Ultra Contrast
Tiffen was recognized with a Technical Achievement Award from the Academy
of Motion Picture Arts and Sciences for the Ultra Contrast optical filter which
redistributes ambient light to capture details that would be lost in shadows.
Contrast is lowered evenly throughout the image with no flare or halation.
1 Apply Ultra Contrast from the HFX Diffusion category.
2 Try out some of the presets.
3 If the Parameters window is not showing, click the Parameters tab at the bottom
of the Presets window.
4 Adjust the Shadows > Shadows slider to brighten shadow areas.
5 Adjust the Highlights > Highlights slider to darken highlight areas.
In some of the filters, a selection is generated to create the desired effect--in
this case, lowering contrast.
6 Change your View to Shadows or Highlights to see the selection values.
The areas that are white in the selection are the areas that will be adjusted by
either the Shadows or Highlights sliders. The areas defined as Shadows or
Highlights can be adjusted by modifying the Position and Range parameters.
7 Use the Shadows or Highlights > Position parameters if you want to select
different values to be used for the selection.
8 Increase the Shadows or Highlights > Range controls to add more values to the
selection. Decrease for less values.
9 Change your View to Output to see the image.
10 Click the Done button to apply the filter to your image.
See the Ultra Contrast filter on page 460 for more information.
