Just started watching a YouTube video on using Snapseed to edit photos on the iPhone. I send my iPhone photos to Photos in my MacBook Air and, if I am particularly interested in enhancing the photo, I do my editing with the MacBook Photos app. I gather in watching this iPhone photo video so far, that the idea of Snapseed is to do all the editing on the iPhone. I find myself at a loss understanding why I would want to do that all on the iPhone and, I guess, store all my photos on the iPhone. I guess I am having a hard time picturing (no pun intended) the relationship of editing and storing between iPhone, Photos and maybe even iCloud. Was wondering if anyone could put this into focus for me? Thanks!
