Why do I have a white band on bottom of images in LR

    Recently I've been seeing a white band at the lower left had edge of some images taken at less than 50mm. See the image I've attached. I'm wondering if it has anything to do with the NEX 6's automatic adjustments or how LR 5 converts the ARW files. Any ideas or suggestions are appreciated.

    Check the jpgs straight from the camera. Could be a shutter problem. Does it happen more so at faster shutter speeds like 1/2000th?

    Sorry I didn't get the image posted on the initial posting.

    The shutter speed of this image was 1/125th (@ f5.0). Lens was SEL 16-70Z. I've seen this white stripe in images taken with my SEL 50 1.8. Thus I don't think its a lens issue.

    Thanks for your input.

    take one portrait style and see if the band moves to portrait or stays landscape.

    post results here, it will help me diagnose the problem :p

    It looks like there has been some rotation or distortion correction done to the image in Lightroom. Are you sure that you don't have some automatic preset enabled that is performing either of those adjustments?

    Woodworks, Yes this image was processed with a lens profile correction preset. However, I have several images that were not imported into LR using that preset that also have the white band. Thanks for your help.

    Mathieu, Yes the white band moves accordingly when shooting portrait. (I'm at work right now so I can't post examples.) Thanks for your help.

    The white band has a very sharp border with the picture so that doesn't look like a shutter issue, in that case I would expect a more gradual transition. Could you put up a raw file for download (at DropBox or so) with this problem?

    I don't think this has anything to do with a lens profile. Given the slanted, hard edge, I suspect some image rotation and cropping is going on here. Did you perhaps sync settings in Lightroom with some other (rotated) image? What happens if you just press the Reset button on that image?

    One more question: have you tried opening the file in anything other than Lightroom?

    WoodWorks, I downloaded Fast Stone Viewer and looked at some of the images right from the SD card. There were no white bands. Then I went back into LR and checked the history on as many of the affected images as I could remember. They were all imported with using a Lens Profile preset. When I went to the Develop Module, Lens Correction section under the Manual tab several of the sliders were moved, including rotate and vertical. For the first image I looked at I moved the rotate slider back (it was at 2.6) which resulted in a straight horizontal white band. By sliding the horizontal slider back to zero, the white band disappeared. So I guess my initial question has been answered. Thanks to all who helped.

    Yeah, that's not shutter bounce, I couldn't see the image before.
