Sorry, but the problem with the vertical lines has NOT been fixed with the new iOS 7.0.5 update!
I noticed these two big problems with my iPhone5S (IOS 7.0.6) and my iPhone4S's wife (IOS 7.0.5):
1. VERTICAL LINES
My original shots are clear and sharp but after saving to the camera roll (simply "open and save without processing" an image with every apps, i.e. Snapseed, Filterstorm, Leonardo etc.) some lines appear and I notice a great degradation of image quality.
2. PHOTOS TURN PURPLE
Every time I save an image to the camera roll (again, simply "open and save" the image with every apps), it turns more and more "purple". Actually, it's impossible for me to get a PURE BW photo in my camera roll.
I made some tests with the iPhones of my friends (IOS 7) and the same issue occurs.
Below is an example. Because of this problem is more evident with BW photos, I use a shot taken with camera app simply converted in black and white. First image is a crop from the original BW shot, the second one is the same image opened and saved (without processing) with Snapseed about 10 times. Same problems occurs with every apps I tried (Filterstorm, Photofx, VSCO, Afterlight, TadaaSLR, Leonardo, PSexpress, Noir etc.).
Note: enlarging the image (i.e. with Filterstorm), the problem is visible after 2 or 3 times.
This is the original image:
This is the "final" image (after about 10 times of "open and save" without processing):
Crop of the ear (original image):
Crop of the ear (finale image):
Have you noticed these problems?
If not, please try to reproduce it (only IOS 7) simply opening and saving (without processing) a BW photo about 10/12 times and compares the result with the original one.
Greetings from Italy, my friends!
