Thank you for your responses!
@Brian, lossless compressed NEF
@Nikonian, I actually pulled that card from my d7100 at the end of my shoot, did not reformat (leaving 100 d7100 images on that card), shot 40 more photos (only 3 of which were affected).
Just tested opening the NEF in camera raw and still see the horizontal lines.
Thanks for noting the slowness of the Ultra's, agreed! and usually i do shoot on an Extreme Pro or Extreme card, just was the tail end of the shoot and grabbed the old card from the old camera. I am now retiring that card but still want to know if it was the culprit.
Attaching the actual photo & a screen capture of the Camera Raw screen... It's hard to see the lines in the thumbnail that is posted, so i'm attaching a zoomed in screen capture. . . the lines fun the full length of the image.
Thanks again, this is so helpful
Thanks Ron, the card is reformatted so image is gone . . . but there is no big loss as the photo affected is not a master, nor a critical image. I'm going to retire the card. And I'm going to start coping to hard drive before importing to LR. I used to do that, great idea!
