P: TIFF compression settings have no effect when Lightroom sends image to Photoshop for editing

Hello, I believe this is a bug..When using edit in Photoshop from Lightroom with TIFF format set, none of the compression settings work. Because when the file is saved in Photoshop (ctrl+s) and comes back to Lightroom it's always an uncompressed TIFF. Every other setting works.Unfortunately I can't tell whether the fault is on Lightroom or Photoshop side..Tested on Win 7 - 64bit with LR 3.6 - 64bit and PS CS5.1 - 64bit, also on Win XP - 32bit LR 3.5, PS CS5. (In both cases camera raw version match) Lightroom 4 behaves the same.I would appreciate your replies, Thank you

    I just tried with LR 4.1 and Photoshop CS6 trials on win7x64 and this bug is still present! Tiff compression setting in LR has zero effect.

    For example, I send 4 images with merge to panorama in Photoshop and if I don't want to end up with 700MB+ file I need to do save as with compression in PS which doesn't send the output file back to LR catalog so I need to synchronize folder to have it in catalog. It just breaks the recommended workflow.

    Please Adobe, do something with it. Thank you

    No, size of the saved file is the same as indicated in photoshop image size dialog. The point is that the image coming from Lightroom should keep the compression settings in Lightroom preferences when it's handed to Photoshop. I found out when I merged 3 images from Lightroom to panorama via edit in ps and ended with one 900 MB file when saved, even though there was compression set in LR. It just doesn't work.

    Yes, save as option in Photoshop is a workaround, but this is not the way it's supposed to work I think. I don't want to change compression because I have it already set in Lightroom edit in preferences. Ctrl-S in PS should keep all the settings and hand the file back to LR. It keeps all settings such as bit depth and color space except compression. But thanks for your reply

    If you save a flat file as a Tiff in Photoshop and the file’s size in the Finder is less than the size as indicated in Image > Image Size then obviously it has been compressed – are the files smaller or not?

    But you mention ctrl-S, to change the compression settings from Photoshop you would have to do a File > Save As.

    Come on, anyone? I know there is more important stuff to deal with these days, and it ́s not that crucial, but I just wanted to bring this to attention, becasuse there are new versions of LR and PS still on their way. And this seems to be an obvious bug.

    It would be nice to hear from some of you or Adobe. I tried it on 2 different computers and it was the same. If anyone can just try it as well and confirm this behaviour or not. It ́s pretty quick.. Thank you
