Help please, the attached is a jpg taken directly from a NEF. It is one of two from a batch of about fifty taken the same day on the same SanDisk CF card. The two have a brightly coloured horizontal line through them. The example is X200 & cropped in Capture NX2 latest version. The suspect pair were taken within two minutes of each other so are consecutive on the card.
Strangely the line is seen in Capture NX2, viewed in Photo Mechanic and View NX2 the line is definitely not present although it is there if opened in Windows Photo Viewer. The remainder of the batch are perfectly OK.
All are of a similar subject the same day in similar conditions.
I agree with changing out the card. Perhaps. Were the images uploaded straight from the camera, via USB or Wi-Fi, or read by a card reader? If it was uploaded via a card reader perhaps a direct upload test using the USB cable is in order? Perhaps it's the card reader?
This does bring up a general question: are images, written to a card that has been in use for a long time, recorded and uploaded with the same quality as those recorded and uploaded when the card was new? Let's assume the aged card was faithfully re-formatted prior to each use.
Almost new card from a major UK Photographic dealer. Why if its the card does it not show in View NX or Photo Mechanic? Always upload via a card reader and ingest with PM before opening from there into Capture NX2.
