Color stripes in dng

[innature]

Hello,

When I convert my raw-files to dng at the import, in some photos it turns up color stripes. They are not present when I have imported the pictures but as soon as the converting starts some pictures are affected. What to do?

This is a hardware malfunction somewhere, causing the files to become corrupted. It could be the card reader or USB cable/USB port, bad camera card, hard disk going bad or computer memory going bad.

The fact that they look okay initially is because you are seeing the JPG preview in the file, which is often not corrupted even though the RAW image is corrupted.

When I studied it a little more I realized that it was when some presets I had automatically on the import was don that the problem occur d, not  when the dng conversion was made. It isn't the cards because it looks the same even with new ones. When I import them once again it usually becomes ok. I will try next time not to have the presets. Seems as that might be the problem.

I'd be shocked if a preset did this change to the images. I can't image how such a preset would be created. But let us know.

It's an ordinary preset with sharpness, contrast, clarity and some other things you usually do to all your pictures.

Ordinary presets don't have the effect that you show in your screen capture.
