By the time you get your Tiffs vuescan should have already done what darktable is doing with its basecurve i.e. allow for the characteristics of different films/sensors/cameras. I would have thought the simplest, or at least most obvious, approach is just to open a few of those scans in dt and see if you like the look of them as they are. If you find that they tend on average to benefit from some tone/colour/whatever adjustment why not just save that as a style and apply it in bulk?
This is assuming you have already taken your scans and have the Tiffs and you are not proposing to rescan them with Vuescan producing raw scans and dt handling the tone curves? (which I wouldn't recommend at all as this is Vuescan's home territory on film characteristics and it does it well) Rgds, Rob. -----Original Message----- From: junkyardsparkle [mailto:[email protected]] Sent: 24 October 2013 06:55 To: [email protected] Subject: Re: [Darktable-users] Creating Base Curve to process scanned film In this situation, what you would be developing a base curve for would be the film type (and desired effect), rather than the scanner. In fact, you may even be better off doing this in the scanner software, if you're not saving as high-bit-depth tiff files.
