Re: filmscanners: Color Calibration



The reason I say this (as to the 3 cards) is that I have been working on several
interior shoots lately, one is a home with lots of white (how many shades of 
white
paint are there?) walls... I kept getting deeper and deeper into the muck until 
I
figured out that if I used the ultra bright kitchen lights as my white point, 
then
found a suitably deep shadow on a black chair for the black, then guessed at 
what
part of the gray countertop to set the middle and bingo! the thing popped into 
good
color range... I then tried doing the same with my Minolta scanning software, 
even
tho I am setting it to spit out 16 bit linear scans via TWAIN into PShop... that
seems tyo help as well, particularly with the highlight details and not having 
the
colors too far off balance... I really haven't done any detailed comparisons, 
so I
can't say with any scientific certainty if it's all just my impression or if it
really does make a difference.

What I would like to know is your opinion of Vue Scan as the medium for 
controlling
the linear or raw scans into PShop instead of my Minolta software.. I have been 
too
busy to take the time to figure out VS for my purposes...
