    I was briefly reviewing some sunset images that I shot the other night before culling and importing them into Lightroom. In the middle of the review, I noticed that several of the images were partially posterized in the shadows. Granted, I am viewing the embedded jpeg image in the raw files when I use FastStone Image Viewer for reviewing, but similar sunset shots from earlier in the week did not exhibit this problem. I will need to import the raw files and view them in the develop module of Lightroom for a closer examination, but as this is the first time that I have seen this problem, I was wondering if anybody else has had a similar experience. I'll try to post some sample images for comment when I get a chance.

    Thanks,

    Until I am able to actually analyze the raw file, I have clipped a 100% sample of the embedded jpeg for you to see.

    It needs to be flipped 90 degrees, but this part of the image was the water reflection near the horizon line.

    Good news. I quickly created a test catalog in Lightroom and imported the image. The raw file, and the preview created in LR look fine. I am not sure why the embedded jpeg posterized, but the ORF file seemed good. I hope to import the entire shoot this weekend, and will report back if there are any problems.

    maybe the embedded jpg was just a low quality preview purpose highly compressed image

    It's possible, but I never noticed it when quickly previewing images outside of Lightroom before. When time permits, I'll see if I can review some older files.

    It could also be a dynamic range issue with so many bright and dark areas.

    +1. That would be my guess.

    I am not near my camera now, but I believe there is an option for highlight and shadow adjustment in JPEG that compresses highlight/shadow detail. Is this enabled? Perhaps someone else can chime in with details.

    Gears/color WB/Shading Compensation.

    Try turning that off.

    I checked the setting, and it was already off. But, it was a good suggestion, and a control setting that I was not aware of.

    Thanks,
