iPhone Photos storage error I have an iPhone 6 with 16GB of storage, and it has been saying there isn't enough space on my device (mainly because I had 6,000 photos in my album with was taking up 8GB). So went on my Mac and transferred all the photos on my iPhone to my Mac, and then deleted them off my phone. It has been 2 weeks now and my phone is still continuing to say I don't have enough space, and that photos is still taking up the 8GBs of storage. 
I have tried turning my iPhone off and on trying to reset it, but nothing is working.
I would try the following:


Turn off iCloud Photo Library 
Turn off iCloud Photo Sharing
Delete all those pictures
Delete the recently deleted folder
Make sure that you have no other photos in any other folder under the Albums tab
Force Reset your iPhone see instructions
Turn on your iPhone and verify step 5 again
Your storage space should be regained
