Sharing full resolution photos
I share a lot of photos with my girlfriend, friends and family. I use to use shared photo streams until I realized that photos were re-scaled to a lower resolution. I have then used a mix of dropbox, google drive and air drop to share pictures as I cannot compromise on quality. However, when iCloud Drive and then Photos and iCloud Photo Sharing were released, I thought I would finally be able to go back to an Apple solution. However, I have just realized to my complete disbelief that iCloud Photo Sharing also re-scale photos to a lower resolution (max 2048 pixels on the long end). While I understand the limitation for people getting the service for free, I am a paying iCloud Drive customers and I cannot for the life of me understand why Apple, especially with its focus on retina display, doesn't offer a way to share full resolution pictures (which would likely use my iCloud Drive storage). I know I am not the only one bothered by this so does anyone has any idea how to fix this other than going back to using (better) cloud service like Dropbox or GDrive?
