Dual Lens Question - Huawei P20 Questions & Answers

Hi,
Huawei says that both lenses combine to take richer photos.
Does it really work that way? What happens when u take a photo with one of the lenses covered vs uncovered?
I seem. To see no difference. So to me it seems the second lens is useless. Only for bokeh?

I think so honor 8 camera dual tech is fake

I've been honor 8 since one week and i have found one thing that when even i cover right side lens it capture black image but when ever i cover left side sensor it's take snappy sharp image like it's ideally take . So i think so it's just fake second camera is dummy or any other problem ? please let me know i'm worried for my money
Are the pictures good? If so then don't worry about it.

From my experience the second camera is mostly used for background blur effect. If you cover the lens, everything is in focus.
It is also used for minor noise reduction. If you take a picture in low light and cover the secondary lens there is a little bit more noise. But you won't really notice it unless you enlarge the image.
well the fact that when you block one lens, the other works is proof that neither is dummy. perhaps the post processing is not that dramatic as you were expecting. try taking low light pics with both and just the normal lens then compare them by zooming.
no difference found
I've tried in low light too but second lens is just a fake . it's don't enhances quality i think so i have to wait for android N update

I love the pictures the Honor 8 takes when using the Wide Aperture mode. It seems the second camera is essential for creating the blur effect. If you haven't noticed you can go into the Stock Huawei Gallery and adjust the wide aperture pictures after the fact. Even if you took a picture that looked like you focused in on the wrong thing, just go into the Gallery, click on the wide aperture button (only shows up on wide aperture pictures) and select what you wanted to focus on.
Sure enough, without the second camera the wide aperture mode doesn't work properly if at all.
Second lens is for focusing, depth of field, and additional light. As well, when covering the second lens, it persistently gives a warning about not covering the lens while shooting, especially when refocusing. I think this should be enough to disprove your "fake camera" theory.

Galaxy Note 8 At&t taking noisy pictures!

I recently bought a used note 8 which is taking very noisy (grainy) pictures, especially from telephoto lens. I'm really loving this phone but I can't live without a good camera. Is there any way to fix it?
I guess it is a hardware fault because I have also tried different camera apps. Any help would be much appreciated.
Thanks!

Tried for hours, unable to upload.
Let explain to you:
Pictures taken has so much grain (which comes when ISO settings are set high). I have tried pro mod, it do makes a difference but is very laggy (slow shutter speed)
In short, pictures are too much noisy. Noise is clearly visible in viewfinder, specially when taking close up shots, using live focus or telephoto lens.
Primary lens also has too much grain visible when zoomed in.
I had used iPhone 7 plus which can take spectacular photos, note 8 pictures are worse than iPhone 6's. Definitely not what I wanted
Well, it is still a digital zoom, after the 2X optical zoom. Some of my zoomed pictures look like crap, but others work pretty well.
examples;
Looks pretty good, was documenting the hole in the side of a building. I was about 30 feet away, zoomed in pretty much all the way.

This one is pretty crappy. Owl was in the basement of my barn, 12 feet away.
https://photos.app.goo.gl/o4I0O8mukoOfBMsj2 No zoom for reference. https://photos.app.goo.gl/47vRH3xgXWXTjFJ02 <-- Not so brightly lit.
Your pics are better than mine.
Of course pictures loose details when zoomed in digitally, but mine is different story. It shows grains even without digital zoom. It shows visible static noise. Your pictures are waaaaaaay better than mine. I might return it today. I'll miss it, It's a great phone ?

Yea, if it's showing grain without zoom, something's wrong with the camera.

Returned it!
I had the same problems. Them I sat it to 4:3 (12M). Turned off HDR, made sure I didnt use live or manual focus and my pictures are great! Check this site out. Youll see side by side comparisons of off the shelf note 8s and Iphone 8s. High end DSLRs require settings changes and different focusing and lighting for some pictures. But they are huge and expensive that they have room for all the mechanisms and sensors that you pay a hefty price for. This is a phone and some places you may have to use pro mode to get the right shot. The phone doesnt always know what a good picture looks like to you and in some cases cant figure out what to adjust to clean up the picture. Practice with pro mode.

Ultra-wide angle camera color science is off?

Apart from the frustrating fact that you can't record video and that the ultra-wide lens isn't very wide, the colors and seem to be extremely off in the comparisons I've seen to the point that I don't know if it's solvable through a software update. Maybe fixing the distortion and the super low saturation through software will somewhat save it, I don't know. Heck, even Mi 9 has a clearly superior ultra-wide WITH recording. What do you think? Does anyone that has the phone have a different experience? I want to buy this phone, but at this point in my country it's about the same price as a S10+ (Exynos) and I'm struggling to make a decision.
I wish GCam mods come early to save this mess.

I cannot answer specifically to the 7 Pro, but I can tell you that the colour science is off on my now-sold Galaxy S10 Plus Exynos version. Switching between the main lens and the wide angle lens in the same exact lighting and spot yields different colour reproduction. It might be down to the actual lens used in junction with the software, but I can safety say that this problem isn't exclusive to the 7 Pro if anything.
Also, don't buy the Exynos version of the S10. It has garbage battery life, and has different camera lenses to the SD version that have shown to be inferior to the SD version.
There is a setting in the camera called "Ultra Wide Lens Correction." I wonder if testers are switching this setting to see if this is the issue. I just got mine, but it's night time right now so I will need some time to test (but I only have the LG G7 ThinQ to compare to.)

Yes, but at least every other wide angle camera in the market gives decent results. 7 Pro's results are very undersaturated, very soft and sometimes seem like out of focus.
I know about the S10+. If it was a Snapdragon version I would have already bought it.

Great! Post some samples when you can. I'm not that worried about the lens correction, I don't mind the distortion. My problem is mainly the saturation and softness of detail. If you can, post original results + "corrected" versions using Snapseed/Photoshop to check if some post-processing saves the day at least. Thank you in advance!

Beauty of OnePlus and this wonderful community is the fact that there'll be GCam for it very soon, and we'll undoubtedly be able to take amazing shots through GCam using the wide angle lens.

It really depends. It might not be fixable with gcam.
The main camera uses a pretty good sensor. But it is a different sensor for the wide angle lens. So the quality of the wide angle shots will heavily depend on the quality of the sensor they use for their wide angle lens. It might be a weak sensor, we don't know right now. Huawei uses 4 Sony sensors for example, their wide angle pictures are pretty good. And yes, the best hardware is useless without a good software. But the best software also can't fix a bad sensor.
Not saying that it is a bad sensor, it's just that we don't know by now. We might have to wait for a teardown and some talented devs to see what is inside and if it is fixable.
I can only link you the specs from dxomark:
Primary: 48Mp Sony IMX586 sensor (12Mp output size), 26mm-equivalent lens with f/1.6 aperture and OIS
Ultra-wide: 16Mp sensor, 17mm-equivalent lens with f/2.2 aperture
Telephoto: 8Mp sensor, 78mm-equivalent lens with f/2.4 aperture and OIS

What is the minimum focus distance of the wide lens and the telephoto lens?

Just curious to get a estimation for how good macro photo's can look on the p40 pro, so im wondering about how much minimum distance is required for these two lenses to have a object in full focus.
does anyone know or can check?
10cm and you can use x3.5 zoom and still looks like macro without loose quality.
Hard to do screen with knock to get still sharp screen
what about the telephoto lens? perhaps you can make even better macro's with it.
I mailed huawei, they say for the p40 pro+ it is 240mm for the telephoto lens as the minimum focus distance.
I am very much doubting that this is correct haha.

Why new phones have 3 or more cameras?

I don't understand why new phones have a lot of cameras and only one camera have a lot of mpx other have 8mpx or less, is it so hard to make 1 better camera than fill whole back of the phone? Also cameras stick out on new phones so is easier to break it. I think is better to make just one camera with e.g 48mpx than 3 more. Also in my opinion professional camera should be to making photos than normal smartphone.

Welcome to XDA.
Multiple cams because there's inadequate space for a optical zoom lense.
It's just marketing thing. 3 cameras are "better" than one good main camera.
All these 8MP ultrawide cameras and 2MP macro cameras are pretty much trash.

My 12mp ultra wide does ok even with the fixed focus. When you can't pan back ultra wides are your only option.
My biggest complaint is that the cameras aren't well protected. A sapphire lens cover would be fairly scratch resistant, but would probably add a bit to the cost.

A good case is all that's needed. I live in the desert (sand and grit everywhere) and this N10+ is 3.5 yo has zero scratches or mars on the factory cam protector.
Case it, keep your fingers off the cam protector and clean with a dry microfiber cloth occasionally. No fuss or bother.
They are generally cheap and easy to replace if damaged.

My bad, yeah 16mp. After the N10+ Samsung went nuts with the cams. The N20U ie the humpback. Then then the bs highest mp count race was on.

With regards to thread's title: I think this article
Why Do Some Smartphones Use Multiple Cameras?
Lots of high-end smartphones have added multiple camera modules and lenses to the back of their designs. But why? The fact is that they do different things for different phones, so we’re here to break it all down for you.
