[filmscanners] RE: Bands while using Vuescan
I too was wandering what is this Linear scan is. Its good idea to scan with minolta s/w and process with vuescan. I get the control and also I will get to know whether Vuscan's post-scan processing is causing bands. I will try.

But now I am forced use Minolta s/w, It has options to select Color space, Monitor device RGB, these option are hidden!!!. Another thing is minolta s/w will not embedd the color profile into image. Have you tried doing a 16 bit raw (linear) scan to file from the Minolta software with autoexposure turned off and then processing the file in Vuescan? This isn't much slower (although it is best not to have both open at the same time as this can cause the scanner to hang!) and would give the degree of control you are after. Al Bond (ANOTHER ISSUE) Another problem which I faced few times was, that I used to get full RED images(no other thing except RED). During the scanning process, Vuescan shows Pre-processed image and post-processed image in the s/w. Pre-processed image used to look fine but final file written to harddisk used to be washed with RED. Seems there is some thing wrong in the preprocessing.

I wonder whether we are discussing the same sort of banding in the red channel. I posted a couple of examples, comparing the results with the earlier version of the scanner: http://mysite.freeserve.com/filmscanners/elite_vs_eliteII.jpg (Crop of full frame for reference and full resolution extract from each scanner - 470KB) http://mysite.freeserve.com/filmscanners/elite_vs_eliteII_channels.jpg (Separate channels of full resolution extract from each scanner - 307KB) If this is the sort of banding you are seeing in Vuescan, then I think you may be right that Minolta have partly fixed the problem in the software. What version of the Minolta software are you using?
