Adjusting Tonal Range; Using The Levels Feature; To Apply A Live Filter To An Area Defined By A Bitmap Selection Marquee - MACROMEDIA FIREWORKS 8-USING FIREWORKS Use Manual

If you apply a filter to a selected vector object using the Filters menu, Fireworks converts the
selection to a bitmap.

To apply a Live Filter to an area defined by a bitmap selection marquee:

1.
Select a bitmap selection tool and draw a selection marquee.
2.
Select Edit > Cut.
3. Select Edit > Paste.
Fireworks pastes the selection exactly where the pixels were originally located, but the
selection is now a separate bitmap object.
4. Click the thumbnail of the new bitmap object in the Layers panel to select the bitmap
object.
5. Apply a Live Filter from the Property inspector.
Fireworks applies the Live Filter only to the new bitmap object, simulating the application
of a filter to a pixel selection.
Although Live Filters are more flexible, large numbers of Live Filters in a document
can slow down Fireworks performance. For more information, see

Adjusting tonal range

You can use the Levels and Curves features to adjust a bitmap's tonal range. With Levels, you
can correct bitmaps that contain a high concentration of pixels in the highlights, midtones, or
shadows. Or you can use Auto Levels and let Fireworks adjust the tonal range for you. If you
want more precise control over a bitmap's tonal range, you can use the Curves feature, which
lets you adjust any color along the tonal range without affecting other colors.

Using the Levels feature

A bitmap with a full tonal range should have an even number of pixels in all areas. The
Levels feature corrects bitmaps with a high concentration of pixels in the highlights,
midtones, or shadows.
Highlights
corrects an excess of light pixels, which makes the image look washed out.
Midtones
corrects an excess of pixels in the midtones, which makes the image bland.
Shadows
corrects an excess of dark pixels, which hides much of the detail.
