The auto white adjustment in print will always set the white level balanced at level 1000 (10 bit). This means it is imperative that you run the auto white calibration on the brightest frame in the clip that you are scanning with that setting.
There has been some suggestion that we should increase the overhead on the calibration to ameliorate this problem but with any reduction in that value of 1000 there will be increased noise in the blacks. Because the scans are in a logarithmic scale a fairly small reduction in this overhead can cause a fairly marked increase in black noise.
If you are seeing whites entering clip during the scan this would suggest that you have calibrated on a frame that was too dark. I can only assume this is what you are seeing when you say the image is too bright. The scan settings should always have whites as high as possible otherwise they will be noisy. You should not be adjusting so the image looks correct at this stage all that should be the case is the whites just out of clip.
There can be a colour cast to some black and white stocks even though the whites are balanced unfortunately which as you say has to be corrected out in resolve by reducing saturation. Ideally we would add an extra film type to the scanner for black and white stocks but this has not yet been done.
Let me know your thoughts, cheers
