I intended to read a DNG formatted image with the code rawpy.imread(path), however it returned me with a error message, saying unknown file: data corrupted at xxxxxxx (7-digit number).
Following this error, I found the program is still able to continue to run anyway, and the DNG image is not a flat one, since when visiting its property of raw_image_visible, it returned me with a ndarray of four channels. I have the lastest version of rawpy package (0.16.0) under Windows 10 environment.
I shared the photo via Google Drive. I have no idea how I can address this issue. Any kind of help is appreciated.
