[filmscanners] Re: Vuescan 7.4 raw scan files not realy raw?

O.K. In the mean time I learned from the readme files that
this is documented and that you can use the
size reduction under the filter tab to reduce noice.
In this case you can use this setting as an image quality enhancement, wich
unfortunately reduces the raw scan file size.
I did this with older Vuescan versions before, but the raw scan file was
saved in full resolution and only the cropped tiff file was reduced in size
(and noice).

When you want to save an unprocessed raw scan file in full resolution AND
you want to save a tiff (crop) file with less noice you can choose size
reduction on the tiff (crop) file setting under the files tab.

The more options in VueScan, the more confusing the settings are...
