Hi, I have an Iphone 5 and want to buy a new one. Some days ago I was at the Apple store and I was testing the cameras of the Iphone 5s and 6s. Iphone 5s was better for sure. While zooming the photos took with the 6s I noticed that on the background there was a big loss of details due to the new "noise reduction" function introduced by Apple in the new 6 generation phones. I think that the 6s without this noise reduction feature would be awesome, so someone know a way to avoid this? What about using an app like Camera + or something like that?
