Aug 27, 2019 at 20:02 comment added Eric Duminil @kbcons: Darktable, Capture One, RawTherapee or Aperture (now discontinued) all work this way. Every modification is reversible and only applied once during the export process, without overwriting the original file. Converting the original JPG to TIFF simply doesn't help at all and only requires a lot more disk space.
Aug 27, 2019 at 19:31 comment added user86484 @Eric Duminil: Lightroom is, I suppose, the standard, but it isn't the only thing available that provides the same (or very similar) functionality with a perpetual non-cloud license. Which is, of course, a subject for another time.
Aug 27, 2019 at 19:18 comment added Eric Duminil @kbcons: Thanks for editing your comment. OP asked about Lightroom though, and Lightroom doesn't overwrite the original file (either RAW, JPG or TIFF). Your "lossy cascading" will never happen in Lightroom.
Aug 27, 2019 at 19:09 comment added Eric Duminil @JPhi1618: We agree on this one, it wouldn't be a good idea to use a 1995 workflow in 2019. Hopefully, OP asks about Lightroom and Lightroom doesn't work this way. See this comment.

Aug 27, 2019 at 18:02 comment added Andrew Morton @JPhi1618 One wouldn't repeatedly save as JPEG and reload at intermediate editing stages: I think we would all agree on that. However, for starting a new edit from the original, it is best to start from the original JPEG - it could be that an improved JPEG decoder becomes available.
Aug 27, 2019 at 17:07 comment added JPhi1618 @EricDuminil, So if you edit a JPG a bit, save it, close it, then open it again, make an edit, save it, close it - that's something you are OK with? You would say that saving a file in a lossless format for repeated edits is useless? Maybe OP could have been clearer, but if you intend on editing a file over and over, you don't save it as a JPG.
