Re: Canoscan FS4000US green and grainy

I use this scanner with Vuescan, and can give you settings for a number
of films that should be quite neutral if you use the same films and
would like to see if you get better results. I'm using 8.3.55 which
works fine.

I have saved ini files for Reala, 160C, 160S, NPZ, 400UC, and 100UC
that use the advanced workflow. Email me at the address I use with
this group if you want any of them.

Best,
Roger

Film was not blocking the slit but that was a good suggestion. The
best suggestion was trying the Canon software. It proved that my
problem was not with my scanner!

I had originally tried reinstalling VueScan 8.3.38 but the results
were the same as with the new 8.3.57. So it wasn't a glitch in the
upgrade. I just didn't recall having this much of a problem earlier
but I haven't scanned film in quite a while.

In any event I previewed a known dense daylight neg and made my
adjustments in VueScan to get a reasonable scan. It's not spot on but
at least I'm in the ballpark.

For anyone who wants the readings, this is for Kodak Portra 400NC with
a Canoscan FS4000 and is only a seat-of-the-pants setup:
Color Balance: Manual
Neutral Red: .79
Neutral Green: 1
Neutral Blue: .91
Black Point: 0
White Point: 1
Curve Low: .251
Curve High: 75
Brightness: 1
Brightness Red: .76
Brightness Green: .565
Brightness Blue: .76

I'm using these settings now to scan some thin negatives (I believe my
developer screwed up and didn't tell me because I did a lot of
bracketing but you wouldn't know it) and the results are good so far.
Of course there is always the possibility that something happened to
my flash since I used it quite a while ago. The variables will kill
you!

Now, if anyone tries these settings and comes to the conclusion that I
must be crazy, please let me know. I also found that some old
Ektachrome 160 is scanning green using the VueScan settings but I
haven't tackled that yet.

Thank you all,
Brian Wickham
