Monochrome combined with depth feature - Nokia 9 PureView Questions & Answers

I'm considering buying the Nokia 9 and I am wondering if the camera can use the depth changing feature (bokeh) when taking monochrome pictures. I really enjoyed the monochrome camera on my old Huawei P10, and adding bokeh on black and white photos would be nice.

I know it's an old post, but for the ones wondering, there is no Depht setting for monochrome picture. Also, the picture is taken with one of the side B/W sensor, but the screen show what the centered sensor see. So in the end the photo is not centered as seen on screen when the photo was taken.

The thing is ... if the Nokia 9 PureView when shooting in black and white, it does so only using hardware, this is its three monochrome lenses (as it was said that Huawei Mate 10 Pro) or on the contrary (as it seems be that it does) uses the 5 lenses, the 3 monochromes and the two RGB and then desatura with software filter the image ...
If the case, it is confirmed that it is the latter, without problem in the depth map, in fact it seems better option to shoot the Pro mode (capture in RAW) and then in the edition from Adobe Lighroom desaturate the image, without being deceived, since "purely" by hardware, it seems "not to carry it out" in the same way that when the camera captures in color, the five lenses are always used together

it uses the 3 monochrome sensors.. I don't know who tells the opposite... the preview before you shot is from center rgb sensor desaturated.. but if you cover the 3 monochrome sensors and shot.. innthe start you ll see the image of preview.. but when fusing complete you'll see only a black picture

Using both CAMERAS at the same time

I saw a topic from P9 forum where folks discused the question- wether the phone actually uses both camera sensors at the same time... How is this with our p10? I tried to take some close-up shots with BW covered/ normaly- and there is 0 difference- same quality, size etc...
- Only case when I see actually both cameras working hard at the SAME TIME is when using bokeh mode.
BUT WAIT A SECOND. Huawei states that colour sensor is only 12MP ok, but how on the earth it came down that I was able to take 20MP pictures with BW covered???
Sooo, have you discovered something about this? I will try to take some far away landscapes tomorow and see if something changes then...
A Long time ago i think about the Same
How my P10 can take color pics in 20mp when it just have a 12mp sensor

It would be logical, if phone used both sensors at thr same time- buy using BW details combined with colours from 12MP. BUT i tried several times to cover that BW sensor and camera doesnt give a deamn, it takes 20MP colour pics anyway...
I read something about this months ago.
The camera uses both sensors in 20MP and HDR mode.
When you make a 20MP color picture, it makes a 20MP b/w picture and a 12MP color picture as stretched overlay.
With the good b/w contrast it looks really good even the color sensor has only 12MP.
This is also the reason why you can't use optical zoom in 20MP mode.
The zoom works with the b/w sensor, so it's not really optical zoom but "enhanced digital zoom".

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.

[Camera] Is it just me .....whats your settings?

Ok coming from Samsung , HTC, Asus and iPhone (I know I here you gasp)
I pretty much use my rear camera alot for work purposes, no selfies
Mostly its point and shoot I do and I know the camera on these are for ppl getting the right shot manually due to the settings
Have tried apps on this phone Like :
Camera FV-5 (same kind of results)
Open Camera (which seems to stay active in the background)
Now heres my question if you quickly take a photo, point and shoot (focusing first) using highest resolution
Once you zoom into the taken picture, its all grainy even if its took about 3-4 feet away from you
Now, if you take the same picture with monochrome its a better pic and if focusing on say a bottle with writing
Its more visible to read compared to the colour as the colour looks like its a water painting
Are you guys getting the same results or know preferred settings to use?
Thanks
Try to set the resolution to 12mp to enable the 2x "optical" zoom.
The color sensor is only a 12mp one, the monochrome sensor has 20mp.
If you enable 20mp in settings, the camera will make a monochrome and color photo and merge them into one. This is also the reason why the 20mp photos are a bit blurry or too bright on edges.
So, use 12mp and the grain should be mostly gone.
Here are three shots by me:
https://imgur.com/a/BYf7kIX - played with focus, no aperture feature.
https://imgur.com/a/xA2qURk - just a free hand picture in 12mp without zoom
https://imgur.com/a/RbEdeiI - and the same with 2x optical zoom.

Is this with stock camera? stock rom?
as My pics are no where near as good as this on 8.0.0.379(C02)

Everything stock, 8.0.0.370 on VTR-L29C432, stock EMUI camera.
Can you show some examples?
Desk is about 4-5 feet away from me when taking these shots
Sunny outside
Just normal photo and putting focus on the bottles as shown (seen in zoomed photo)
You can clearly see they look terrible apart from monochrome
No settings have been touched apart from resolution
Zoom is about 4.6x
Monochrome
12MP
20MP
Zoomed in
I put some crap on the desk but if you can see the text is visible on some stuff to give you an idea

P20 Pro Zoom Issue After EMUI 9 Update and Artefacts Present When Zooming

After installing the EMUI 9 update when I zoom, especially at 10x, the photos taken are not what they appear on the screen before taking them. Instead, the photo taken is something that is lower down to what I was trying to take a photo of. For example, if I try to take a picture of the B key on my laptop it takes a picture of the space bar.
Furthermore, whilst this hasn't only been occurring after the EMUI 9 update, very small artefacts that stay in the same position are present at high zoom, especially 10x zoom (they are invisible at no zoom and only become slightly visible at 5x zoom), when the camera focuses on an object. They appear like small white dots (visible when you zoom in on something that is black in colour as the white dots become more visible). However, they don't appear when taking the photo due to post-processing smoothing the photo out. They are not present though when taking pictures in the pitch black so surely they are not dead pixels? You can though see it on video at 10x zoom. The lens is clean. Is this normal?
Any help is much appreciated,
Thank you.
I've investigated the problem further regarding the first issue and I believe it must be something to do with the telephoto lens not always functioning, which happened straight after updating to EMUI 9, therefore, only the main sensor takes the picture, hence why the final photo appears further down than the preview photo. Also, if I take a photo and then look at it in the gallery and then go back to the camera, the preview image is shifted and the image quality is worse, which would make sense if the telephoto lens is not working when zooming. However, it does seem to work sometimes.
Can someone else test this as it must be a software issue.
I'm on EMUI 9.0.0.168
Thank you.
Telephoto lens preview and capturing will only works when the phone decide that the light is sufficient enough. Else it will use interpolated image captured from main sensor.
This been discussed in other threads as well

Panorama mode needs some improvement

Perhaps I'm doing it wrong, but I just can't get the panorama mode to work properly with the S10+.
I have 2 major gripes with it:
The panorama doesn't go all the way around, so I don't get a full 360 degree panoramic photo
The photos always come out distorted/stretched when viewed elsewhere
With issue one, it only seems to take about 350 degrees, so I end up with a stitch that doesn't quite work out when I view the photo later. Apps like Google Photos helpfully turn these types of images into something similar to being there and rotating on the spot but because the phone doesn't seem to take a full photo this doesn't work properly.
On issue two, when viewing the photos in Google Photos or even Facebook, they try to make these images into a photosphere type image, so 360 degrees along the X and Y axis. The trouble is, even though these photos are taken with the wide angle camera, it stretches the image upwards and distorts it to get that 360 view. LG wide angle cameras (at least on the G6 which is the last one I owned) add about 10 degrees to the top and the bottom of a pano photo using AI to match the colours at the top and bottom (e.g. extra blue at the top for sky). This results in a blurry patch at the top and bottom of the photosphere, but also prevents the main part of the image being distorted.
Its a shame about both of these "features" as otherwise I'm pretty happy with the camera, but having distorted panoramas is not great.
