    I have the same problem with a few of my old iCloud Photos. I’ve just accepted the bit rot, but one day I might actually get around to setting up backups on a ZFS file share.

    1. 3

      What do we think the cause is? It seems unlikely to me that physical bit flips would cause this. Lossy compression software gone wrong?

        My guess is they are trying some experimental JPEG XL options for thumbnail level images.

        1. 2

          One thing I’ve seen mentioned one of those JPEG sequels like HEIF or whatever, so I could see that they’re trying to optimize the hot thumbnails and proxies you get to see and mess with before the original has time to get retrieved.

          In Lightroom non-classic, I jumped to a photo from Dec. 31, 2020, noticed it was a “Smart Preview” proxy, made some edits, and at some point it had finished downloading the 30mb raw. I didn’t notice any visible change once it quit working with the proxy and started on the raw directly, but the original is bigger than my screen and may not be in the same color space either so ¯\_(ツ)_/¯

          1. 1

            My first thought was that Google has been experimenting with running the images through some sort of lossy NN compression system, but on a second glance I think that’s less likely.

            1. 1

              Some people report that clicking on edit on the photo helps. Not really sure what that implies though, but maybe just the exported/cached format causing issues? Some conversion from a format used back then maybe?

            2. 2

              Anyone have a good solution for downloading all their Google Photos en masse? Takeout is really not great at the size of media I’ve accumulated on Google Photos.

              1. 2

                I would add that the Google Photos download process simply does not work for some accounts, if they need to “verify that it’s really you” but have blocked any possible verification methods.

                  Whoa, rclone also seems much more supercharged than the name would suggest: https://ivymike.dev/upside-down-backups.html

                  1. 1

                    Somebody in the HN thread mentioned https://github.com/gilesknap/gphotos-sync that I plan to try out.

                  2. 1

                    Why would four people flag this as off-topic?

                    1. 2

                      Because it’s not very technical

                      1. 2

                        It’s not suprising to see a service having some trouble. Eventually they might or might not resolve this but either way it’s more expected that they won’t share any insightful information on this incident.

                        1. 2

                          Product information is off topic on Lobsters?

                          Lobsters is focused pretty narrowly on computing; tags like art don’t imply every piece of art is on-topic. Some rules of thumb for great stories to submit: Will this improve the reader’s next program? Will it deepen their understanding of their last program? Will it be more interesting in five or ten years?

                          This post meets none of the criteria. “it’s relevant because it’s a JPEG compression bug” is the same as saying “any website is relevant because Nginx serves it”. There’s no technical content.
