Cannot delete image that are on iphone with image capture
Ok so I am a little confused when I connect my iphone 6S to my macbook using image capture.
Connecting the two, in image capture i see there are 5.618 image when I select my iphone on the left plane in image capture but when I go to photos on my phone the first tile I see is called ALL PHOTOS and it has 11.152.
I wanted to select about 5.000 of the photos in image capture and delete them, but the delete option is greyed out. So I though, then I will delete them directly on the phone, but there there are over 11.000.
Why woud image capture not show the same amount of photos (11.152)?
How can I re-acivate the delete option in image capture please?
