Creating a negative profile
NOTE: Before attempting this procedure, be sure that you have tried the standard Negative Pro-
files supplied with ColorQuartet as well as the customizing method described under “Preview-
ing and scanning negatives.” They should give acceptable results for most images.
1 • Using the relevant type of color negative film, take a photo of a reference image.
2 • Mount the negative in the scanner and make a preview scan with ColorQuartet, activating
the Negative check box.
3 • In the Preview window, draw a crop frame that includes both the unexposed film base and
some fully exposed areas, and double-click inside the crop area.
4 • Choose the desired Negative Profile from the menu in the Color Definition section of the
Scan Setup window.
5 • From ColorQuartet’s Calibration menu, choose Edit Negative Profile.
6 • When the desired setting has been achieved, save the new profile by choosing Save from
the Negative Profile menu in the Negative Profile window.
The image must include the full exposure range, from fully exposed to
unexposed values. Alternatively, an existing well-exposed image or
strip of images may be suitable.
IMPORTANT: Make sure the crop area does not contain any clear areas
of the scanner drum or mounting plate, including sprocket holes in the
negative, and that it does not include any obvious dust or dirt.
• To customize an existing profile, choose it.
• To start from scratch, choose Uncalibrated.
• The Negative Profile window will appear and you can use its functions
to
fine-tune the profile.
• Use the feedback window to evaluate the effect of the negative profile. You
will probably base your changes partly on a subjective visual analysis and
partly on the values shown by the on-screen densitometer.
A standard dialogue will appear from which you can assign a name and
location to the profile.The new profile will automatically appear in the
Negative Profile menu in the Scan Setup window.
