Hello guys!
Several days ago I bought iPhone 7 Plus. Previously I use iPhone 6s. When I start taking photos on my new 7 Plus I decide that image quality is bad and my new phone is defected. I notice some watercolour effect. I think - I need to compare images on monitor side by side. I take one shot of object on both phones (focus on text). Here is result (image resized by 50%, left - iPhone 6s, right- 7 Plus):
As you can see on 7 Plus image quality are better. But another example (image resized by 50%, left - iPhone 6s, right- 7 Plus):
You can see some kind of watercolour effect, right? Here is how new camera focus works. This is not bad, this is just new camera, new software. Another example (image resized by 50%, left - iPhone 6s, right- 7 Plus):
Again, looks like in iPhone 6s quality is better. But it is because new camera focus. I am not sure that this is good or bad. I think Apple can fix this in software update. This is just image processing after taking photo I think. Final example (image resized by 50%, left - iPhone 6s, right- 7 Plus):
iPhone 7 wins I think. Image more clear and sharper. I like it.
I am not sure that this is a problem with camera or phone. Software - maybe yes. Apple can add settings for Camera to tweak blur processing after taking photo.
On new iPhone 7 Plus you must watch on what object you are focusing. And photos will be good.
P.S. Here is not zoomed images (image resized by 50%, left - iPhone 6s, right- 7 Plus):
You can see blur or watercolour effect at the top of the image on iPhone 7 Plus photo.
