Google Issues Quality Warning for Millions of Google Photos Users
I got burned by this.  I take 4x5 film photos and stored my library in Google Photos as 80 megapixel TIFF scans.  One day, they told me I was out of storage, and that all the files were converted to phone-quality jpegs.  They look awful.I got into this situation because I had a few terabytes of free storage that I accumulated while working at Google; there was some deal like "fill out this survey and we'll give your personal account unlimited free storage forever"... but they altered the deal and that storage went away.I use iCloud now.
