. I have 7t pro, I think same main camera?
