I currently have a very messy system to store my photos where I have a backed up main archive and when I want to edit or work on part, I copy it to a mac, end up with a bunch of edits there which may or may not make it back into the main archive, and when I want to edit on another mac, I copy from the archive there. In the end, I get a lot of duplication, I lose files, and I have a tangled mess of files in my main archive, so it's almost impossible to find what I want later. I hope iCloud drive can help me sort this out, but I have no idea if what I'm picturing is how iCloud works. I'd like copy my files directly from the cameras and have them stored locally on one Mac which I can easily edit, and also have those files backed up online. I then want to be able to edit the online copies from other macs without storing local copies, but have the edits synced back to the mac with the local copy. That way I will only ever have a single folder from each shoot with all edits in it no matter where or when the edits were done, the files will be safely backed up online, and I will have a local copy of everything kept up to date. My photos come from 2 SLRs (shooting raw) and 2 iPhones, and I edit with Adobe Camera Raw and Photoshop, so I don't think the Photos App will do anything for me. Also, I spend much of my day with my only internet through cellular tether to my iPhone and I don't want to use this very limited cellular data to access iCloud, syncing should only ever happen at home on my fast unlimited broadband. Even though I spend a lot of time editing large photoshop files while connected through tether. Is it possible to do all this with iCloud? Thanks for any help you can give.
