Fixing distorted iphone 6 photos after import to Macbook Pro?
I just imported 3000+ photos from my iphone 6 to Photo on Mac. I found out that more than half of them are distorted, and appear a grey band across. Because I chose "delete the imported photos on iphone" option, now the originals are gone and I'm left with images like this one below. Also, I didn't back up the photos on icloud.
It's a year long memory, and these photos include my graduation, so if anyone could provide solutions, either fixing broken files or pull up images back onto iphone, I would be most grateful.
