Guys, after seeing all these smeary photos on here I decided to file an enhancement request about the new iPhones. I ordered an iPhone 6 but I haven't received it yet so I can't comment on the image quality, however, I think it is important to point this issue out to Apple and I ask you to do the same if you feel worried like myself so they can fix it in a subsequent software update.
Here's a copy of what I sent them:
"I am writing you because I am worried about the amount of noise reduction applied to the photos taken on the new iPhones, I have seen photos on several Apple-related forums where heavy amounts of NR got applied to the photos taken in already sufficiently lit scenes, however, I don't own an iPhone 6 yet and I can't confirm if any of this is true. It seems to me that your top priority this time around was to get the photos as low-noise as possible. As a hobby photographer I know that noise reduction creates smearing artifacts which don't look any good. NR can always be applied later, if needed. In fact, I ask you to reconsider the image processing steps taken on the new iPhones because in my mind the amount of NR applied is so much it severely affects the quality of the images."
