    Lightroom to CS5 to Lightroom and the exposure has changed

    dpick2 Community Member

      Sorry, didn't know how to word the title...

       

      Anyway, I edit a .dng in LR3.3 then use the option to "edit in Photoshop."  I do a few adjustments in CS5 (use the filter/lens blur filter, sharpen) and then save the image as a .jpeg.  The image now shows up in Lightroom but it's a half stop brighter in Lightroom then it was in CS5.  If I were to redit the .jpeg in CS5, I must choose "edit original" to show the correctly exposed image in CS5.

       

      Why is this happening? (And honestly, I'd rather the image didn't show up in LR at all, but that's another issue).

       

      Thank-you.

          Use Export with Photoshop CS5 as the Post Process action if you don't want the image to show in Lightroom.

           

          When you go from Lightroom to PS via Edit in, it's Camera Raw that creates the image in Photoshop, not Lightroom. Sounds like you've applied something in Lightroom to the edited file  if Edit Original exports a different image. If it's a JPEG, check that Brightness and contrast are 0, and your exposure is 0.

            For some reason, Lightroom sometimes incorrectly treats rgb images (e.g. tif, jpeg) like raw and assigns the raw defaults to them. Is this what's happening? (you can tell by looking at brightness, contrast, sharpness, & color NR. They should all be zero for the jpeg - are they? Ripe for a bug report if so - I'm not sure I ever filed one on this.

              This typically happens when you have a camera default defined. Lightroom should apply completely zeroed settings to reimported tiffs, psds and jpegs, but you can define defaults that change this behavior. This sometimes happens by accident if you happen to alt click the reset button. Another thing to watch out for in your workflow is to make sure to embed the color profile in the saved jpeg. Lightroom assumes sRGB for untagged jpegs.
