Is yours RawShooter essentials 2006 change/edited?
Of course, no. After editing rawshooter.exe CHDK DNG looks as black.
So, I change in DNG file header BitsPerSample parameter from 10 bit to 16 bit (using hex editor
). After this RAW shooter can show thumbnail and even main image (of course, main image is corrupted because data is 10 bit in reality).
Hence RawShooter essentials 2006 can not open DNG with 10-bit image. If you want to use it, you must convert images to 16 bit using Adobe DNG converted or something like this.
