    So... I did a newborn shoot in the fall and at the time the client wanted digitals and single prints, so I saved the edits in JPEG. Now months later, she decided she wants an album. With my printing company, I have to design the album page spreads first in a Photoshop doc, and then add the compressed spread to the album pages. This results in double jpeg compression. My printing company will take TIFF or JPEG only. Is there any possible way to save these photos? With the double compression I am getting banding and the colors are getting funky. Obviously in hindsight I would have saved them in PSD.

    Seeing examples might help. A second pass of JPEG compression should not result in visible banding.

    why not recreate the spread in PS with original sized photos?

    I can't use the raw files because I saved all the edits in the high res JPEGs. The images took probably 8 hours in post to edit so re-doing them is out of the question.

    I am using the original size edited jpegs to create the spread in a PS doc, but then when I save that it obviously compresses a second time.

    So why not open the edited JPEG's and save them out as Tiff's to build the album rather than compress them again as JPEG's for album production?

    Lesson learned right?

    You edited the camera JPEGs instead of the raw files?

    Most likely then the problems you're seeing aren't caused by a second pass JPEG compression but rather by your original editing of the camera JPEGs.

    Pixel-level edited in Photoshop?

    edited parametrically in say, Lightroom?

    Sorry that I am just seeing this now. I do not use Lightroom, start to finish in Photoshop. This issue is still not solved BTW

    The once compressed final edit JPEGS do not have the banding. It only happens when I save the the file again as an album spread.

    Yes, lesson - always save the PSD's.

    Miller's complained about the tiff's because they take longer to upload. Whatever, that's what they will get!

    And no, I didn't edit the camera jpegs, I don't even save jpegs in camera, only NEFs. I use camera raw to make simple adjustments, but the majority of my editing occurs on the main photoshop platform (head swapping, skin corrections, dodge and burn, nip and tuck for new moms who request it), so clearly these changes are not saved in the source files.

    I compressed the final edit into a jpeg without saving a PSD file. If I have to go back to the raw files and re-do all the post-camera raw edits, it will take hours.
