Horrible iPhone 6 Plus Noise Reduction

No argument. I'm just old school in computers and cameras. And in my field it's a misnomer to call in camera NR a hardware effect. Every company I've worked for including the high end camera manufacturer LEAF has differentiated hardware as something that cannot be changed via programming. Software/firmware is code that runs on hardware but it is code that runs the algorithms that do noise reduction. If it passed through a filter of some sort that changed the light then it would be hardware NR (which I've never heard of). That is why they differentiate between the iP6+ hardware OIS and the iP6's software IS. They both do IS but one (6+) is done through physically moving the lens structure while the other (6) accomplishes IS through a software algorithm.
 
iOS 8 has implemented new demosaicing/tone mapping that causes serious contrast problems.

The good news is that it's caused by iOS 8, NOT the new sensor. A software patch will fix it.

The bad news is that Apple's camera team thought this was a good idea.

I don't remember, has Apple ever refined tone mapping in a .x iOS release? It would suck to have to wait for iOS 9...

They might fix it if they see lots of complaints about it.

Well, we both agree on Cortex's magic in low-light, static situations at least :)

I just found that it provided a little too much 'smoothing' in good lighting situations (particularly on smooth surfaces like a face or walls), whereas the normal camera (or Camera+, etc) gave better detail. Not to say Cortex doesn't provide great edge detail in good lighting - it absolutely does. And that can certainly make some pictures look sharper even if it does median out some fiddly bits that I would rather preserve.

Any chance of of posting a couple of the same shots one taken with cortex and the other with the iphone camera app for comparison.

Kind of makes you wonder why a lot of the professional reviews don't mention this when they get to the "Camera" section. It's usually just unanimous praise. I know diddly squat about photography and still noticed this...

Apple-financed reviews. It's the best phone ever etc.

Finally…!!!
Someone sees the "painted" effect that I started seeing in my photos the first weekend they released the 6. I got mine on day one.

I went to the Apple store last Sunday to have a genius look at some of the HORRIBLE shots I had taken much to my dismay. Even wrote to tech writer David Pogue and alerted him about it. No reply.
While waiting for the genius, I started taking shots with several display phones in the store.
I used a 6, 6+ and a 5s.
All shot in bright Apple store light, no flash.
All showed the same painted effect that this thread covers. I almost just walked out figuring, we'll this is a general iPhone thing and not just a "myphone" thing.

Genius was pleasant. Took my phone in back to a tech person who shot some pattern hanging on the wall they use to test the camera. He returned and said it looks fine to them. I left.
Now, listen. The 6 is my fifth iPhone. And all previous have been fine for photos. Very good for what they are.
I like to shoot, enlarge and take a screen shot of the enlargement. Always crisp and good looking.

But this is bizarre. And unacceptable.
Wanna really get depressed? Try enlarging one of those painted effect shots. Nice if you're an oil painter…
Oh, and try taking a screen shot of a photo and see how blurry it becomes.

Lastly, I have shots from previous phones on my 6 camera roll - they look fine.
Camera Gate anyone?
And don't get me wrong. I'm a total iPhone fan.
But this is bad.

Can you see this shot? Enlarge it.
Bright restaurant, no flash, focused on the woman's face.
Yuck!!!

I didn't believe at first, but I noticed today some horrible "paint" effect exactly as you described. Wow. I'm on an iPhone 6 and really dissapointed that it's giving me horrible pictures compared to my 5s.

1. I have Cortex Cam and I love it.

2. Can you launch Cortex from the lock screen?

3. How many more photos can I take with the native camera during the time it takes Cortex to process one image? I'm guessing over 20+ photos.

4. Explain to me how paying $2.99 for an app is supposed to help everyone in regards to Apples implementation to noise reduction?

Simple! Because cortex camera removes all noise by stacking many photos thus reducing the signal to noise ratio. If you are taking 20+ photos really fast, then you are most likely ignoring the rules of light and composition, without those two important elements the photo is useless. Photographers take their time when composing and shooting a photo, if your not taking the time to compose (which I'm not saying you aren't) and just randomly shooting, then a snapshot is all you'll get. I use cortex camera in the daytime as well as night. And when I take that photo into the Snapseed app and apply the HDR filter on it, or stretch the levels to bring out shadow details, there is no noise or grain in the Photo like there is with the standard iPhone camera.

Paying $2.99 for an app is not a big deal, but it leads me to believe that you may not know exactly how Cortex Camera works. The only negative thing about Cortex Camera is that you have to hold still and it's not good on moving subjects. But it does reasonably well with portrait work and especially for landscape work. And that's how you justify $2.99 to get rid of noise.
