Anyone can guess whats problem with my rear camera, its just not bright not sharp like before..quality camera is not good as front camera, try change camera resolution to 8 MP or the lowest still got same quallity, 8 MP n the lowest MP got 600 kb of size..
have downgrade to official 4.1.2 and nothing change..
Please help my life..
(btw sorry for my bad english)
The protective lens before the camera might be fogged up or covered up with scratches and dust. Or the firmware for the camera could not be accessed properly.

Try to clean it up with a towel or so.
You say, the 8 MP Photo is 600kb big?

Hi
How have you set your camera ? 12 or 20mb ?
Thx
20mp
12MP RGB

You can select 20 megapixel as the resolution for the rear cameras to shoot, it combines data from both cameras so you can shoot in color too at 20 MP. This can be changed however you like in the camera settings.
I know I searched the internet for this before I bought one because I wanted to be sure. Haha.
In low light better to use 12,cause at 20 mp the image get little bit blurry when mixing 2 images at low shutter speed.
Outdoor u wont be worry to use 20 all the time.
They set the default mp at 12 for a reason

I know, but if you use 20MP, you can not zoom.

A 12 mp sensor cannot shoot 20 mp images, that's impossible. The camera software can boost it to 20 mp though using info from the 20mp monochromatic sensor. Which gives a decent result I have to say!
I am no camera wiz, just a point to and shoot guy. Nor am I a photo conesour in terms of evaluating a good vs great photo. But, I can tell when a photo stinks. Mostly, I just want to set it and forget it and have the best all around chance at good, clear pics.
All that said, I set to 12 and 20 MP and damned if I can see a difference. And it is a very challenging light situation where I just tested (both, IMHO, show off the great camera in this phone). I am outside on patio near midnight, with only light being from a string of Christmas lights in background d an little ambient light from room inside and courtyard beyond the patio. Hard to tell any difference in these two pics. First is the 12 and second is the 20 .. HDR on for both, no zoom.
So what are the situations one would expect 12 to have advantage, same for 20, same for HDR verse flash?

At any rate, contrary to some of the reviews, I think the camera a great with good lightning conditions and pretty good in darker conditions.

A lot of the early reviews were with the pre-release software although some have updated their reviews to reflect that.
I still hear that the camera has trouble with movement in low-light photos causing blurriness. Can anyone confirm that?
I am a photographer and I'm very impressed with my mate 9 camera.
I have used lot of phones but this one is the best by far.
If ur not happy with the auto mode just put it to pro mode and enjoy.

Sure it can, it happens all the time. Let's say this were a conventional 12MP single sensor camera. Would you then be OK saying it can shoot 12MP images? Assuming it had a typical Bayer array color filter, that 12MP sensor really only has 6MP for green, 3MP for blue, and 3MP for red. It does not have 12m full color pixels. Yet that's what comes out of the camera, via interpolation. At least with the Mate 9, it can produce 20 MP of luminance data without interpolation. It's just the chroma data that is at a lower resolution and requires interpolation. But encoding images and videos with lower chroma resolution than luminance is extremely common, because our eyes have much less color resolving capability vs. b&w. See Chroma Subsampling.

Sure, that's basically what I said. This sensor is 12mp (rgb sensor can be boosted to 20mp through interpolation, using the info (captured data) from the 20mp monochromatic sensor. Great results.

The photos are fantastic! To the best of your recollection, would you please share the settings you used in each one. Thanks!
Thats rather hard, I use pro mode and just fool around with aperature, speed and the rest until I'm happy. In auto mode I always point the camera around the subject until I like the lighting and than touch the screen on the point where I want to focus. That's it basically...
Those pic's look professional! Kudos

Hi everyone!
Which resolution do you use, 12 mpx or 20 mpx? 12mpx gives you hybrid zoom x2 but phone only uses rgb lens, while 20mpx supposedly uses both lenses to create a hybrid colour/b&w pic. So which do you use? I have it on 12mpx in order to use zoom but don't really know which is best.
Cheers!
It actually depends on your preference and the situation you want to create in the photo. I use the 20mp when shooting wide angle landscapes, while im using the 12mp when shooting portraits or closeups

Thanks for replying! I've actually found that shooting a normal close up pic on 12mpx shoots in kind of a wide-angle effect. Last friday celebrating carnival at school, I was able to fit in a whole class of 28 kids from a few feet away. If u look at the pic, it looks like it has been shot on a wide-angle lens!
Any more opinions on camera config are more than welcome!
I don't believe that the 20MPx option uses both cameras. When you partially cover the B&W sensor, there is no noticable effect on the photo. Looks like it is only software based up-scaling and may get you jagged edges sometimes. After some testing with 20MPx and then 20MPx resized to 12MPx just for comparison, I prefer the 12MPx default setting.

Hi Marian, thanks for your reply!
So on a phone with a dual camera, what would be the purpose of the dual lens?? If one is rgb and the other monocrome, don't they both work together to provide depth information and zoom? Or do all colour pics use just the one rgb lens and the other is exclusively for b&w pics?? Seems a little pointless to me...
You are totally right about the sw upscale to 20mp as any other camera app only detects a maximum resolution of 12 mp, but it seems strange to me that even on 12mp colour pictutes, the phone wouldn't use both lens (depth and zoom) because the inferior P20 Lite precisely doess that on all the reviews I read about it (I've always thought that was the point of all dual-lens cameras).
Cheers!
The B&W sensor should provide depth information. You can try different camera modes and cover the B&W sensor. The phone says "Please do not cover the lenses." in some camera modes. But if you don't put finger too close, nothing happens. I can't tell it does anything at all to the image quality which seems strange. Did they made some mistake in latest build? It only does have some effect on aperture mode when you can see heat haze effect on display. It sucks we don't have more options like jpg quality or sliders for post-process filters.
When I switch the 3x zoom it's not sharp at all and very grainy, if it optical it's supposed be very sharp,
Is anyone else having an issue with the 3x zoom on the camera ?

Do you have any quality issues using it ?
It's only an 8MP sensor
Did you take a pic? I've noticed that once I get to 6-8x the camera looks super grainy, but when you slide the brightness up or down it tends to make it better, and once the pic is shot the grain goes away and it looks like a normal picture.
Can't upload pics rn for some reason but the 3x looks slightly better than 2.9x with the main camera.

So the camera uses digital drop for 2.2-2.9x zoom?
It is a 2.2x optical system and it takes a "3x zoom" lossless crop out of the taken image, leaving an 8mp resulting image.
So I just received my OP 7 Pro. I love it to this point, though I am still evaluating whether I can adjust to the curved screen. But my question is about the telephoto lens:
We know that the lens is actually a 12 MP 2.2x telephoto lens. The 8 MP 3x pictures the OP camera app produces is a bit of cropping and software zooming. Is there a way - either in the OP camera app itself, GCAM, or some other trick to use the lens as it is actually a designed? A 12 MP telephoto picture at 2.2x zoom?
Thanks...

It crops the 12mp/2.2x zoom image to output an equivalent 8mp/3x zoom image. Just look at the differences in zoom between the portrait mode and the regular "3x" zoom option. Both are using the same lens.

And hence my question. Is there a way to capture the true 12 mp 2.2x zoom image without the OP "magic" of making it 3x zoom. Maybe I'd prefer to crop to a different area of the 12 mp photo?
Just wondering. But I'd like maximum flexibility in camera shooting options...
I know that it will be 2.2x with gcam, or with portrait mode in the oneplus app. I haven't used gcam for a while so I can't find you the latest links and downloads. But hope this info would help
