NegaFix is the intelligent negative function
with support for more than 120 film types and an 'exposure'
slider. This function allows the user to produce brilliant
quality images from negatives.
The negative-positive conversion of standard-exposed
and developed negatives using SilverFast's NegaFix can be
achieved with a few easy steps.
The NegaFix window offers three pop-up menus and a slider.
The pop-up menus are used for the selection of the appropriate
characteristics of the negative film:
a) Manufacturer, or film brand b) Film type or film name
c) Film speed (sensitivity)
By means of the slider, or the input field, the film exposure of the negative
can be adjusted within plus/minus 3 f-stops.
Image Frame Selection
Ensure the selection marquee is inside the image and does not touch the
perimeter of the film material. The image on the right has been automatically
optimised with the integrated "Standard Profile".
Select Film Manufacturer
Select manufacturer or negative film brand: e.g. Agfa.
Select Film Type
Select the film type: e.g. HDC.
Select Film Speed
With the pop-up menu, select the film speed (ASA/ISO-value) of the actual
film. All chosen settings will be instantly updated in the preview
window.
Correct Film Exposure
Normally, a correction of film exposure is not necessary. In case of the
image appearing too bright or too dark, use the slider to simulate a
film exposure of ± 3 f-stops. You will see the correction in real-time
on the preview.
Apply Auto-Adjust
Now the process of negative-positive conversion is complete. To fully optimise
your image just press the SilverFast auto-adjust from the tool bar as
usual and/or apply other SilverFast tools as desired.
