Nikon’s ViewNX 2 software has been installed but never used. (The D7100 is the latest in the series, a 24.1 megapixel digital single-lens reflex camera model announced by Nikon in February 2013.) I switched my Nikon D100 for a D7100 a year later in November 2013. We originally purchased Lightroom 4.4 in November 2012. One of my sons has been able to sit down and do some troubleshooting regarding the file corruption issue I’ve been having with NEF/raw photos using my Nikon D7100 imported into Lightroom 4. Original message text from 12/21/14, 9:35 PM: I do think it would be worth the time to install the 30 day trial of Lightroom 5 (use 5.7 which is the latest update), and see how that goes.Īdobe - Lightroom : For Macintosh : Adobe Photoshop Lightroom 5.7 Since you are able to successfully convert those raw photos to DNG, and import those DNG into Lightroom without problem it suggests the image data is fine, and something else is causing Lightroom to choke. In my experience, data corruption is a sign of hardware failing (memory card, USB port, USB cable, hard drive, etc.) and I've never encountered any instance where it was caused by Lightroom. I've never encountered anyone with your exact set of symptoms. We will be troubleshooting using different card readers, USB ports, computers, and conversion software in an attempt to figure out where this problem occurs, but any feedback and suggestions would be much appreciated! After reading the above suggestions, my feeling is the issue is in the hardware chain somewhere.See thread below for a previous troubleshooting attempt with a fellow at Kelby Media Group.After taking the camera back to Nikon for a cleaning, Nikon has strongly encouraged (to put it kindly) the use of its proprietary Capture NX-D software and was not willing to engage us troubleshooting issues with another company's software.The same images went wonky in all attempts, while the others were safe throughout. The top row is the successfully imported images (still trying to figure out how this worked versus the other two attempts), the second the first attempt with DNG Converter 8.7.1 (I think), and the third another attempt after updating to DNG Converter 9.8.0. The following images illustrate the situation. Unlike before, it was only some (roughly half, but not every other) of the 40 that were affected and not every photo in the range. We were happily moving forward using the converted DNGs, until a subset of a batch of 40 DNGs showed the same issue as NEFs the other day. The toggle to embed the original raw file in both Lightroom and the DNG Converter has been tried both on and off with no difference.Up until the other day, it would always be a range of photos, either during generation of the Lightroom histogram or when a Finder preview is generated (Command-I) in Mac OS.Our workaround involved never importing the photos to Lightroom in Nikon's raw format (NEF) and keeping everything in DNG or JPEG format.Photos imported to Lightroom as NEFs without being converted would import fine, then show a rainbow-like skewing of the colour channels when the histogram was generated and displayed in the top-right corner of the Library module.JPEGs have never caused any issue, and neither have NEFs converted to DNGs via Lightroom.Photos are typically imported using a USB card reader using Lightroom's import feature and the copy/copy as DNG options.The Adobe DNG (Digital Negative) Converter has been updated to the latest version (9.8.0.692).A trial version of Lightroom 5 did not solve the problem, so an updated Camera Raw version does not seem to be the solution.
