I'm using a Scan Dual II to scan slide films and depending on the particular slide I sometimes need to do quite a bit of fiddling with the colours and curves to get the scan's colours to look like those on the original slide (mainly Fuji Sensia II). I'm curious for those of you who use Vuescan with the Scan Dual II to scan slides what you use for scan settings:
eg. Auto colours vs. neutral vs. white balance vs. none (for colour balance)
Auto exposure or manual exposure
Colourspace setting (AdobeRGB, sRGB, ...)
Right now I am using colour balance=NONE, auto exposure, gamma 2.2, image brightness=1, and sRGB mainly because it seems to give me acceptable results most of the time. I am importing them into Photoshop 6 and doing most of my colour correction there. Any advice?
