Filter's interface

Correct illumination

Filter's interface - illumination enhancement
Filter's interface - illumination enhancement
  1. Source image has very bright and very dark region - Processing image has HDR frames. Control using makes contrast low.
  2. Brighten dark region - Allows to illuminate dark frame regions. Dark regions won't be processed if control value is equal to zero.
  3. Reduce bright region - Allows to restore light-struck frame regions. Light regions won't be processed if control value is equal to zero.

Correct colors

Filter's interface - color enhancement
Filter's interface - color enhancement
  1. Correct colors - Saturation setting control. If value is set in zero saturation won't be changed. Note: recommended in use with Auto Levels.
  2. Auto levels - Automatic levels correction. One reflects source frame illumination to all allowed illumination range.

Let's consider job of the filter on a test rollers.
