This post may only be relevant to anyone using Nikon's raw conversion software, Capture NX-D.
Background: Over a month ago a NEF file showed up as being corrupted when displayed in Capture NX-D. I thought that perhaps the corruption was due to my using an SD card that was nearly 5 years old. So I switched to a new card and for the past month it seemed as if the issue had been solved. That changed yesterday when the thumbnail of a new NEF file displayed as corrupted.
A screenshot is displayed below. Because I was doing some controlled testing of noise at exposures under different iso settings (and the benefit of Topaz DeNoise AI), the entire series of displayed images appears identical. They are not. The single image in the series that displays as corrupted was at iso 200 (between images at iso 100 and iso 400), In this view, you can see that the corrupted portion of the image is prominently reflected in the histogram to the right. Later below, you will see that this is not actually the case.
However, when I attempted to convert the seemingly corrupted image, the tiff output appeared complete. Therefore, I began to suspect that something might be amiss with the software. So I converted the file with the only other conversion software I had available (Dave Coffin's dcraw). It also converted the seemingly corrupted file without issue and its histogram was normal. In dcraw, there is no thumbnail preview so I never observed the presumed corruption.
Because the version of Capture NX-D I use has not been updated for several years, I uninstalled the program and installed the latest version. Shown below is a screenshot of the same NEF images displayed in the newly installed version of Capture NX-D. Clearly there is no corruption of the file and the histogram of the same image at the right is reflective of a non-corrupted image.
Perhaps this post will help someone else. But perhaps not. I may be the only human to have ever been the victim of software that misbehaves "intermittently".
