Silverfast and HCT

[cowgum]

I have some targets from Hutch Color which I want to use, instead
of the IT8 targets, to generate the scanner profiles. But I want
to know which settings should I put in the Silverfast. I was advised
to disable colour management by the guys at Hutch Color, which I
am able to easily do so in Nikon Scan. However, I am a bit confused
with the settings to use in Silverfast. Bascially, I need to get
RAW data scans of the targets and I would import them into the EyeOne
to generate the profiles. The settings should be the same as to
how I would be subsequently scanning the rest of my photos; I would
be scanning them without any colour management. ie RAW data scans.

Here is what I thought the settings should be, please kindly advise if I had got them correct.

Color Management:
Scanner -> Internal: NONE
Internal -> Monitor: AUTOMATIC
Internal -> Output: RGB

Profiles for ICM:
Scanner(Transparency): NONE
Internal: NONE
Gray: GENERIC GRAY PROFILE
Rendering Intent: PERCEPTUAL

Am I getting all the settings correct, esp for the "Internal" part??
I would want a scan that has absolutely no embedded profiles.

thks!!!

When your settings are:

Color Management:
Scanner -> Internal: NONE
Internal -> Monitor: None
Internal -> Output: RGB

Profiles for ICM:
Scanner(Transparency): NONE
Internal: NONE

the colour management is switched off (you get pure raw data) and no profiles are embedded!

I would add that once you have created the profile in i1 Match you should use it with SilverrFast. You can see the settings in Example 5 at this link:

thanks to both of you for answerig my questions!!

[cowgum]

Err...I have another question to add to this. Is it okay to say, instead of setting the "internal" to "NONE", can I set it to a particular profile, say "AdobeRGB", and leaving all the other settings as it is. Would it be advisable to do that??? Does that mean that then I will be constrain to the characteristics of the profile??

[President_LSI]

Adobe RGB for "Internal"

You can select "Adobe RGB" for internal; that profile might be embedded in the raw data. Your data itself will not be effected!

[cowgum]

I'm sorry I do not really get what you mean by "might be"??? So what will be the difference between setting a color space and none?? Can you kindly explain??

tks!!!

[ilyons]

"might be"???

I think you will find that it "will be".

I had tried what you had described, however, the scan that I have got is really too dark for any good, and especially not for a scanner profile. I understand the RAW scans to be darker than the usual scans, but I am getting them really really dark. 1/4 of the swatches are in black, is that suppose to be that way?? Do you have any other suggestions to get a better scan??

i believe that if you are getting raw data, then no gamma correction has been applied and what you describe is true - the scan looks black. All the data is there, however.

and if that is the case, try setting the Gamma-Gradation value in Options:General, and turning the 'use in HDR' option On so that the RAW data will be gamma corrected.
