How did you pick what the right black areas are? |
I used dcraw to get a pgm file. Then I loaded the pgm file into GIMP and brightened the image. This is from the top left corner Horizontal...perhaps I did wrong there. What is your opinion? I moved 12 px down and used 0 height. The top area is 100% black and grey and I don't want rawspeed to use that area at all. |
Changed from Vertical x=0 to Vertical x=5 when the first 4 columns are not black.

Also fine tuned black level reading for Canon EOS D30 by adding horisontal black level. This part is not as important as the one for Canon EOS D60. Free raw sample https://discuss.pixls.us/t/measure-black-and-white-levels/32082/4?u=peter
