Video enhancement filters
There is no such thing as perfection. Although modern digital camcorders use high
dynamic range CCD and CMOS imagers and advanced algorithms for processing
your shots, you still need to adjust a number of settings on your video equipment.
Sometimes, there is no time for that so the footage gets either under- or
overexposed, has bad color representation or both.
Thus, Enhance Lighting and Color Correction tools become valuable
instruments you can use to perform a number of color-related adjustments.
Enhance Lighting Tool
Enhance Lighting is a video filter for exposure control in underexposed or
overexposed footage. There are two controls in the dialog box: Fill Light and
Enhance Shadows.
Fill light adds light to the image's darker areas to improve the lighting on
underexposed images.
Enhance shadow enhances the shadow on the image's highlighted areas to
improve the lighting of overexposed images.
To apply the Enhance Lightning filter:
1. In the Timeline, select a clip on which the filter will be applied.
2. Click Clip: Video Filters.
3. In the Video Filters dialog box, select Enhance Lightning from the
Available filters to the left.
