DNG Thumbnail Display In Windows

Smoke665 · 09-01-2016, 05:14 AM

Is there a difference in DNG fIles. The thumbnails display on the DNG files from my K30 but not from my K3 II in Windows 10 file Explorer. What am I missing????

Have you downloaded the latest codec?

Technically there isn't much of a difference, but windows probably looks at the camera model.

No I haven't. I can't understand though why the DNG files from the K30 show thumbnails but those from the K3 II don't unless there is a difference in the files. If one works shouldn't the other?????

Maybe the number of megapixels is the cause (pixels height and width).

There is a substantial difference in file size

Sometimes, codecs look at the metadata and look for the camera model. The codec you have might say something about a Pentax K-30 but nothing about a Pentax K-3ii, so it "thinks" it can't support it, even if there is no actual difference.

In reality, I suspect this is an issue more often than people realize. I suspect a lot of issues with camera support happen mostly because of newer camera bodies not being in a table of supported cameras, and support is as simple as the name of the camera. I suspect there are few differences between Pentax DNG files.

However, the K3ii has certain nuances about the DNG file (possibility of an HDR or Pixel-Shifted raw file) that a codec may struggle with.
