Since the very first photo I took with my iPhone 6 I realized something was wrong. Everything looked like a watercolor painting. In comparison my old iPhone 4 took much more detailed photos. After some tests I started suspecting there was a VERY agressive noise reduction filter algorithm turned on in the iPhone 6. In fact...Apple's sold this filter as a feature at their website (even their own sample pictures showed lack of details ought to this filter) I waited patiently for a year to Apple to fix that, and even decided to buy their next phone in case they finally fixed it...unfortunatly the 6S noise reduction algorithm is even worse: This is the new iPhone 6s: Take a look at her hair (1:1 pixels please): https://cdn2.vox-cdn.com/uploads/chorus_asset/file/4096340/iphone6splus_portrait .0.JPG Now a normal phone with a normal noise reduction algorithm: Galaxy 6 Edge https://cdn3.vox-cdn.com/uploads/chorus_asset/file/4096350/gs6edge__portrait.0.j pg Also here you will find lots of samples showing how bad iPhone 6 pictures are: https://discussions.apple.com/thread/6576391?start=0&tstart=0 Of course it doesn't matter if you use a different camera app, since every single camera has to acess the harware using the camera framework. Anyway today I started researching and found LOTS of noise reduction parameters in the CameraSetup.plist at my iPhone6's \System\Library\Frameworks\MediaToolbox.framework\N61 folder. I've been doing some tweaking and definetively I got some results. First I tried just to replace every noise reduction value with 0 and all I got was green photos Later I just deleted the NR2Parameters keys (apparently Noise Reduction 2 algorithm is the new one added with the iPhone6 which makes everything look like a watercolor)...and in that way the Camera app didn't work. But, when I changed <key>NoiseReductionMethod</key> <integer>2</integer> to <key>NoiseReductionMethod</key> <integer>0</integer> Something happened. Suddenly some fine details were much bettter than previously. But others were much worse. Every time I make a change I have to reboot the iPhone, take a photo and compare with the pc at 1:1, so it's a bit slow. So, here I am, asking for help to those of you who know better than me the internals of ios. Any idea about which parameters to tweak? Thanks in advance.
