I guess you mean the badpixel.bin dummy file from reply #3 ?
So there's going something wrong while creating your own badpixel.bin file - how did you create the file ?
I run <show_bad.exe> in command line interface on my pc.
You should NOT use the dummy badpixel file, otherwise the bad pixels which normally will be removed by the original Canon firmware will be visible as black dots in you DNG images.
I am aware of that...
yet the whole point to shoot RAW for me is to leave the files untoched by the Canon firmware.
thanx anyway for your input.
