Alex,
I did try using the cblack[] values but they also were zero. I did find that the Canon.ChannelBlackLevel[] values were populated. I am going to check all three (imgdata.color.black, imgdata.color.cblack[] and Canon.ChannelBlackLevel[]). The first non-zero value I find will dictate what value I use. Do you agree?
