Nikon 5000 camera. I am converting nefs to dng. I am new to this whole area. I am trying to figure out why previews ina given software (IDImager) look different for the dng vs the nef. As an aside I am looking at eh exif data. For the nef the data are:
Image Length: 120
For the DNG
Image Width: 256
Image Length: 170
Why are they different? And does it matter since as I understand this only for how the RAW data are viewed in any preview and have no effect on the actual "raw" data.
If you're talking about the JPEG preview image contained within the files, I think the DNG converter is simply creating a little bit larger preview image. This does not have any impact on the raw data.
